If it is necessary to override the configured flash size at runtime, is is possible to set thechip_sizemember ofg_rom_flashchipstructure. This size is used byspi_flash_*functions (in both software & ROM) for bounds checking. 如果需要在运行时修改配置的 flash 大小,则可以设置g_rom_flashchi...

注意:所有SPI相关的API都不能在中断服务函数或上下文切换期间使用,因为SPI相关的API都调用了互斥量,可能会造成系统错误 SPI 调用#include "driver/spi_master.h"或#include "driver/spi_slave.h"
