Hi Peter, The code worked fine. I used the 'u-boot-594-nand.bin'. But when it comes to RBoot-> prompt, it stalls for a while and again starts the BOOTME sequence. This is the log:
U:\davinci\UART>Uart-U.exe rboot.bin 2 CreateFile for \\.\COM2 failed 5 failed to open com2 U:\davinci\UART>Uart-U.exe rboot.bin 2 read 3000 bytes from rboot.bin Waiting for boot message from Davinci . BOOTME sending ACK Waiting for begin message from Davinci BEGINsending empty CRC table Waiting for done message from Davinci DONESending data Waiting for done message from Davinci DONEWaiting for UBL message from Davinci ee Rboot->uboot size is 107932 bytes ******************************************************************************** ************************** lDone. # Rboot->g BOOTME What should I do next? I also tried with 'u-boot_nor.bin'. But got the same result. Please let me know more. Thank you. Uday. On 12/21/06, Peter Wippich <[EMAIL PROTECTED]> wrote:
Hi Uday, from the second log you send me (with Rudy's UBL) it looks like everything is fine except that the (hardwired) third level Boot Loader (U-boot) is not found. As I sayed before my program is only an (internal) test tool and far away from a real program. Check the source for filenames / pathes used.
