Re: [U-Boot] SPL variant of sunxi nand module

29 Dec 2018


      Hi,
Its just to remind sunxi_nand_spl.c is still broken. (And probably has 
been for a couple releases or so).
I'm unable to fix it myself (other than reverting the mentioned commit 
locally.)
Thank you,
Regards,
Nikolai

Hi again,
The following commit (titled "use PIO instead of DMA") apparently broke
actual reading of nand pages in SPL at least for A20:
http://git.denx.de/?p=u-boot.git;a=commit;h=6ddbb1e936c78cdef1e7395039fa7020...
Instead of reading page contents, non-dma (current) version just feeds
zeroes here.
Tested on A20-olinuxino-micro with a Hynix 4GB nand chip.
It'd be nice to somehow fix it back eventually :)
Other than that, nand boot seems usable (with added necessary chip id).
Thank you,
Regards,
Nikolai
