疑似有问题,QSPI的CLK引脚居然和BOOT1引脚共享PB2,开发板手册上的那一段我没看懂,哪位帮我看一下是不是这个影响了QSPI
Note that QSPI_CLK (port PB2) is sampled by the STM32F412ZGT6 at start-up as the
BOOT1 bit. If necessary, the user can set the BOOT1 state by fitting one of the resistors
R100 or R104. By default R100 and R104 are not fitted. Refer to Section 6.7: Boot options
for more details.
Limitations: The Quad-SPI memory is not working when the STM32 is supplied with 2 V.
