Honeycomb not recognising M.2 NVMe device

NXP LX2160
1

Hi all,

So, my Honeycomb LX2 finally beat the chip supply crisis, and I’ve assembled it into a mostly working system. Boot from MMC works fine, but I can’t seem to access to the attached NVME drive.

Super grateful in advance for any advice :-).

Background

When attempting to copy a boot image from uboot I get:

=> load mmc 0:1 0xa4000000 ubuntu-core.img
440401920 bytes read in 19192 ms (21.9 MiB/s)
=> nvme scan
=> nvme write 0xa4000000 0 0xd2000

nvme write: device 0 block # 0, count 860160 ... -19 blocks written: ERROR
=>

Attempting to access the NVMe from within Linux (booted from MMC) gives similar results:

[  135.741600] nvme nvme0: Device not ready; aborting reset
[  135.762189] blk_update_request: I/O error, dev nvme0n1, sector 488396928 op 0x0:(READ) flags 0x80700 phys_seg 1 prio class 0

# Questions

  • Before I try another drive, are there any particular compatibility requirements I should be paying attention to?
  • Are there any DIP switches or other configuration I may have missed required to make NVMe work?
  • Any other ideas?

Reference info:

The M.2 drive I’m using is: Crucial P5 250GB M.2 2280SS

The Linux OS image I’m using is: lx2160acex7_2000_700_3200_8_5_2-bc46e34.img

Can you test a SystemReady edk2 image from here SolidRun Images and see if it is able to access you nvme device?

Hi!

Thanks for helping :-); I’ll be honest, I’m not an expert from the UEFI prompt (give me a Sparcstation with an OpenBoot prompt and I’m away, but now I’m showing my age…,) but I’ve given it a go and I am thinking the short answer is ‘no’.

This is the output from the devices command:

I assume if UEFI had a driver/was able to access it as a block device then it would appear in this list?

That said, the pci command does show the drive:

Shell> pci
   Seg  Bus  Dev  Func
   ---  ---  ---  ----
    02   00   00    00 ==> Bridge Device - PCI/PCI bridge
             Vendor 1957 Device 8D80 Prog Interface 0
    02   01   00    00 ==> Mass Storage Controller - Non-volatile memory subsystem
             Vendor 1344 Device 5405 Prog Interface 2

(Vendor 1344 is Micron aka Crucial, so pretty sure that’s the right device. At least this reassures me I plugged it in the right way round ;-).)

Incidentally I just bought the 1TB drive in the same series and discovered that it does not work with the Honeycomb board :grimacing:

CT1000P5SSD8 is the exact model I have.

Ahh, this is good information to have.

For the timebeing I’ve worked around it by using a SATA drive (I have stuff to do and need to keep making progress…), but good to know I shouldn’t assume the M.2 drive itself is dead.

Sorry to hear about the incompatibility. I have not tested any Crucial drives personally. If you have time I can build a debug firmware that may hopefully provide more information on what the incompatibility issue is.

7

I need to build/install a new OS image anyway (turns out Docker can’t run with the SolidRun provided images anyway because the kernel’s not built with required iptables/NAT options - boring story) so my time with a screwdriver and swapping SD cards isn’t quite over yet - so sure, I’d be more than happy to help if I can.

In case you are shopping for another, I had better luck with:
Disk model: Samsung SSD 970 EVO Plus 500GB
I’m able to boot from eMMC to use the M2 card as the root partition.
