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'.

Uboot> erase all

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
