Hi Prafulla/Albert,
Thanks alot for your help. Finally using kwbimage.cfg solved the problem and my openRD_client came up :)
Now, I want to boot Uimage and Filesystem from an MMC card. But the MMC support was not enabled, I added the configurations for MMC support to openrd_cleint.h. --------------------------------- /* MMC support flags */ #define CONFIG_CMD_EXT2 1 #define CONFIG_CMD_FAT 1 #define CONFIG_MMC 1 #define CONFIG_GENERIC_MMC 1 #define CONFIG_CMD_MMC 1 -----------------------------------------------
But the U-boot doesn't detect the card. From the startup messages, I observed that the driver for Kirkwood openrd_client is not found from u-boot. Is there any patch or work around available to enable the boot from MMC ?

Then I tried using USB. But when I use the commands to load uImage into RAM, some messages are shown and it never stops. I had to power cycle to go u-boot prompt again. So loading any file/image into the RAM is not working :( can you please help me on this ??
Please find the logs:

you should use u-boot.bin to load in RAM @ 0x600000 (TEXT_BASE)
That's what I do, either through JTAG or by tftp/go in resident u-boot.
for boot from RAM, you must need at least SDRAM configured, so JTAG is the
way
JTAG does work indeed. Howvever, when:
- I power up the board;
- ROM boot loads u-boot from NAND and starts it;
- I stop u-boot and get to the prompt;
- I 'tftp' an u-boot.bin image into RAM at 1000000;
- I 'go' to 1000000
... the tftp'ed image fails to boot although SDRAM is obviously already configured.
OTOH, openOCD boots the RAM image fine, so I guess OpenOCD does some inits that the boot rom plus resident u-boot don't.
Amicalement,
Albert.
