Re: Problem debugging ppc kernel with DDD/GDB/BDI2000 on a custom MPC8260 board

Dear Joao,

in message [ref] you wrote:

on u-boot IMMR was set to 0x04700000, which is acceptable as far as
u-boot is concerned, but not allowed once the kernel is initialised.

The other issue was that the Chip Select was not configured properly on
u-boot (2MB instead of 32MB), which was not noticed in u-boot since the
u-boot never tried to access memory above that region, but caused the
kernel to reset the target.

...

I am using the denx distribution linuxppc_2_4_devel, and I am
configuring it using the TQM8260 default configuration, customising some
CPM settings for UART and FEC.

I would like to point out that you certainly did NOT pick up  such  a
bogus memory map from the TQM8260 default configuration, nor from any
other board maintened by DENX.

Best regards,

Wolfgang Denk
