hi !

I would like to format my 256Mo CF card to ext2 in order to stock progs on it. I try to follow those instructions from pdaxrom homepage

Code: [Select]

When i'm installing programs(IPKs) to SD or CF card it fails? 

A:
You must format the SD/CF card to ext2: 
Format CF: 
umount /dev/hda1 
mkfs.ext2 /dev/hda1 
mount /dev/hda1 /mnt/cf 
Format SD: 
umount /dev/mmcda1 
mkfs.ext2 /dev/mmcda1 
mount /dev/mmcda1 /mnt/card

but it does'nt work...

Code: [Select]

# umount /dev/hda1
umount: /dev/hda1 not mounted
# mkfs.ext2 /dev/hda1
mke2fs 1.34 (25_Jul_2003)
/dev/hda1 is mounted; will not make a filesystem here!

Any idea ?

check you're not in /mnt/cf whiletrying these ... you could also try umount /mnt/card instead of /mnt/hda1 ... in last resort you can edit your /etc/fstab, comment the line which is mounting /dev/hda1 and reboot your Z (without the card) then re-insert it, format and then uncomment the line ... btw you shouldn't have to come to that

tried with umount /mnt/card but then mkfs gives me the same while i am in the / directory...

I dont know if its the same setup as with SDs, but when you format a SD its
/dev/mmcd/disc0/part1 rather than /dev/mmcda1

the cf might be similar to that, something like
/dev/hda/part1, /dev/hd/disc0/part1 or some such thing

just a stab in the dark tho

Murple, took me a while to see what I was doing wrong with pdaXrom and the SD card. OpenZaurus was just /dev/mmcda.

Anyway, I sacrificed a CF card to test, and it works fine for me. RC5/C860

Maybe you should try it without X. Also, might as well do

Code: [Select]

cardctl status 0 and make sure its not some big problem.

Stab in the dark indeed No, it's /dev/hda1. Check the output of 'mount' with no arguments, it shouldn't show the cf card as mounted.

EDIT :

Man ! progs on the CF card are sooooooooo slow.... Plus everything doesn't work properly out of the box... Not so sure anymore it was a good idea...

oki, it was definitly a bad idea... my cf card is much to slow...

now, how do i revert back ? mkfs.msdos ? mkfs.vfat ?

Why don't you try before asking? mkfs.vfat
