I am a newbie to Embedded linux and I am unable to get SCC4 working as my
console device for my custom board. I am using Linux 2.4.24 from ELDK 3.0.
U-boot works greats with SCC4 defined as my console device. I must use SCC4
as my console device because my board has no more pins left that I can use.
In addition, I can not use the hardware handshaking pins as well. I only
have the 2 wires - Rx and Tx available. I am using all 3 FCCs and using an
SMC as a serial port is not an option due to its intensive FSM and drag on
the CP.
I attemptted to boot linux but it traps at console_printk. After the trap,
the SCC4 Registers look good to me so I guess the port has been initialized:
GSMR_L4 00028034 Tx and Rx enabled
GSMR_H4 00000020
PSMR4 B000
TODR4 8000
DSR4 7E7E
SCCE4 0107
SCCM4 0000
SCCS4 03
The log_buf contains the following:

A few seconds later the console terminal spews pages and pages of the

I'm using the uRamdisk (SELF) image found in ELDK 3.0 as my ram disk. My
boot session and config files are attached
Any suggestions on how I should preceed?
Thanks in advance!
