olimex ? 2012 olinuxino user's manual chapter 2: setting up the o l inuxino board 2. introduction to the chapter this section helps you set up the olinuxino development board for the first time. please consider first the electrostatic warning to avoid damaging the board, then discover the hardware and software required to operate the board. the procedure to power up the board is given, and a description of the default board behavior is detailed. 2.1 electrostatic warning olinuxino is shipped in a protective anti-static package. the board must not be exposed to high electrostatic potentials. a grounding strap or similar protective device should be worn when handling the board. avoid touching the component pins or any other metallic element. 2.3 requirements in order to set up the olinuxino optimally , the following items are required: - 6v to 16v source of power with 1a maximum amperage. - sjtag interface programmer - usb keyboard - monitor with composite interface or personal computer + usb-serial-cable - sd card with linux image note that the board arrives without sd card or linux image. you can purchase a card with linux separately. it is recommended that the user has basic linux experience. some of the suggested items can be purchased by olimex, for instance: imx233-olinuxino-sd - sd card with the linux image usb-serial-cable -f - usb serial console cable female (check 6.1.1 uart debug for info how to connect it to the board) sy0612e - power supply adapter 12v/0.5a for imx233-OLINUXINO-MAXI page 8 of 50
olimex ? 2012 olinuxino user's manual 2.4 powering the board the board is powered either via the pwr jack or via a battery. it should be supplied from a 6v to 16v source with maximum current of 1a from the power jack. all measures below are taken at 10v. if measuring the current consumption it should be around 0.06a before initializing all the peripherals. the consumption raises to 0.12a without lan and usb hosts initialized and linux running. the consumption goes up 0.15a with the linux running when lan and both usb hosts initialized. if you have a standard usb flash drive attached to a usb host, linux and lan running the typical consumption is around 0.20a. when powered by the typical 3.7v battery the lan and usb-hosts will be powered-off if you use the external 3.3v dc-dc (they will stil work if using the internal in the processor dc-dc). the consumption from the battery when linux is running is around 0.75a. important! we discovered a situation which might leave some of the sd cards (imx233- olinuxino-sd) in unrecoverable state when powering olinuxino-micro. the problem might occur if two specific conditions are met simultaneously: 1)plugged imx233-olinuxino-sd micro sd card with holographic sticker on its back side (some of the cards we have distributed are from a brand that places holographic sticker on their backs, the other half lack such a sticker) 2)plugged usb-serial-cable-f at the moment when powering the board if you happen to have received sd card with holographic sticker on its back side and you use it with olinuxino-micro and you plug usb-serial-cable and then you power the board there is a chance of malfunction of the sd card. there are two possible workarounds to protect the sd card. the first one is simpler and the second one requires some soldering experience. workaround 1: first insert the imx233-olinuxino-sd card and then power the board (and if powering the board from a battery also press the pwr button). wait 4-5 seconds and then connect the usb-serial-cable-f. after the initial power-up it is safe to use the reset button. workaround 2: you will need a shottky diode. the shottky should be soldered on the usb- page 9 of 50
olimex ? 2012 olinuxino user's manual serial-cable-f tx line/wire (red cable) with anode towards the board. when you power the board by battery you have to press the pwr_but to start the board. if you start linux and it is already running no matter which powering method you use (pwr_jack or bat) pressing the pwr_but will put the linux in power-save mode. when you power the board by battery you have to press the pwr_but to start the board. if you start linux and it is already running no matter which powering method you use (pwr_jack or bat) pressing the pwr_but will put the linux in power-save mode. for the european customers we sell a power supply adapter 12v/0.5a - sy0612e. 2.5 prebuilt software note that the boards arrive without linux or sd card . the linux image can be purchased separately on a sd card or you can built and adjust it yourself. when we program the boards we change the default position of the following hw_ocotp_rom0 fuses of the processor: sd_mbr_boot(3) - blown sd_power_gate_gpio(21:20) C 10-pwm3 for burning the fuse position we use the bitburner software. this operation is discussed in details before. proceed with great caution when burning fuses since it is irreversible operation. 2.6 using bitburner important! modifying the fuses is irreversible process! burning the wrong fuses might damage olinuxino irreversibly! burning wrong fuses might cause boot problems! burn fuses at own risk! the bit burning is done via the usb of the computer connected to the olinuxino board and the bitburner software. to be able to burn the fuses you will need to make a custom cable that connects a usb with the 3 pin holes found at the bottom of the board named gnd, dp, dm (check the picture below for a better view how the three wires must be connected. page 10 of 50
