STM32H743开发板移植micropython并外扩32M的SQPI flash和32M的SDRAM源码

编译了一下发现如下错误：In function `storage_write_blocks': storage.c:(.text.storage_write_blocks+0x26): undefined reference to `spi_bdev_writeblocks' build-STM32H743I/storage.o: In function `storage_read_blocks': storage.c:(.text.storage_read_blocks+0x2a): undefined reference to `spi_bdev_readblocks'
