Hi,
I've been working for 2 days non-stop trying to boot linux from SD0 on a custom OMAP-L138 board.. I've recompiled u-boot to match my settings but nothing seems to be working.
I would really appreciate some pointers... I followed the instructions on this wiki page as far as I could:
http://processors.wiki.ti.com/index.php/OMAP-L138_Preparing_SD_Card_for_Boot
I don't know what I'm doing wrong.. I've also tried loading u-boot through UART boot-mode, the processor seemed to be working to some degree (pulling more amps) but still, no terminal. What is the easiest way to get something up and running from SD0? (also, what would be the easiest way to format the SD card for test purposes only)
My settings are:
- UART0 for communication with PC
- No spi/flash/nor/nand chip..
- 1.3v @456 MHz
- 256 MB DDR2
All help would be appreciated! Maybe I'm not editing the u-boot files correctly?.. Still, the processor was pulling more power (100mA) when I loaded through UART, as opposed to 70~90mA trying to load from SD0.. Is there a way to debug the SD interface as well?
Thanks in advance!!
