JFFS2 and compact flash

a couple weeks ago, I sent mail to this list about using JFFS2 on a compact flash card, but haven't received any answer...

can anyone answer me, or point me to a document describing the procedure it it is at all doable ?

Probably because compact flash isn't really flash. See the bottom of linux-mtd.infradead.org

It's probably doable, but only via the blkmtd driver. There have been some recent discussions on this. Take a look at the archives from last week.

Hi,

I guess it depends on how the compact flash is presented. If it appears to the system via a hard drive interface (?) then the answer would be yes.

I'm running JFFS2 on USB Flash keys (which appear as SCSI devices via /dev/sd??) via the MTD block device emulator .. the default read speed is poor and the write speed is non-existent .. however if you grab my patch for blkmtd.c posted earlier, I'm pretty much getting raw read/write speeds from the key.
