I have a new iMX6SL custom board with WiLink8 chipset. The chipset has some features of SDIO 3.0 support and the I/O is 1.8v or (SDR25). I used the
mainline kernel 3.13, 3.19 and the Freescale (fsl-yocto-3.10.53-1.1.0), all of them detects the wifi. All of them uses 3.3v voltage signal.
clock: 50000000 Hz
actual clock: 49500000 Hz
vdd: 7 (1.65 - 1.95 V)
bus mode: 2 (push-pull)
chip select: 0 (don't care)
power mode: 2 (on)
bus width: 2 (4 bits)
timing spec: 2 (sd high-speed)
--->>> signal voltage: 0 (3.30 V) <---> it should be 1.8v
I would like to know if there's any available patches out there that I
could use in order support SDR25?.
