NVME problems

[mamboman777]

I’ve the same issue with the Intel 660p. Was using it as my root partition for ca. 1 month without issues. It was still working yesterday evening before I shut it down (suspend is not working with a nvme installed), and after restart this afternoon the OS didn’t came up. So I took a last known working version from microSD and it booted very slowly. At the end it shows me that the nvme isn’t mounted, so I checked dmesg and found this:

Code:

nvme nvme0: Device not ready; aborting initialization, CSTS=0x0
nvme nvme0: Removing after probe failure status: -19

It is also responsible for the long boot time (there is a 30sec delay before those lines are listed).

I already opened the case and checked the cable and nvme connection in the adapter. I also reflashed the latest u-boot to both spi and eMMC, but it shows no success.

Any idea what might be the cause for this problem?

I do not know what causes this problem, but I know how to get out of it...or at least what works for me.  I do not remember where I got the SPI flash, but I have one that always wakes the drive up.  I suspect the problem is something with the way that the newer U-Boot loads the 660P that makes it get to an un-reachable state, but I can't figure out what causes it to be un-reachable  Maybe something to do with APST? Like I said, I don't really know.  The way I get out of it is boot to the SD card and flash one of the SPI flash's that preceeded the main-line U-Boot SPI flash.  PM me and I can get the file to you.
