针对你提到的mmc error: the cmd index is 1, ret is -110错误,我们可以从以下几个方面进行分析和解答: 1. 错误上下文 这个错误通常出现在尝试从MMC(MultiMediaCard)设备(如SD卡或eMMC)启动时。mmc error: the cmd index is 1, ret is -110表明在发送MMC命令时遇到了问题,具体是命令索引为1的命令执行失败...

发送CMD3指令,SET_RELATIVE_ADDR 设置该mmc card的关联地址为card->rca,也就是0x0001 完成之后,该MMC card进入standby模式。 mmc_send_csd 发送CMD9指令,MMC_SEND_CSD 要求mmc card发送csd寄存器,存储到card->raw_csd中,也就是原始的csd寄存器的值。 此时mmc card还是处于standby state mmc_select_card & mm...
eMMC 5.1+ supports HS400 Enhances Strobe mode without the need for tuning procedure. The flow is as following: - set HS_TIMIMG (Highspeed) - Host change freq to <= 52Mhz - set the bus width to Enhanced strobe and DDR8Bit(CMD6), EXT_CSD[183] = 0x86 instead of 0x80 - set HS_...
