dd？I have not tried this method, generally I use "rockusb 0 mmc 0", and then use linux upgrade_tool to flash uboot.img.

Can you tell me, do rockusb upgrade only emmc, or I can use it to upgrade u-boot in SD card too?
On my plate now I must not touch EMMC, because of production is here... I afraid to brake it... Linux upgrade tool docs are in Chinese and I can't read this.

We clearly see that there is no power to devices connected via USB, and if you power the USB device from the outside, it is seen in U-BOOT. In Linux power works fine. Tested on revision boards 1.0 and 1.1 and on different versions of SDK - 1.0.0 and 1.0.1.

NVME is not working in U-BOOT too (n o power. I tried to compare linux DTS and u-boot DTS and found that there is no powers applied for USB or NVME. Now I try to enable power due to kernel DTS, but it is not working now
