GD32F103RC burning problem [Copy link]

When burning GD32F103RC, use J-Flash to burn. After burning once with GD32F103RC as the chip model, choose STM32F103RC for decryption, and then burn the program without encryption. After burning, it is found that the program is abnormal. After changing to a new MCU, continue to choose STM32F103RC model to burn without problems. Will there be problems when choosing GD32F103RC to burn for the first time? (The program uses ST library)

I have been using the GD32 burning option and it has been working fine. I also use the gd32 library for programming.

Solved. When I used J-Flash to burn and encrypt, I selected GD32F103. When I decrypted, I selected STM32F103. This caused the problem when I burned the program again. Solution: Use J-Flash to select the chip model STM32F103 to perform an encryption and decryption operation. There will be no abnormality when burning the program again.
