I'm sorry, I accidentally sent the problem out, when I was not finished.

Someone told me to disable JTAG, I did it, but ST-Link still did not work.

But JLink is still working in JTAG mode.

I don't konw why~

Do I need other code to disable JTAG?

(In addition I used the freeRTOS, and this related?)

Please help me, thank you.

I wish you happiness.

Sorry for my english.
