imx6solo SDIO1 port abnormal

[garyyin]

linux 3.10.45

a broadcom wifi module is connected to SDIO1

When I am measuring the wifi network speed, using iperf. The kernel driver crash after about testing for 4 minutes as following:

The speed after that is alway 0.00 bits/sec.

This problem occurs randomly, not everytime.

According to our wifi module provider's document, they tested the same wifi driver souce code on other android based board(not imx6 chip, linux 3.0.35), it's OK.

Hi Gary

linux 3.10.45 is not supported by nxp in its bsp releases, it may be recommended to apply

for updated driver on vendor support link

Best regards

They tell me that no patch for specific linux kernel.

[igorpadykov]

please try with official nxp releases on

i.MX 6 Series Software and Development Tool|NXP

I tested using L3.14.28 today, the problem occured again, but it recovered quickly.

Following all ok.

I tested under your offical release L3.14.28, it's very stable, no crash.
