iMX6 SDR12 Suport

Hello All,

 

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?.

 

Regards,
