All,

Trying to boot up / debug my board with a Rev 1.2 MPC8360E.

After the kernel launches from U-boot I receive no serial debug, and the system hangs.

I am running U-boot 1.1.6. Dirty <which does contains support for the 8360>,

I have walked through the DTS/blob file, after U-boot modifies it, <I turned on all the debug info>, and can clearly see that the /chosen node, etc.. is getting entered. My original DTS file already has all of the clock speeds entered <modeled after the MPC8360xx.dts file that was already in the DENX-2.6.19.2 kernel release>.

I have limited debug ability via some GPIO leds on our board, I can see that the kernel starts to run and at least gets to the point where it clears all the BATs <powerpc/boot/head_32.S and setup_32.c>, at which point I lose access to the IO space and can no longer write out to the debug lights. Unfortunately I do not have access to a COP debugger at this point. It doesn’t seem to get to the platform files, or at least I can get the GPIO access inside the IMMR space to work correctly.

Does anyone have any suggestion per software only debug method that might be enabled? Or a way to temporarily hack the early serial output so I can see what is going on?
