Dear linuxbios.
Hello.
I've worked for development of Embedded linux project in my
corp.
Following is decription of my projcet.
CPU : VIA C3 800Mhz (EBGA)
Reference Board : VT6015
Northbridge : VT8606 (include S3 twister video
core)
Southbridge : VT8231 (include VIA rhine II LAN
core)
Bootbios : Linuxbios
OS : linux 2.4.19 ( ramdisk include
glibc 2.3.1, busybox 0.60.5 and tinylogin 1.2 )
Now, It works well except hard disk.
I try to boot the kernel in two way.
First, it loads compressed kernel and ramdisk image via
network using tftp protocol.
Second, it loads elfImage, generated by 'mkelfImage' via
network.
All of them work great. (It means that I can see the prompt '\
'.)
But, when I try to make a file system the
harddisk, 'segmentation fault' occurs.
mke2fs and mkreiserfs have same problem.
For find out the cause, I try to make a file system in
various method.
1. Buildin Bios + Redhat 8.0 installed harddisk + test
harddisk
2. Linuxbios + Redhat 8.0 installed harddisk + test
harddisk
3. Linuxbios + Kernel(newly compiled), own ramdisk + test
harddisk
After boot, I try to make a file system on test
harddisk.
In case 1, It works well. Of course, it must
be.
In case 2 and 3, I meet the segmentation fault.
So, I think that this problem caused in
Linuxbios.
Maybe, this problem caused by harddisk initialization in
linuxbios.
But, there are no harddisk initialization code in
linuxbios.
Cound you help me?
Thanks for reading.
Regards,
malas
PS. In addition, memtest86 v3.0 works well without
error.
Follwing is boot messages.
