Hi @jadellamorte 

Would suggest check the DTS and Driver. Refer to the usdhc2 node of 8mn (linux-imx/imx8mm-evk.dtsi at lf-6.1.y · nxp-imx/linux-imx · GitHub) and these CONFIG_MMC, CONFIG_MMC_BLOCK, CONFIG_EXT4_FS enabled or not.

If there is /dev/mmcblk1 node, then check its driver.

 

Best regards

Harvey

Thanks for the reply! but I found the problem I copy and pasted a usdhc2 regulator of the imx8mn-ddr-evk device tree, and based of schematic it was not needed and causing problems.
