Subject: ath10k_sdio: failed to write to address
Date: Fri, 17 Sep 2021 14:37:52 -0300	[thread overview]
Message-ID: <CAOMZO5BROh1wET6vcif_8Q+aMQUFqRMP5uttBBLV8nJnbOv8rg@mail.gmail.com> (raw)

Hi,

On an i.MX7-based board, I see the following "failed to write to address" error:

ath10k_sdio mmc2:0001:1: qca9377 hw1.1 sdio target 0x05020001 chip_id
0x00000000 sub 0000:0000

ath10k_sdio mmc2:0001:1: failed to write skb to 0x12ff5 asynchronously: -84

The wifi is functional despite the errors.

I tried applying Erik's patch:
https://github.com/erstrom/linux-ath/commit/6507fd8df431e1d1f1ea344224956387dc1d35aa

and the one from Niklas:
https://github.com/erstrom/linux-ath/commit/4e794a12fa89e353e38528d1ada5d86f19672c3c

but it did not help.

Does anyone have any suggestions as to how to fix it?

Thanks,

Fabio Estevam
