Hi,
Kindly help me with the following problem:
I tried upgrading my uboot and ended up with nothing on my console..pls help
I'm having a custom board which is almost a clone of the AT91RM9200DK. Only difference is that I'm having only 2MB of dataflash...rest is the same
DataFlash:AT45DB161 Nb pages: 4096 Page Size: 528 .......................... ........................... Bank # 1: Atmel: AT49BV1614 (16Mbit) Size: 2 MB in 40 Sectors Sector Start Addresses: 10000000 10002000 10004000 10006000 10008000 ........................................... .........................................
Initally i had old version (1.2.x ) of uboot running on it tat came from the Atmel site for AT91RM9200DK...
I was trying to update my uboot to the latest version and to start with I did the following
make clean make at91rm9200dk_config Configuring for at91rm9200dk board... make all
And then on the console:
Uboot> tftp 20000000 u-boot.bin TFTP from server 192.168.0.123; our IP address is 192.168.0.38 Filename 'u-boot.bin'. Load address: 0x20000000 Loading: ####################### done Bytes transferred = 117188 (1c9c4 hex)
Uboot> protect off all Un-Protect Flash Bank # 1
Uboot> erase all Erase Flash Bank # 1 Erasing sector 0 ... ok. Erasing sector 1 ... ok. Erasing sector 2 ... ok. ........................ ........................ Erasing sector 39 ... ok.
Uboot> cp.b 20000000 10000000 1c9c4 Copy to Flash... done
Uboot> protect on all Protect Flash Bank # 1
but I ended up with nothing on the screen when I restarted my board. I also tried to change the
#define CONFIG_SYS_MAX_DATAFLASH_PAGES 4096
but didn't succeed...
Can anyone tell me how to get started? (I have my old uboot files saved and know to get back my oldversion of uboot to try the upgrade with proper steps..)
Thank you for your support
Best Regards,
Benny K J