olimex ? 2012 olinuxino user's manual after soldering the three wires you can place a marker on each of them or use colored wires to be able to distinguish them. you can also use some gel to keep them tight on the usb connector. on the opposite side of the cables you might place 50mil (1.27mm) male connector following the order of the signals. please also restrain from using wires longer than 20 cm since that might make the connection unreliable. download bitburner from https://www.olimex.com/dev/olinuxino/imx233- olinuxino/bitburner.v1.0.4.6.zip . extract it and start the .exe. if you connect everything you should see and choose hid-compilant device from the select device drop-down menu. page 11 of 50
olimex ? 2012 olinuxino user's manual 2. 7 building the linux image note that building the linux image from scratch is a time-consuming task. even with powerful machine and fast internet connection it might take few hours compiling. some linux distributions might lack the tools required to compile/build/execute scripts/download from repository C how to get those is not discussed below. the linux image is created and downloaded from https://github.com/freescale/fsl-community-bsp- platform . for the test here we used debian 6.0 with gnome visual libraries. the steps we did: 1) from the terminal created folder bin in home folder: user@dist$: mkdir bin user@dist$: cd bin add bin directory to path in order to do the next steps easier. else navigate to the right folders. 2) installed `repo` utility needed for the bitbake file fetching from the repository: user@dist $: curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo user@dist $: chmod a+x ~/bin/repo 3) created directory for the project and d ownload the bsp source from the git repository : user@dist $: mkdir fsl-community-bsp user@dist $: cd fsl-community-bsp ~/fsl-community-bsp $: repo init -u https://github.com/freescale/fsl -community-bsp-platform -b denzil ~/fsl-community-bsp $: repo sync 4) you can change the settings for the build if you want at fsl-community-bsp/build/conf/local.conf. i changed the machine name to imx233-OLINUXINO-MAXI. for linux kernel configurations and settings you can do (of course you can use also the default settings): ~/fsl-community-bsp$: . ./setup-environment build ~/fsl-community-bsp/build$: bitbake linux-imx -c menuconfig check the image below: page 12 of 50
olimex ? 2012 olinuxino user's manual 5) now to start build ing the image : ~ fsl-community-bsp$: . ./setup-environment build ~ fsl-community-bsp/ build $: bitbake core-image-minimal note: on different linux distributions you might have different tools installed and you will probably need to install dependencies needed for the compile/build scripts. here are some (but not all) of the mandatory ones: g++; diffstat; texi2html; chrpath; gawk; texinfo; some git client. to ensure you have the latest version supported with all the updates visit https://github.com/olimex/olinuxino and https://github.com/freescale/fsl-community-bsp- platform . 2.8 how to blink the led in this sub-chapter you will find a way to achieve the most basic task in electronics C the hello world of electronics - blinking the led. first we set the pin responsible for the led as an output and we can set its value manually to high or low position C make it blink manually. the led mounted on the board uses gpio65. you can use external diode instead of the one mounted - you have to look at the table the linux implementation of pins in the hardware section to get the correct linux name for the gpio pin. page 13 of 50
olimex ? 2012 olinuxino user's manual echo out > /sys/class/gpio/gpio65/direction echo 1 > /sys/class/gpio/gpio65/value if you want to set the blink off you should change the value on the second line to: echo 0 > /sys/class/gpio/gpio65/value to show the info for all gpios: ls /sys/class/gpio to make it turn on C turn off automatically (e.g. blink) we use the text redactor vi to write the linux script: echo out > /sys/class/gpio/gpio65/direction while true do echo 1 > /sys/class/gpio/gpio65/value sleep 1 echo 0 > /sys/class/gpio/gpio65/value sleep 1 done we save it as as gpio and we make it executable with chmod +x gpio then we execut the script with: ./gpio t he led should start blinking with 0.5 hz. 2.8 how setup the i2c, spi, uart good place to check if you are trying to configure the i2c, spi, uart etc via linux is http://www.inf.furb.br/~maw/asm51/telit_ge863-pro3_linux_sw_userguide_r5.pdf . telit have explained how to do it with their board but it follows the same pattern for olinuxino. another way to test i2c is using the i2c-tools utility (), which is available in openembedded. for spi you can use spidev tool: page 14 of 50

olimex ? 2012 olinuxino user's manual chapter 5: control circuity 5. introduction to the chapter here you can find information about reset circuit and quartz crystals locations, the power supply circuit is discussed. 5. 1 reset olinuxino's reset circuit includes r 9 ( 47k ), r10 (47 ), t1, t2, q1 and a reset button. the reset is specific for the fact that it is accomplished when the quartz is disconnected using 3.3v and the transistors t1 and t2. 5. 2 clock s 24 mhz q uartz crystal q1 is connected to pins 121 and 122 of the imx233 processor. 25 mhz q uartz crystal q2 is found at pins 60 and 61 of the ethernet controller C lan9512-jzx. 5.3 power supply circuit the power supply circuit of OLINUXINO-MAXI allows flexible input supply from 6v to 16v direct current. this means a wide range of power supplies, adapters, converters are applicable. the maximum amperage recommended is 1a by default (0.250ma if 3.3vio_e is closed C read below). all measures below are taken at 10v external supply. page 21 of 50
