Can anyone help me? I'd like to partition my SD card in order to have an ext2 part for software installation and a fat one for data exchanging

Sure.

I'm assuming you're using RC5 btw. The locations are a bit different in 1.0.5

in a console do...

umount /mnt/card
fdisk /dev/mmcd/disc0/disc
p (see what partitions you have)
d (delete em)
n (new partition)
p (primary)
1 (when asked for the endpoint use the +50M option/ substitute 50 for how ever big you want it)
w (writes to disk)
mkfs.ext2 /dev/mmcd/disc0/part1 (formats it)

then pull the sucker out and sick it in your windows box and use the disk manager to add a fat partition after your linux one. formating fat32 works fine for me fyi.

You can also create both partiton on the z, just be sure to change one of them to the Fat in fdisk. "t" command in fdisk.. doing it in windows is prolly the easiest way tho

hope that helps

going to try.

Thank you for the tip

I used fdisk to create a 256MB ext2 partition, then used the Disk Management tool of WinXp to create the fat32 partition in the remaining space.
Everything seems to run fine

thank you

I had to do the whole job with fdisk... windows has problems if the fat partition isn't the first of the device.

Does anyone know where can I find automount settings? they are not in fstab, actually

I partitioned my 512MB SD with a 135 MB FAT partition 1 (for flashing and NAND backups) and an ext3 partition 2. I had to edit /etc/sdcontrol to change the "DEVICE" (line 11) to part2. I also had to edit /etc/fstab to give me a mount point for partition 1 (I used /mnt/fat).

that's what I needed

I'm going to modify the /etc/sdcontrol so that both partition will be mounted on inserting, and storage functions will act on the fat one.
Suggestions?

Good idea, I will be very keen to get a copy of this when you're done!

I suggest you modify it to use fstab for the list of SD partitions to mount. So just do something like this:

Code: [Select]

for i in $(grep /dev/mmcd/disc0 /etc/fstab | grep -v -e noauto -e swap | awk '{ print($2) }'); do
    mount $i
done

That way people can choose which partitions get mounted, where they are mounted to, the filesystem type and any mount options.

You should also check for swap partitions on the SD card and use swapon to activate them.

Hi. I am trying to do a similar thing. Would it be possible for someone to post the modified /etc/sdcontrol (and any other files) please?

Thanks
Simon

EDIT: just realised that this is the pdaxrom forum- I am running OpenZaurus with Opie- will there be much difference?

rgrep · « **Reply #11 on:** November 11, 2004, 01:27:01 pm »

I'm working on the replacement script now so I'll post it when I've finished. There shouldn't be much difference but if you post your copy of /etc/sdcontrol then I can compare the differences and release a version that will work on OZ.

systemparadox · « **Reply #12 on:** November 11, 2004, 03:06:42 pm »

Attached is my /etc/sdcontrol. I changed the device from mmcda1 to mmcda2.
Can I have both versions of the script when you are done please?

Thanks a lot!
Simon

Has anyone finished the modified version of this script?

I don't know if the the scripts are the same between the ROM's, but I modified the sdcontrol on a 5600 under OZ. Check out the thread [a href=\"https://www.oesf.org/forums/index.php?showtopic=9945&hl=]here[/url]. HTH
