GP10-NRST脚 可以做普通IO，你用CubeMx配置下。


更多细节可以看看参考手册的相关描述。




9.3.16 Using PG10 as GPIO

PG10 may be used as reset pin (NRST) or as a GPIO. Depending on the NRST_MODE bits
in the user option byte, it switches to those mode:


1、Reset input/output: default at power-on reset or after option bytes loading
NRST_MODE = 3
2、 Reset input only: after option bytes loading NRST_MODE = 1
3、GPIO PG10 mode: after option bytes loading NRST_MODE = 2

从手册上可以看出，通过option byte 可以更改它的功能。
