You can find the word G4, MPX, and 60x in gtreg.h.

Ok.

I printed those three registers during gt attachment and enabled DEBUG. Hope
this helps:

Your and my difference is CPU_Mode, CPU_Master_Ctl, and DRAM slots.
However, there is perhaps no problem.

  CPU_Mode=00000050 CPU_Master_Ctl=00003b00

  gt0:      scs[0]=         0-   0xfffff
  gt0:      scs[1]=         0-   0xfffff
  gt0:      scs[2]=         0-0xffffffff
  gt0:      scs[3]=         0-0xffffffff

If you believe me, you can boot by my kernels.

What do you think is wrong with it?

This one panics before interrupts are enabled, while attaching the keyboard
(which was not physically present, because I was booting with a serial
console):

Sorry,  I mistook.  And this debug-log is ugly...

gdbserver for powerpc

Hi,

I have added the support for netbsd on powerpc to gdbserver.

You can find the patches in NetBSD problem report bin/43332.
When you follow the instructions in the sections How-To-Repeat and Fix,
you get a working gdbserver for netbsd on powerpc.

After applying the patches in PR port-powerpc/43196
and PR toolchain/43219 too,
you should be able to start the gdbserver on a powerpc board
running netbsd and debug remotely from a linux host.

I have done more changes to netbsd, because I am using a board with
MPC5200B CPU.

Best regards

Jan
