I cannot get the serial console to work on my PPC 8xx (specifically, It is a MPC 866). I have set the console for SMC1:

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

I can see that the SMCMR1 register is set correctly: 0b0100_1000_0010_0011 (CLEN=9 for 8-N-1, 1 stop bit, SM=Uart Mode, TEN & REN = RX and TX enabled) and BRGC1 register is set corectly: 0x0001_069A (enabled, CD=421, div by 1)

What settings should I check and/or where specifically should I debug for the likely error?

Thanks, JM
