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
Please press Edit - Preferences - Remote Connections, select your debug probe in the list, click "Change", new window with debug probe settings will appear, in this window please enable "Use JTAG Configuration File" checkbox and "Choose" button below. Here please select and pick one of MPC8308* files from the following folder:
[your CodeWarrior path]\PowerPC_EABI_Support\Initialization_Files\jtag_chains\
Have a great day,
Alexander

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
