From: "Ying-Chun Liu (PaulLiu)" <paul....@linaro.org> The eMMC device on imx8mm-cl-iot-gate seems not support hs400. When booting 6.1.0 kernel we got the following error.
mmc2: mmc_select_hs400es failed, error -110 mmc2: error -110 whilst initialising MMC card Add no-mmc-hs400 to mmc2 node solves the problem. Ying-Chun Liu (PaulLiu) (1): arch: arm: dts: imx8mm-cl-iot-gate.dts: add no-mmc-hs400 to mmc2 arch/arm/dts/imx8mm-cl-iot-gate.dts | 1 + 1 file changed, 1 insertion(+) -- 2.45.2
