IDE driver problem

IDE driver problem

[Liu Hongming (Alan)]

[-- Attachment #1: Type: text/plain, Size: 3265 bytes --]

Hi All,

I am porting IDE drivers(Since my hardware has endian issue),
and now it could work,however it has some abnormal problems:

I could 'fdisk'  /dev/hda,and partition it into several partitions.
After this,I reboot my board and see all the partitions is there.
Then I 'mke2fs' on /dev/hda1,after this, when using 'fdisk' again,
I found all partitions gone! At this time,I could not access /dev/hda1
any more.However, I could 'mount /dev/hda /opt', it really worked,and
I could create/read/write/erase files in it.

I dumped the first sector of Hard disk and found that it has been
zeroed.Now I dont know what the problem is,since I am not familiar 
with fs parts of linux kernel,and I dont know what 'mke2fs' has done.

Any advice?

Alan

Kaffe's makefiles won't pick up on configuration changes, so any time
you re-configure for a different engine or debug level, you need to do
a make clean.  At least, that's the way it was the last time I worked on it.
If you had a partial build with JIT, then changed to intrp, then you could
get all kinds of strange behavior.  The address range of your error us a
dead giveaway.  It's too high to be the kaffe code segment, but too low
to be a shared library.  It's where I'd expect the heap to be, and where
I remember the JIT buffers being allocated when I was trying to debug
that stuff.

The partition table is written to the first partition
on the device, in your example hda1.
Use mke2fs on hda2 and I am sure it work just great.

Cheers,

Hmm, maybe I should have waited for my first cup of coffee
before replying ;-)
I work with Compact Flash in IDE mode every day where we
use Mac (Apple) partitioning.
My statement is true for that case ( see attach ).

Sounds like your partition data reading is wrong. Print out the
partition table bases and see if they are all zero
