Hi Mark,

I've just updated from v2008.10 to v2009.01 on my AVR32 board (MIMC200).
JFFS2 no longer works (it hangs at "Scanning JFFS2 FS:", so I've done a git bisect, and here's the result:-

Is this a known problem ?
No, I've never heard of it. Could you please be more specific? What type of flash do you using? What is the size of your JFFS2 partition? How did you create your filesystem?
The JFFS image was made using Buildroot, and I think it's just over 5MBytes (size = 0x4d0000 bytes).
The image itself is fine, since if I install v2008.10, the target boots (into Linux) as expected.
The flash is an 8MByte device (Spansion P/N S29GL064N90TFI04).
I have taken an existing, working board, and simply installed v2009.01 (rather than v2008.10). The target boots into U-Boot fine, and I can read / write the env variables, and, obviously, I'm able to write U-Boot itself !!

Under v2008.10, when I do an 'ls', the line "Scanning JFFS2 FS:" is shown, along with a spinning - \ | / - character sequence.
Under v2009.01, the "Scanning JFFS2 FS:" text is shown and the target appears to hang (i.e. no spinning cursor, just a solid cursor).
I have also tried a new board (with blanked flash). Under v2008.10 'ls' comes up with a "filesystem not found" type of error. Under v2009.01, again the target just appears to hang.
I guessed that no-one else has this problem (since the bad commit was back in November), but it's definitely broken for me !!
I'm happy to help diagnose / fault find.
Regards Mark
