The eMMC with HS400 mode didn't work in customer board. There was problem on MMC_PollingCardStatusBusy for HS400, but it works for HS200. Do we have HS400 test examples for RT685? Is there any guide for this case?
Hi @shaozhongliangs ,
There is no EMMC demo in RT1170 SDK, but you can refer to RT500 SDK(mmccard_fatfs), this is HS400 demo example, the SDHC IP is same.
