Sd Support!

[ZDevil]

Now i am trying to reformat the 4GB SD into ext2 and mount it under obsd.
Following Andy's suggestion,
first i used disklabel -E sd0
then choose "a" to add a device
after offset and size,
I am asked to assign an FS type.
The default is "4.2BSD".
I try "Ext2", "ext2", "Linux", but i am told that it is "Unrecognized filesystem type..., treating as 'unknown'"
Then I try "MSDOS", which is supported,
but when i try to save, i got this:

Code: [Select]

Write new label: [y]
disklabel: ioctl DIOCWDINFO: Input/output error
disklabel: unable to write label

Code: [Select]

Write new label: [y]
disklabel: ioctl DIOCWDINFO: Input/output error
disklabel: unable to write label

Read your last post and you'll see why this is occuring.    Here's the quote:

there is no SD write support so installing things to SD is not feasible.

hence, changing the disklabel via the onboard SD slot is unsupported at the moment , Use a supported external SD reader/writer to change the disklabel. However, writing to the SD card will result in the same input/output error no matter what filesystem it has been formatted with.

If you aren't too fussed about what is on the drive I would suggest that you run..

disklabel -E sd0

Then add a partition, possibly a, and set it up in the disklabel then make your ffs or ext2 filesystem from OpenBSD.

@Andy:
How to make ext2 using disklabel? I've tried ext2, Ext2, EXT2, Linux, LINUX, all these are invalid. The man page of disklabel doesn't mention ext2 at all.
Searching "ext2" in the Man page search and i only got fsck_ext2fs ( and mount_ext2fs (.
Any hint? Thanks!

I have fdisked the 4gb SD under the dualboot Cacko. Tried both FAT and Ext2 but the card fails to be recognized under obsd.

disklabel sd0 says:  /dev/rsd0c: Device not configured

fdisk sd0 says: sd0: Device not configured

So I turned to my Mac...
Just found e2fsprogs and installed it in my OBSD setup on Macbook@Parallels.
First I used disklabel -E sd0 to add a partition [a], then choose the BSD4.2 as FS type.
After that I used mke2fs to create an ext2 filesystem on this SD.
This SD can be detected and mounted in OBSD on my Mac.
disklabel sd0 shows two partitions, [c] and [a] (the newly created one).
The card can be detected and mounted in Cacko on my 3200.

But ...

The 4.1 official release doesn't seem to have SD support at all.
So I install the latest kernel (dated 8 May).
Reboot and now the SD is detected.

But ...

on my 3200, disklabel sd0 shows only [c], and no [a].

So, now the card can be read by Mac@OBSD, 3200@Cacko, but not 3200@OBSD!
What do i do?
Did I go wrong in the attempt?
Thanks!

It seems that the current SD support is rather picky. My 1gb FAT16 SD can be detected and mounted, but my 4gb FAT32/Ext2/Ext3 SD simply fails. Hope this will fixed soon.

Thanks, Andy!

i've just tried my 4gb Transcend sdcard under latest openbsd GENERIC#113 and i have the same problem with the same disklabel output... however mine is fat formatted... no hope to mount it ?

Not sure if it is relevant. For cards bigger than 2gb it has to be FAT32. And for now OBSD's SD driver doesn't seem to like FAT32 at all.
