Samsung NVMe M.2 SSD 970 EVO Plus fails to attach on VisionFive 2
(JH7110 SoC) board
I just got a Samsung NVMe M.2 SSD 970 EVO Plus to test the recently added
support for PCIE devices to JH7110 SoC but it has not been working correctly
with this disk.
The behavior I'm observing is a little erratic, the NVMe disk only attached
correctly like in 1 of 10 or more boot attempts.
Only a couple of times worked OK, but most of the times one of the following
is observed:
- No nvme0 device detected during autoconf phase, nothing related to the
device shows up in dmesg and no sd0 device is attached. When this
happens the board boots OK and SD/MMC devices are detected and attached.
- nvme0 device is detected during autoconf, sd0 device attaches but boot
hangs. Looks like kernel never reaches diskconf() or if it reached it
something is preventing the kernel from print the typical message:
root on sd0a (062aeb9d33543517.a) swap on sd0b dump on sd0b
- nvme0 device appears in dmesg but the device fails to attach with the
following message:
nvme0 at pci3 dev 0 function 0 "Samsung SM981/PM981 NVMe" rev 0x00: unable to
map registers
- To workaround this I'm just booting the kernel with -c option to disable
nvme driver in UKC and proceed with the boot.
I tried to debug more by building a kernel with DEBUG option set to gather more
info but unfortunately if I boot such a kernel my board gets stuck very early
in the boot process just after printing how much real memory is available.
I'm more than happy to provide more info if required or to try patches if
that helps to troubleshoot the issue.
Thanks.
Miguel.
