> if the fix also exposes the NVMe as drive This is a feature I really want too, but may be a bit more difficult to accomplish. The MSD mode works by uploading a small stub program (provided by Rockchip) to the RK3588 which exposes the eMMC over USB (as well as some other features, like the ability to access raw RAM). Accessing the NVMe drive requires support for the PCIe+NVMe protocols -- which the stub program doesn't have. Though, U-Boot supports NVMe+PCIe and (though I haven't confirmed) USB in device mode. The way to access the NVMe drive might be to interrupt the RK1 bootloader and run the

ums 0 nvme 0

command.
