sdmmc_error_data_crc_fail 错误解析 1. 错误含义 sdmmc_error_data_crc_fail 错误表示在SD/MMC卡的数据传输过程中,循环冗余校验(CRC)失败。CRC是一种用于检测数据传输或存储中是否出现错误的技术。当接收端计算出的CRC值与发送端提供的CRC值不匹配时,就会触发此错误。

运行代码后,写数据正常,读数据在发送CMD18后,寄存器ERROR_INTR_STS内容为0b01100000.从TRM中可以看出错误如下: 寄存器NORMAL_INTR_STS内容为0b1000000000100001对应内容如下: 如果我将读取数据大小设置为一个block(512), 是通过CMD17设置参数的,则可以正常读取。 请问:读取数据时的错误DATA_CRC,DATA_ENDBIT可能是哪...
