(1) I looked back at my errors and I've begun to realise that an Error: a is the correct answer whenever you issue a 'go' to the kernel address as r0/r1 have no chance of being setup correctly i.e. I'm using 'go' as my bootloader.So with that in mind the bootm is the correct approach.

I tried the suggestion from Gerrit and it didn't work fully. However, I don't get the register dump anymore so the load and entry addresses of 0x00000000 certainly has an effect on something. But in the end it just resets to U-boot. See below:

SMDK2410 # tftpboot 30008000 myUbootzimage_comp15.img TFTP from server 192.xxx.xx.xx; our IP address is 192.xxx.xx.xx Filename 'myUbootzimage_comp15.img'.

(2) Gerrit....Are you also using the S3C2410?

(3) So why isn't it booting. Or more correctly why is it resetting after it issues the 'Starting kernel ...' message!! Am I missing some bootarguments?

(4) I've looked at the VIVI bootloader (from SAMSUNG) and I can see a 'mach-type' parameter which can be edited from the monitor interface. I forced it to 100 (from 193) to get MIZI to fail in the same way with an 'Error :a'. Does U-Boot have a similar parameter ?

Thanks again, Dave
