Angstrom & OpenZaurus / How To "mount" Cards As Usb Mass-storage With Oz

« on: April 29, 2006, 08:38:53 am »

I finally got it working with my microdrive.

The new kernel 2.6.16 in oz-3.5.4.1-rc1 did the trick. I takes some time until windows recognizes the drive, but some seconds ago i finished a download to the drive, and no errors whatsorever.

The microdrive is partitioned as usual. One partition, with one logical drive in it, formatted with fat32.

The modprobe command is the usual one

Code: [Select]

modprobe g_file_storage file=/dev/hda
Thanks for providing an OZ with this new kernel.

No partition?

Yes, no partition. All i wanted was a logical drive where i can create the file i would be using as a backup for g_file_storage on. So i decided to create a superfloppy. Win probably does not like it, but oz did not have a problem mounting it.

to look up arg names for modules modinfo <module name> can come in handy

Thanks, i wasn't aware of that. All i did was looking into the source code file on my gentoo box, where i did find some of the parameters one can give to g_file_storage gadget.

BTW, I use a C860, which has 2 bad eraseblocks, if that matters.

I also have some problems with g_file_storage.

I use the command

Code: [Select]

modprobe g_file_storage file=/dev/hda
for both my 256 MB compact flash card and my IBM 340 MB microdrive, which both have a fat partition.

I tried 3.5.4 and 3.5.4.1.

I tried to mount them under Linux (2.6.16-ck1) and under win2k.

The compact flash card works, after some time (about 1 minute). The card is recognized as Linux File Storage, the fat formatted drive is recognizd and usable under win2k just like a normal usb stick.

The microdrive does not work like the flash drive. Neither Linux, nor win2k detect the partition, only the drive is recognized, either als Linux File Storage or as sdb. So with g_file_storage the microdrive is not usable. Of course it can be mounted under OZ 3.5.4 and 3.5.4.1, and i can install ipkgs from it.

I even tried to make a ext2 partition on the microdrive, then make a file on that partition, and make a partition inside that file, formatted it and then used this file as the parameter for g_file_storage. It also did not work.

The listing for the latter:

Code: [Select]

mkfs.ext2 -m 0 /dev/hda
mount /dev/hda /mnt
dd if=/dev/zero of=/mnt/store bs=1M count=340
fdisk /mnt/store
modprobe g_file_storage file=/mnt/store
Maybe some devs may take a look at it. Probably a newer kernel (2.6.16) is a solution for problems like these. I have read somewhere (lkml or so), that in 2.6.16-mm1 there are some bugfixes for the gadget devices. Unfortunately there is not much information on this topic out there, the file storage gadget howto is a good source of information, but there are no solutions for problems like these.
