I'm porting U-boot to a mpc 8347 board, based on the mpc8349sys board.
Up until now, I haven't managed to get the serial communication up and
As with the 8349EMDS board, we've kept IMMR_BAR to 0xe0000000.
WM32 0xff400000 0xe0000000 ;MBAR to 0xe0000000
From the tests we've made, the BDI config seems to be fine (after some
tweaking of the RCW and timings for Spansion GL128N flash).
RCW 0x24600000 0x08230000
Since both the serial is not working; and neither is the networking for
the time being; I assume I'm missing something obvious (both are offsets
The board seems to get pretty far in the bootloader (main_loop); but
without serial, querying the values is difficult since
ppc_82xx-gdb/bdi/config does not show the correct values
(display/print) though stepping through the code seems correct.
If anyone has pointers what to look for, config registers, I'd appreciate
them... I guess I must be looking over the problem.
Listen to this. Double the Crichton and you double the waste of time.
