dear all,
I want to used mmc2(SD card) on am335x, now mmc0 can work, but how to support mmc2 on the SDK 7.0? how to setup dts?
I have see mmc3 setting on am335x-evm.dts, but it can't work. maybe need to setup other?
now my mmc3 ios:
clock: 400000 Hz
vdd: 15 (2.7 ~ 2.8 V)
bus mode: 2 (push-pull)
chip select: 0 (don't care)
power mode: 2 (on)
bus width: 0 (1 bits)
timing spec: 0 (legacy)
signal voltage: 0 (3.30 V)
it's clock and bus width isn't right, how to set clock and bus width?
Thank!
