[BPI-R4] No NVME and bad NAND on BPI-R4 8GB version

[ericwoud (Eric W.)]

I meant, booting 8gb ddr board from emmc, I guess it would also be possible to use bl2 build for 4gb ddr, since emmc and sdmmc driver is the same…

Have not tried it,but image can be 4gb…if needed you can replace bl2 on emmc easily like for sdmmc

Does anyone know if any hardware changes have been made to the BPI-R4 8GB version besides the added RAM?

looks like NAND is also larger, capacity-wise, for me it’s W25N04KVZEIR, but I’m on v1.1 of the board

My unit came with W25N02KVZEIR. Are you sure of the memory model?

My bad, it is really the N02K

Thanks @Dot_Brian. I did use some older bl2 and fip images, but they were the same exact ones I use on my BPI-R4 4GB version. On that one the NVME works flawlessly in u-boot (and the kernel), so I was expecting it would work here too, assuming no changes to HW besides the RAM. I also noticed the 4GB limit on my uboot but thought I’d shelf then for now.

If you don’t mind and have an NVME device plugged in, could you please check if it is suppoerted in uboot on your board, perhaps by running pci enum; nvme scan; nvme info.

Since the only hardware change is RAM, I expected NVMe to work similarly
