[U-Boot-Users] Uboot port issue
Dear all,
I am trying to port uboot onto Rattler board. This board is a MPC8280 based board. It looks like that the processor gets a machine check exception when it executes cpu_init_f()(further traced to m8260_cpm_reset()) function. Please excuse me for providing only with this input (I am trying to gather more information on the problem). If anyone has faced this kind of problem while porting uboot onto powerpc processor can provide me with some pointers to the problem, it would be a great help.
With Thanks and Best Regards, C.R.Srivatsan

Check (and re-check) your memory map. IMMR mapping for example.

The memory map was verified. It seems Ok.
Meanwhile I got the line in which the exception occurs:
In m8260_cpm_reset, gd->dp_alloc_base = CPM_DATAONLY_BASE. Here, the system gets a Reset exception. If I run continuously, I get a machine check exception. This is what I am seeing from the debugger. Why is that I am getting a system reset exception at the initialization of DPRAM base.
