console startup

I have a PPC 8241 board and Montavista's latest 2.6 embedded kernel. It is for an 9272 board so the .config *almost* makes sense. I am having trouble getting the console up on the serial port and am searching for a few ideas.

There is a "progress" routine in gen550_dgb.c that does display some modest serial strings and it works. I can see after the kernel starts these few progress messages but none of the normal printk stuff beginning with the following from the 2.4 Montavista kernel.

Linux version 2.4.17-d30 (buildmgr@swmpu) (gcc version 2.95.3 20010315 (release/MontaVista)) #30 Thu Aug 10 19:07:44 PDT 2006 On node 0 totalpages: 16128 zone(0): 16128 pages. zone(1): 0 pages. zone(2): 0 pages. Kernel command line: root=/dev/mtdblock0 ip=192.168.56.190:192.168.56.44:192.168.50.2:255.255.255.0:hn0000000053300063:eth0:off OpenPIC Version 1.2 (1 CPUs and 138 IRQ sources) at fc040000 time_init: decrementer frequency = 25.000000 MHz Calibrating delay loop... 133.12 BogoMIPS Memory: 61608k available (1288k kernel code, 468k data, 72k init, 0k highmem) Dentry-cache hash table entries: 8192 (order: 4, 65536 bytes)

I have traced with an ICE through console_init in start_kernel and it looks reasonable, but yet the console never starts. And of course, being a new kernel, I need to see those messages to get things setup correctly.

Any suggestions would be greatly appreciated.

Can you print the bootenv settings you have, is there a "quiet" settings enabled. If there, remove that.... I am also a bit inquisitive if the serial driver really working....although u r getting some of messages work...anyways, let me know if it works...

Once I completed Montavista's incomplete serial driver, the serial port starts up and "debug" on the command line works fine. It amazes me that they ship their product incomplete, but even more amazing is the fact that my new company actually paid for it without demanding they demonstrate it works.

Anyway, thanks for the advice Sudip, it has a terminal now & I can NFS mount the root file system and move forward.
