Yes, that's very recent actually and we were testing internally just before releasing it. The reason is also that we didn't have a NAND flash on our reference platform which is the SAMA5D2 Xplained. So we had to wait for a new hardware from our colleagues of the HW team and bring it up before working on this NAND flash support (24 bits ECC and sama5d2 new modifications in fact). >> Developments in progress are listed in the Linux4SAM page: >> http://www.at91.com/linux4sam/bin/view/Linux4SAM/Sama5d2XplainedMainPage >> >> I admit that it's not copleted, but you'll have an idea here as well: >> http://www.at91.com/linux4sam/bin/view/Linux4SAM/Sama5d2XplainedMainPage Yes, I was meaning: http://www.at91.com/linux4sam/bin/view/Linux4SAM/LinuxKernel#Tags > Both URLs are the same, are you sure it's the correct link?

Yes, we lack this kind of important information. It's scattered on some messages on the arm-linux-kernel mailing-list as we tend to publish pretty early in our work process (Cf. the new ADC driver by Ludovic). I don't promise but we will try to enhance this aspect in the near future... ;-) Thanks for your work and your feedback. Bye, -- Nicolas Ferre
