Bananapi BPI-R4 nvme reboot vs cold start

For Developers
1

Does anyone have the same problem that an NVMe is no longer recognized after a reboot on the BPI-R4, but after a cold start the recognition works.

OpenWrt Snapshot - Kernel-Version 6.6.32

Did you try to look for solution here?

thanks for the info, I saw that post, yes.
But I didnt compiled the image by myself. I downloaded the image from OpenWrt Selector.

you don't need to recompile the entire image, just to make u-boot choose this option instead of NAND or EMMC.
What is your output of fw_printenv?

Thats the output:

~# fw_printenv

Some more information:
I installed and boot the Image from SD-Card.
The NVMe is only an additonal volume for using container instances and other applications

~: dmesg | grep -i u-boot

It seems that is a problem with the model of the NVMe.
Tested with another NVMe: Magix SSD 256GB M.2 Gen3x4 PCIe X-EVO