olimex ? 2012 olinuxino user's manual if measuring the current consumption it should be around 0.06a before initializing all the peripherals. the consumption raises to 0.12a without lan and usb hosts initialized and linux running. the consumption goes up 0.15a with the linux running when lan and both usb hosts initialized. if you have a standard usb flash drive attached to a usb host, linux and lan running the typical consumption is around 0.20a. when powered by the typical 3.7v battery the lan and usb-hosts are disabled. the consumption when linux is running is around 0.75a. the board can be powered either from the power jack or from the lipo_bat connector. note that since standard batteries can't provide the voltage needed for the board it is advisable to use the power from the power jack. when you use the lipo_bat connector and a battery the chip handling the ethernet and the usb hosts is disabled. also the power button has alternative function when the board is powered by a battery C check 6.13. if you have successfully powered the board the red pwr led will turn on. note that it is possible to have the pwr led on even if there isn't enough power for proper operation of the board and all the peripherals currently connected. page 22 of 50
olimex ? 2012 olinuxino user's manual the jumper 5v_e (5v enable) which is closed by default enables powering the board via the power supply circuit. the 3.3v_e (3.3v enable) jumper when closed enables the 3.3v power line. note the 3.3vio_e jumper which by default is closed C if you open it (cut it) - it disables the u6 dc-dc converter and enables a built-in the imx233 dc-dc. the problem is that the built-in dc- dc has a limit of 250ma of amperage the chip heats a bit so we decided to put external dc-dc for better stability. when working with 3.3vio_e closed pay attention to the amperage used. if 3.3vio_e is closed(soldered) C it enables the additional dc-dc which is the better solution if powering the board from external supply. however, if 3.3vio_e is closed and you power the board from a battery the lan and the usb-hosts will not receive enough power and will be disabled. page 23 of 50
olimex ? 2012 olinuxino user's manual chapter 6: connectors and pinout 6. introduction to the chapter in this chapter are presented the connectors that can be found on the board all together with their pinout and notes about them. jumpers functions are described. notes and info on specific peripherals are presented. notes regarding the interfaces are given. 6.1 debugging interfaces if you don't have a separate monitor or display around, and you don't wish to swap cables constantly with your personal computer using the debug interfaces provide better option for you olinuxino experience. there are three debugging options available on the olinuxino. it is preferable to use one of the first two - uart or sjtag but in case you want to use the classic 6-wire parallel jtag there is an option explained below. page 24 of 50
olimex ? 2012 olinuxino user's manual 6.1.1 uart debug the first one is a debug uart interface C u_debug. you can use our usb-serial-cable for debugging via the uart. in order to avoid sd card malfunction, when using the usb-serial-cable-f with OLINUXINO-MAXI it is advisable to first insert the imx233-olinuxino-sd card and then power the board (if using battery also press the pwr button). wait 4-5 seconds and then connect the usb-serial-cable-f. please also check 2.4 powering the board for detailed info. note on how to use the u_debug with usb-serial-cable-f which has red green blue wires gnd=blue, rx(input)=green, tx(output)=red. y ou have to connect to OLINUXINO-MAXI u_debug connector in this sequence: blue wire to pin.3 (gnd) green wire to pin.2 (tx) red wire to pin.1 (rx) u_debug pin # signal name processor pin # 1 pwm0/duart_rxd 125 2 pwm1/duart_txd 126 3 gnd 30, 35, 98, 105, 112, 118 4 debug 84 you can also check the pin names at the bottom of the board under the u_debug header. 6.1.2 sjtag debug the second interface is the serial jtag (sjtag) one-wire interface. it works with various external jtag debugger dongles through a freescale-defined fpga/cpld. sjtag supports the green hills slingshot and etm probe debugger dongles, as well as those made by arm, abatron, and lauterbach. page 25 of 50
olimex ? 2012 olinuxino user's manual note that the sjtag interface comes without plastic header mounted. the hw_digctl_ctrl_use_serial_jtag bit in the digital control block selects whether the one-wire serial jtag interface or the alternative six-wire parallel jtag interface is used. there are other options in the digital control block which might interest you and our advice is to check the imx233's datasheet released by freescale. sjtag pin # signal name processor pin # 1 3.3vreg - 2 gnd 30, 35, 98, 105, 112, 118 3 sjtag_psw 119 4 debug 84 the pin names are also written at the bottom of the board for your convenience. 6.1.3 c lassic jtag debug the third option is to use the classic 6-pin parallel jtag (not including gnd and vcc). there are pads left for this option at the bottom of the board under the sd card holder. they are named individually and framed near a jtag name. the important thing is that these pins are multiplexed with the sd card signals. in order to use the 6-pin jtag you will have to stop using the sd card. note also that the classic jtag interface comes without plastic header mounted so in order to use it you will need to use wires for connection. consider the the software settings required to switch from sjtag to 6-pin jtag and vice verse referring to the imx233 manual. for instance: the hw_digctl_ctrl_use_serial_jtag bit in the digital control block selects whether the serial jtag interface or the alternative six-wire parallel jtag interface is used. hw_digctl_ctrl_use_serial_jtag - 0x0 - selects whether the one-wire serial jtag interface or the alternative six-wire parallel jtag interface is used. 0 = parallel six-wire jtag is page 26 of 50
