So I took a chance and bought a 4 gig SD card
I thought it wasn't working...
Dec 6 17:11:10 localhost kernel: mmcblk0: mmc0:b368 SDC 4020224KiB
Dec 6 17:11:10 localhost kernel: mmcblk0:<3>mmcblk0: error 1 transferring data
Dec 6 17:11:10 localhost kernel: end_request: I/O error, dev mmcblk0, sector 0
Dec 6 17:11:10 localhost kernel: Buffer I/O error on device mmcblk0, logical block 0
Dec 6 17:11:10 localhost kernel: unable to read partition table
but then I ejected and reinserted and noticed /dev/mmcblk0
and /dev/mmcblk0p1. I mounted, and there it was:
/dev/mmcblk0p1 3.8G 7.7M 3.6G 1% /media/4GSD
Right now it's an ext2 drive, but I'd like to make it jffs2 instead.
How do I create a jffs2 filesystem? the documentation is really
confusing and the mkfs.jffs2 wants to make a tree from existing files.
