Hi
I am wifi testing with my custorm board.
wifi module is connected to usdhc1 and using 1.8V.
but the information is not correct please see below.
root@imx8mp-lpddr4-evk:~# cat /sys/kernel/debug/mmc1/ios
clock:0 Hz
vdd:0 (invalid)
bus mode:2 (push-pull)
chip select:0 (don't care)
power mode:0 (off)
bus width:0 (1 bits)
timing spec:0 (legacy)
signal voltage:0 (3.30 V)
driver type:0 (driver type B)
yocto version is 6.1.22_2.0.0 and dtb file is imx8mp-evk-usdhc1-m2
how can fix it
Best Regards
As you can see the regulator voltage is 3.3V, you could change it to 1.8V.
