= How to boot your IGEPv2 board<br> = First of all, you may want to boot your board. IGEP0020 can boot from the next devices (listed by priority)#REDIRECT: *from a MMC/microSD card ([[How to boot from MicroSD Card|here]] is a complete tutorial about how to set it up)<br> *from OneNAND memory. <br> The IGEPv2 board boot process is divided in '''3 booting phases''':<br> #[[The bootloader X-loader|xloader]] boot process (It's not possible to interact with the board). #[[The bootloader U-Boot|uboot boot]] process (It's possible to interact with the board using the console). #[[The Linux kernel|Linux Kernel]] starting process (It's possible to interact with the board using the console when the kernel has already started).<br> = How to set up and log in<br> = IGEPv2 board uses the serial debug for output all debug information and the users What can interact I do with the board.

Now you are ready to login. You can do it via: *'''Serial Console''': [[Using serial debug port to communicate|here]] is a short explanation about how to correctly configure your Serial Console<br> *'''SSH''' The default login user is: '''root''' There is '''no password''' for this user. == Using the board LED's<br> == This is probably the most simple feature in the board, but sometimes LED's may be the only way of checking the status of some of your applications.<br> === Turning LED's On/OFF<br> === IGEP0020 has 4 LED's which you can control, for example, using 'echo': <pre>echo 1 > /sys/devices/platform/leds-gpio/leds/d240\:green/brightness echo 1 > /sys/devices/platform/leds-gpio/leds/d240\:red/brightness echo 1 > /sys/devices/platform/leds-gpio/leds/d440\:green/brightness echo 1 > /sys/devices/platform/leds-gpio/leds/d440\:red/brightness</pre> You can turn them down using the same command and write '0' instead of '1'. === LED's triggering<br> === You can change the trigger of the leds (none by default) to different modes: mmc0, mmc1, timer, heartbeat and default-on.<br> To enable this modes you just have to change a parameter in the directory of the led you want to control. You can see all the possibilities using 'cat':<br> <pre>$ cat /sys/devices/platform/leds-gpio/leds/d240\:green/trigger [none] mmc0 mmc1 timer heartbeat default-on</pre> In the example above, we have checked the status of the trigger in led D240:green. None is selected. To change it, for example, to the trigger mode you can use 'echo':<br> <pre>echo timer > /sys/devices/platform/leds-gpio/leds/d240\:green/trigger</pre> In this case, we have set the trigger to the 'timer' mode. In this mode you can set the time for what the led is ON and the time it is OFF using:<br> <pre>echo 250 > /sys/devices/platform/leds-gpio/leds/d240\:green/delay_onecho 750 > /sys/devices/platform/leds-gpio/leds/d240\:green/delay_off</pre> Now the selected led is configured with a timer consisting of 250 miliseconds ON and 750 miliseconds OFF.<br> <br> <br>
