Replace the ad-hoc erase operation implementation with a simple spi_mem_op implementation of the same functionality. This is a minor optimization and removal of the ad-hoc code. This however also changes the behavior of the execution of the erase opcode from two separate transfer requests to th...
模块配置介绍 目前有两种方法进行引脚配置:sys_config和平台头文件。 这两种方法选其中一种使用即可,在没有sys_config文件配置时,默认使用平台头文件。当检测到有sys_config文件并有相关关键字时,自动切换为该方法。 sys_config文件引脚配置说明 引脚配置在source/project/方案/configs/sys_config.fex [spi1] spi1_...
