Evaluation Report 3 of the CMS32M6534E+CMS130S040P56B Drill/Wrench Development Board: Help: Hardware not found [Copy link]

 

1 After the last test, the hardware could not be detected, so I suspected that it was a problem with the downloader. So I bought a new downloader based on the downloader that my friend successfully tested online. And I also bought a motor.

as the picture shows

You can see that the light on the circuit board is on, indicating that there is no problem with the wiring.

2 Software Connection

Open keil5, connect the circuit board, and it cannot be detected, as shown in the figure below.

Tip: swd/jtag communication failure.

I searched online for the cause of the problem, and a friend said:

I still can't find it after setting it this way.

Help: Please give me some advice. Thank you very much.

Can the firmware in the original board still run?

I just can't find the board right now. I've used two downloaders and only saw the chip once, so I don't know if it can run.

Is there any firmware in the board when it leaves the factory? It can be determined whether the board is broken.

The board is locked and can only be unlocked by using another programmer

My intuition is not broken, I don't know why

I have changed two burners and bought an official one to try.
