Linux/PROCESSOR-SDK-AM335X: Issue with WiFi dongle

Tesla Yu

Tool/software: Linux

I have met this backtrace when using wifi dongle AR9271, and I have already merged patch from https://e2e.ti.com/support/arm/sitara_arm/f/791/t/385033 What's wrong? could anybody can help? I am using SDK 1.0.0.3 with kernel 3.14.43. AR9271‘s driver is cfg80211 in kernel.

Thanks!

Hi,

1. You could check in the latest SDK
2. Does the warning come on screen or does the WiFi functionality break ?
3. Can you check if this patch helps: www.spinics.net/.../msg108191.html

Hi,

You can just refer to the above piece of code(musb_h_tx_flush_fifo() function) in the latest SDK and take the fix if it is available. I think there was some change w.r.t to WARN and delay. Can you check the latest SDK for it.
