Other Parts Discussed in Thread: OMAPL138

Hello,

  I want to run the ARM_LED Blinking program in LCDK. Firstly, i converted the "OMAPL138 ARM-LED.out" file into ais.bin file using AISgen. Then, I flashed that file into SD card by using the command " sudo dd if=ais_file.bin of=/dev/sdx ", then i want to boot the LCDK in SDMMC0 boot mode, for that i made the bootswitch 4(SW1-no.4) as ON. Then i what i have todo to blink the LED, whether ther is any initial steps i want to do in LCDK board?...


Thanks,

Ilayaraja

    Can you get it to work in the debugger?  

    One problem I saw was that the LCDK LEDs are GPIO, but some examples are written for the EVM board which uses I2C.

    I have an LCDK and I was able to get one program running on the DSP and one on the ARM both blinking different LEDs.  For the ARM, I modified the starterware ethernet echo example and modified the starterware bootloader.  For the DSP I started with a blink LED example but made many changes  I had to make sure to enable PSC for GPIO and set the pinmux registers for the LEDs (I did that in the StarterWare bootloader in bl_platform.c).   I burned all the code to NAND to test it but I haven't tried an SD.

    Hai,

     I got the "Linux host shell" (Serial Terminal Window) to enter the commands started with "host $" , but where i can found the "U-Boot Shell" and "LCDK- Linux Shell" to enter commands starting with "EVM #" and "target $" respectively ?

    Thanks and Regards,
