i.MX8MM eMMC sd3 clk dse en slew rate setting

The above mentioned pad control settings are not described in the reference manual. Why and how can we test / trim these settings?


Re: i.MX8MM eMMC sd3 clk dse en slew rate setting

Hello @NLFOHE 

Hope you are doing very well.


Actually, that pad is under the register's name: IOMUXC_SW_PAD_CTL_PAD_NAND_WE_B.

Mux mode register should be configured as uSDHC3 (IOMUXC_SW_MUX_CTL_PAD_NAND_WE_B):
