OK, Every time I download the program to the MCU, there is a window like this.
I have used pio update and the JLink has been update to V6.92.
Thank you for your help!
If I not click the OK, downloading will still go on and after complete, the window will disappear automatically
Hm affter searching around a bit I stumbled upon this article (https://blog.csdn.net/qlexcel/article/details/85711693) where it says that it might have detected a mismatch between two installed JLink driver of firmware versions. So maybe since you’ve installed V.6.92 but PIO is using V6.88 the V6.88 program thinks that the firmware on the JLink is “defective”. Could maybe be solved by either upgrading the PIO JLink version (replace files in C:\Users\<user>\.platformio\packages\tool-jlink with the one from latest version, but don’t change .piopm or package.json file) or downgrade the globally installed JLink driver version.
