8308 hwconfig word

[hyoungkikim]

hello experts

my board use a flash  for hw reset configration word  ( CFG_RESET_SORUCE is  NOR FLASH)

i changed hw reset configration word to change core clock

but after re-program a flash   a  board won't boot

and hard reset  signal from 8308  is asserted   ( never de-asserted)   so i can't use codewarriror usb tap to re-program a flash

i checked CS0 and address line  singals  and they are  working  ( i think  mpc8308 tries to get valid hw reset configration word)

if hw reset configration is wrong     can mpc8308   assert hard reset signal ?

than  how can i re-program a flash ?

thanks you

Hi Hyoung

Most JTAG debuggers would provide a mechanism

to override RCW. I am not sure about CodeWarriror

you are using but I have a BDI3000 (from Abatron)

and with it, it would possible to define a new RCW in

the config file to override the one from flash and boot

the board properly.

Hope this helps
