Hello,

Finally I managed to have my remote processor module working!

I shared the source code along several information on this github page:
https://github.com/nvitya/rk3506-mcu

Two issues are still open, and I'm seeking help for solve these:

1. Hot-swapping the MCU FW:

Once the MCU code is ...

Hello,

Thank you for your answer.
I managed to compile and install the AMP version of your image.
I got indeed "[HAL INFO] Hello RK3506 mcu" on the UART4 at u-boot time.
But nothing more. And also one A7 CPU less, it seems that one A7 CPU is also reserved for the AMP system.

Developing an MCU ...

Hi,

I would like to run some special bare-metal Firwmare on the Cortex-M0 MCU. I did not find proper information how to load and start MCU FW so I started developing remote processor driver for the RK3506 MCU.

I've created a project on the github here:

When this ...

Yes, the situation improved, someone uploaded the rk3506 TRM:

Not that perfekt, but much better as nothing.
What I also noticed, in the Luckfox SDK there is a HAL library, here in hal/lib/CMSIS/Device/RK3506/Include/rk3506.h you will find ...

Hi,

On the Milk-V Duo I can develop bare metal software on the small core using a JTAG debugger.
I would like to do the same on the rk3506 (Luckfox Lyra Plus). So using openocd and a SWD debugger I would like to contact to the Cortex-M0 core, upload the software from the ide, and debug from the IDE ...
