Hello, is there a ubi image with u-boot + fdt (stock image) that I can flash to my BPI-RV2 with an external flasher? I somehow made u-boot not start correctly when changing partition 3 (fdt/rootfs) to run Gentoo.
btw should I bridge these pads in red and use jtag from gpio header? I also have xgecu t48 and ch341a.
You can try this image
Yes, but the jtag and pcie functions are reused, so some changes need to be made
Okay thanks! I’ll try the image now. What changes do you mean, is there something I can do?

Seems like the UBI image is in 0x0 on my original messed up flash and yours is in 0x20000

I used ch341a to flash nand chip directly.
