Hi, I use the mtdoops get:
mtdoops:Cannot write from panic without panic_write.
What the mtd partition filesystem shoud be?
I try a jsff2 system, so get the warning like above.

Can it be that your MTD driver does not support the panic_write interface?

Em, as the message said, I think MTD driver does not support the
panic_write interface.
1.Is a writable filesytem enough for mtdoops like jsff2?
2.Is the panic_write interface highly related to the flash device(I use
the winbond 32M)? Or is it a common layer interface of mtd.
