Dear Huang Shijie, How come hector was then able to write his JFFS2 partition ?
If he uses the gpmi, he should not write the JFFS2, since the gpmi does not support the jffs2. He will get the failure in the end.
Hector, can you comment on this?
So the jffs2 support is compatiable all the time.
Is the old Freescale 2.6.35 GPMI NAND format compatible with the one after applying this patchset?
Not compatible.
This patch set is still underreview.
So this patch breaks compatiblity with FSL kernel release? This needs fixing, otherwise it's impossible to do a drop-in replacement for the ancient FSL kernel.
that I could mount with Linux 3.7 and earlier?
I think the mount can be succeeded.
Ok, does that mean that we need this patchset in U-Boot in order to properly write JFFS2 onto GPMI NAND there? Is that the message you wanted to relay to us?
Besides this patchset, the u-boot needs more patches to sync with the kernel mtd code. Such as the full-id features.
Can you elaborate on this more? This is very vague, I would like to know what exactly is missing.
Best regards, Marek Vasut
