Hi Simon, it took me some time to come back to this issue, but I was able to enable the debug messages on drivers/nvme/nvme.c.
This is what I got when running the nvme scan command
U-Boot> pci BusDevFun VendorId DeviceId Device Class Sub-Class _____________________________________________________________ 00.00.00 0x14e4 0x2711 Bridge device 0x04 01.00.00 0x1c5c 0x174a Mass storage controller 0x08 U-Boot> nvme info U-Boot> nvme scan Cannot set queue count (err=-110) Unable to setup I/O queues(err=-110) Failed to probe 'nvme#0': err=-110 U-Boot>
I'm reporting as soon as I got the messages, but I'll continue investigating.
Can you check if the device has PCI bus master enabled?

Hi Simon, I enabled the next four variables
CONFIG_NVME_PCI=y CONFIG_NVME=y CONFIG_CMD_NVME=y CONFIG_PCI=y
how different is CONFIG_NVME_PCI from NVME_PCI, I took the latter value
from several configs files in u-boot repo and from [1]
I just left off the CONFIG as they all have that. This looks right to me. Assuming that the NVMe controller appears in 'dm tree' perhaps you can enable debugging in the driver and see why it is not working?

I compiled u-boot version 2023-07 and boot it on a RPi CM4 using a
PCIe M.2
NVMe drive, but it doesn't appear to be working.
Once u-boot has started and boot successfully it recognizes the PCIe
device
giving me the next output
U-Boot> pci BusDevFun VendorId DeviceId Device Class Sub-Class _____________________________________________________________ 00.00.00 0x14e4 0x2711 Bridge device 0x04 01.00.00 0x1c5c 0x174a Mass storage controller 0x08
but when trying to use the nvme scan and nvme info there is not
output.
NVMe drive has two partitions 1st is a FAT partition, and 2nd is a
EXT4
partition, the RPi firmware recognizes the FAT partition and u-boot
boot
correctly.
I don't know if this worked before, but I saw in the mailing list
that
there could be already support for other ARM64 boards.
Is NVME_PCI enabled?
