Seeing an interesting behaviour.

This NVME to USB disk gets detected 100% of the time when its plugged in while usb is starting. So after the usb controller is initialized and ready but before the controller is scanned for devices.

It seems like the device isn't reset correctly on controller power up and goes in an error state.

Hi,

...

I am trying to boot OS via USB3.0 ports on RK3399 base RockPro64. U-boot is failing to detect the drive in the USB3.0 port.

If I boot linux through other mediums the drive is detected and works fine. Can anyone please help me figure out the issue?

Can you share the version of U-Boot you're using?

I have tried 2023.1, 2023.10 , 2024.01-rc2

An interesting finding, if I connect the same disk via a bus-powered (no external power) USB3.0 hub the disk gets detected 100% of the time. Directly connecting the same disk to the same USB3.0 port and U-boot fails to find it. Connecting on a USB2.0 port works too.

Regards,
