[Ppcboot-users] need help on 8xxrom

[Raphael B. <rap...@so...>]

hi Salih,

to get involved in the 8xxROM now PPCBOOT development, please join the
PPCBOOT Project Mailing-List at http://ppcboot.sourceforge.net/.

> I am currently trying to move an application from a commercial RTOS 
> to Linux for a Motorola ADS board with an 860 processor. I had asked you

> kernel src and have compiled the 8xxrom successfully. However, when I 
> load the 8xxrom.s19 to the flash and try to run it from there, the 
> thing crashes. Actually looking at 0x2800000, I see that there is no 
> code to run there but the string "8xxROM 0.3.0". I am not very familiar 
> with PPC assembly, but upon examining the code, I discovered that 
> there was an another code(?) section (this is my guess btw) starting at

> 0x2800100: addi r10, r9, 0x1002
>            mtmsr r10
>            mtspr SRR1, r10
>            addis r1, r0, 0xff00
>            mtspr IMMR, r1
