如何使用STLink-V2将原始固件重新上传到ST25R3911B-DISCO

嗨伊万，
这里不需要调试器，只需按照用户手册：
在UM2177第2.3章中
/external-link.jspa?url=http%3A%2F%2Fwww.st.com%2Fcontent%2Fst_com%2Fen%2Fproducts%2Fembedded-software%2Fst25-nfc-rfid-software%2Fstsw-st25r001.html
 您将找到如何从GUI（不使用SWD / JTAG）调试器更新电路板的说明，即使当前固件不与GUI通信（使用系统加载器DFU模式）。
我们知道，例如这个适配器工作：
https://www.segger.com/products/debug-probes/j-link/accessories/adapters/9-pin-cortex-m-adapter/
 
也许您在MCU上的当前应用程序与调试引脚混淆，您可以尝试在连接调试器之前将STM32置于引导加载程序模式：按下Boot按钮，按住它，按Reset按钮，释放它，然后释放Boot按钮。现在您可以再次连接调试器。

Hi Ivan,
no need for debugger here, just follow the User Manual:

In UM2177 chapter 2.3 of
/external-link.jspa?url=http%3A%2F%2Fwww.st.com%2Fcontent%2Fst_com%2Fen%2Fproducts%2Fembedded-software%2Fst25-nfc-rfid-software%2Fstsw-st25r001.html
you will find a description how to update the board from the GUI (without using an SWD/JTAG) debugger even if the current firmware does not communicate with the GUI (Using the System Loader DFU mode).

We know that e.g. this adapter works:


https://www.segger.com/products/debug-probes/j-link/accessories/adapters/9-pin-cortex-m-adapter/

Maybe your current application on the MCU messes with the debug pins, you could try to put the STM32 into bootloader mode before connecting with the debugger: Press Boot button, keep it pressed, Press Reset button, release it, then release Boot button. Now you might be able to connect with debugger again.

谢谢。
请给我一个正确的原理图。
