[U-Boot-Users] Using SMC1 UART on MPC852T ( AdderII board )

Hi All, 

I am trying to port u-boot on AdderII card(
analogue-micro ) hosting MPC852T. 

Is this already done this before ??

I am trying to configure SMC1 port as a console to get
boot up messages. I have defined 

#define CONFIG_8xx_CONS_SMC1    1

I have a assembly listing, I am using BDI to single
step. It complets "serial_init" function and calls
"display_options" func. This in turn calls ..

printf() -> puts() -> serial_putc().

In the serial_putc func, it goes into an endless loop,

       while (tbdf->cbd_sc & BD_SC_READY) {
                WATCHDOG_RESET ();

The assembly listing is as,

fe0145b8:       7c 00 06 ac     eieio
fe0145bc:       a0 0a 00 00     lhz     r0,0(r10)
fe0145c0:       70 09 80 00     andi.   r9,r0,32768
fe0145c4:       40 82 ff f4     bne+    fe0145b8

Any clues please ??

Warm Regards
