Hi, On a imx7s-warp board (sdhci-esdhc-imx.c driver) running 4.12-rc1 the following mmc1 error message is seen: [ 1.796192] mmc1: mmc_select_hs200 failed, error -74 [ 1.810220] mmc1: new MMC card at address 0001 [ 1.823066] mmcblk1: mmc1:0001 V10008 7.05 GiB [ 1.834155] mmcblk1boot0: mmc1:0001 V10008 partition 1 4.00 MiB [ 1.841608] mmcblk1boot1: mmc1:0001 V10008 partition 2 4.00 MiB [ 1.848971] mmcblk1rpmb: mmc1:0001 V10008 partition 3 4.00 MiB [ 1.859576] mmcblk1: p1 p2 The rootfs can be mounted correctly from eMMC though. What is the proper way to fix the 'mmc_select_hs200 failed' error message?
