[U-Boot-Users] New NAND subsystem and JFFS2 images

[U-Boot-Users] New NAND subsystem and JFFS2 images

[Guido Classen]

Hello list,

I am trying to test the new NAND code on our board. It was upgraded to a
128MiB NAND chip with 2k page size. The chip is detected correctly and the
usual NAND commands seems to work.

But I can't successfully write a JFFS2 image to the NAND for later usage as
Linux root filesystem. The JFFS2 related commands "nand erase clean", "nand
read.jffs2" and "nand write.jffs2" seems to be not implemented in the master
and the testing-NAND trees and neither I have found a patch fixing this on the
list.

Is there an other way to achieve the same effect? Or is there somewhere an
existing patch, I haven't found yet?

Best regards

  Guido

Dear Guido,

as far as I know, such patch doesn't exist yet. I have few other patches
pending and to be honest my motivation is very low now, given that:
1) Noone commented them so far.
2) Even people who complained in past that something doesn't work remain
   silent when there is a need for testers.
3) I do not need this functionality (however this will change in few weeks)
4) I'd have to learn maintaining incremental patch series ;-)

As always, either implement it yourself or wait for someone else to do
it.

Best regards,
