MMC standby issue for WiFI on imx6dl board

mrleo · ‎11-18-2014

Hi,all

I debug rtl8723 sdio module in android 4.4.2 system on on imx6dl board,I found that if system enter standby,after a while,resume the system.

It can not enable the wifi.

I think this is mmc standby issue about sd_write32 error.

What should I do to solve this problem?

Below are error messages:

Hi mrleo!

I also want to debug rtl8723 sdio module on I.MX6Q.

Are there some schematics and programs can give some helps？

Thank you very much!

Hi，all

Wifi rtl8723as no hardware cd detect,how to wake up sdio?

When I enabled wifi,after suspend,resume the system,wifi driver can wake up sdio.

If not enabled wifi,after suspend,resume the system,enabled wifi,will be not ok.

I think it is not found sdio.

How to detect wifi sdio?

Thanks,

Leo

Hi all,

I found that if not enable the wifi or connected the wifi,enter suspend,later resume the system. The sdio is not detected.

like belwo:

cat /sys/kernel/debug/mmc2/ios

clock: 400000 Hz

vdd: 21 (3.3 ~ 3.4 V)

bus mode: 1 (open drain)

chip select: 0 (don't care)

power mode: 2 (on)

bus width: 0 (1 bits)

timing spec: 0 (legacy)

Thanks,

Leo
