Hello,
I am new to dual core processors. I was working on both cm4 and cm7. My main core was cm7. I accidentally disabled the cm7 core on Stm32CubeProgrammer and now I cannot connect to the board. Power comes and goes instantly. (I normally use STLK to connect the board.) What can I do to make my board work again?

Hello,
You need to select the access port number 3 in STM32CubeProgrammer before to connect:

Connect to the device over access port 3 to recover the device. This is a setting on the right side of STM32CubeProgrammer.

I can’t see access port 3 on my STM32CubeProgrammer. There is only access port 0 on there. Also the target voltage goes down to zero. I think I need another solution.

What is the CubeProgrammer version are you using?

I solved the problem. It was not about the CubeProgrammer version. When I only use STLK input, the target voltage goes to zero and I could only see the access port 0. I used both STLK and POWER inputs and then I could see the access port 3 and enabled the cm7.
