UART Problems booting linux on est8260

[Latsky Sterren-LTSS001]

Hi.

I'm trying to boot linux-2.4.22 on the est8260 board using U-boot-1.1.1, but the serial interface corrupts after this line comes up:

=> bootm
## Booting image at 00400000 ...
   Image Name:   Linux 2.4.22
   Created:      2004-08-10  15:55:04 UTC
   Image Type:   PowerPC Linux Kernel Image (gzip compressed)
   Data Size:    523580 Bytes = 511.3 kB
   Load Address: 00000000
   Entry Point:  00000000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... OK
Memory BAT mapping: BAT2=16Mb, BAT3=0Mb, residual: 0Mb
Linux version 2.4.22 (ltss001@linux) (gcc version 2.95.3 20010315 (release)) #3
..
Kernel command line: root=/dev/nfs rw nfsroot=192.168.0.1:/tftpboot/192.168.0.2
ip=192.168.0.2:192.168.0.1::255.255.255.0::off panic=1
...
CPM UART driver version 0.01

I have looked around and found that the next line should say something like

ttyS00 at 0x8000 is a SCC

But all I get is garbage like musical notes and square root signs streaming onto the terminal. I have tried changing the baud rate when this comes up to all the other options but I still don't read anything coherent.

When configuring the kernel I tried just loading the est8260_config, then building without editing the menuconfig, when that didn't work I went to menuconfig > Character devices and fiddled around with various options in there but nothing seems to work.

Any help would be greatly appreciated. Thanks,
Sterren Latsky

Some "mouloud ameni" asked the very same question on the etux mailing
list one hour before you. I replied to his question.

Please coordinate internally who is posting to which list instead  of
wasting our time and bandwidth.
