Are you using our baseboards?
Could you take a picture?

Yes, I'm using the baseboard MB-JD4-RV11091126. I'll take a picture later.

Edit:

I can build the firmware with the thunder boot option and boot successfully after flashing. Everything boots and loads as intended.
./build.sh device/rockchip/rv1126_rv1109/aio-rv1126-jd4-BE-45-tb-v11.mk
./build.sh

I cannot, however, build and flash the normal firmware:
./build.sh device/rockchip/rv1126_rv1109/aio-rv1126-jd4-BE-45.mk
./build.sh

Can you run without connecting to your peripherals and leaving only the core board and the backplane?

I compile and burn the device and it works fine.

Maybe you can package the firmware for burning.

1. ./build.sh updateimg
   
2. upgrade_tool ef xxx.img
   
3. upgrade_tool uf xxx.img

I disconnected everything except DEBUG connector but board still boots into recovery mode.

Didn't help, still same problem.

I have the same kernel commit id:

Found the problem:
I had disabled the FIQ debugger in the device tree:

1. &fiq_debugger {
   
2.         status = "disabled";
   
3. };

Copy the code

When fiq debugger was enabled the board boots normally.
I don't know why the board boots into recovery mode when the FIQ debugger is disabled.

I'll confirm the problem first
