I'm pretty SN850X PCIe 4 devices don't work at GEN2 and are incompatible, please check that it works under Linux. If not it's not going to work as a boot device.

If I remove the Hat and connect SN850X via USB with a pcie/usb adapter, rpi5 bootloader runs correctly from USB and rpi5 works fine. I have read that the latest version of pieeprom has introduced compatibility with the WD SN350, SN550 and SN580 series. Could this be a potential solution?

To add more detail to my previous comment the question is does NVMe work natively under Linux when the Pi is booted from SD i.e. can you mount the drive, copy files, run dd tests etc.

If a USB adapter is added then the NVMe is talking to a PCIe interface inside the adapter and not the BCM2712 PCIe RC. Linux now just sees a USB-MSD device with some flash memory.

If you want to try a more recent bootloader then flash RPi OS to a spare SD-card, run "sudo rpi-update" then check the native NVMe behavior. There are some improvements for timing and switches.

However, there are some WD Black devices which only work at Gen4 and if these don't work natively from Linux then they definitely aren't going to work with the bootloader.

Hi timg236, Folllowing your steps:

• Format nvme to exFat.

• Connect SN850X by Pcie (Hat) to rpi5.

• Use microSD to boot rpi5.

• Rpi5 runs, detects nvme and I mount it.

  

• Copy files ok.

• Use "SD card copy" again for copying OS from microSD to nvme (Finished ok).
• Config boot order.
• Config config.txt.
• Shutdown rpi5, remove microSD and boot.

But... same error, rpi5 can't boot from WD_Black SN850X. Any other suggestions?

Thanks a lots
