新购买的stm32f412 discovery的QSPI例程出错！

         本人刚购买的stm32f412 discovery,所有的QSPI例程均是直接跳入error_handler,led3指示报错；仔细检查后没有发现代码问题，只是与QSPI芯片的通信完全没有，无论是写还是读，不知道是不是硬件问题，还是官方例程有错，有没有坛友用过的有相同的问题。

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.

QSPI芯片坏掉的可能性不大，哪位能解释一下和BOOT1复用是啥意思。
