Thanks Frank
You're right. It works fine with
    make walnut_config
    make menconfig
    make dep
    make zImage
and the ibm openbios
but i want to use my BDi 2000  Abatron debugger to debug the kernel.
So, i select the following options :
         select CONFIG_BDI_SWITCH
         select CONFIG_MORE_COMPILE_OPTIONS
I download the kernel with the debugger(latest 1.07 firmware). It works
fine (i can put for
example a breakpoint in start_kernel or in do_init_bootmem, it stops at
the right address)
If i continue, nothing happened, the 405GP seems locked in the __udelay
routines.
Is it a debugger config file pb ?
Any idea ? Thanks
