2008-02-27 09:21:50     fail to upgrade from 1.1.3 to 1.1.6

Jian Ju (HONG KONG)

Message: 51738    toolchain: 08r1-8

u-boot: 07r1/08r1 (both were tried)

hardware: BF533 stamp board

 

The board had already flashed u-boot 1.1.3 and I wish to upgrade it to 1.1.6. u-boot was compiled without errors and here is the kermit output:

 

stamp>tftp 0x1000000 u-boot.bin

Using MAC Address 00:E0:22:FE:06:AD

TFTP from server 158.132.179.178; our IP address is 158.132.179.45

Filename 'u-boot.bin'.

Load address: 0x1000000

Loading: ############################

done

Bytes transferred = 138884 (21e84 hex)

stamp>go 0x1000000

## Starting application at 0x01000000 ...

(It stops here without any information printed out)

 

I turn on the 'DEBUG' feature of u-boot in cpu/bf533/cpu.c in hope I can find where the problem is, but no further output was printed, either. Can anybody help?

 

Thank you,

JJ

Message: 51744    In older versions of U-boot (1.1.3) you should make sure that cache is turned off (icache off, dcache off), before doing the "go 0x1000000"

Message: 53742    Hi , I try to disable both caches but it doesn't help. I'm using BF-537 STAMP and 208R1 uC. When run go 0x1000000 then I got strange characters. Then is necessary to reboot. I don't want to burn it to FLASH. Anyone can help?

the older versions of U-Boot do not support "go" to a new version of U-Boot.

 

Burn it to flash, and you should be OK. If you still don't want to do that - load it over the UART.
