I am having the same problem, but on a MPC866. I set the console on SMC1

#define CONFIG_8xx_CONS_SMC1 1 #undef CONFIG_8xx_CONS_SMC2 #undef CONFIG_8xx_CONS_NONE #define CONFIG_BAUDRATE 9600

And can verify that the SMCMR1 register and BRC1 registers are set correctly by u-boot at boot. However I can get nothing out of the console serial port.

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 running :-/.

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 to IMMR_BAR).

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.
