Hi All,

We are using CYW43012 chipset with the following details:

Firmware version:

1.21 RC0.0
wl0: Feb 21 2022 07:19:28 version 13.10.271.283 (211da63 CY) FWID 01-18f4ac2

 

Driver Version:

Backported Linux Version v4.14.77-kong-RTM-rc8-0-ged6fa18

 

We have observed that after certain time, we are seeing SDIO -110 error as follows:

This issue is frequently reproducible and any need asap is deeply appreciated.

Attached the complete log file for your reference.

Hi @raks_99 

Increasing BRCMF_SDIO_MAX_ACCESS_ERRORS value didn't help. We disabled CONFIG_PM_SLEEP to avoid SDIO sleep and wake up cycles and found that the issue was not able to be reproduced. For now we are proceeding with that as a stop gap solution as we are pressed on time for our production.

Regards,

Rupesh.

Hi @rupesh_theatro ,

Let me check for this issue.

As one possible workaround, can you try increasing the value of the macro "BRCMF_SDIO_MAX_ACCESS_ERRORS" in "sdio.c" file from 20 (default ) to 100.

How do you restore the module after this issue occurs? by reloading the drivers?

Thanks

No, we are currently rebooting our device for it to recover.

 

On a high level, what do you suspect to be the reason for this behavior?

I suspected that it could be due to SDIO access timeout errors. But in that case, it should have auto recovered. 

Is this a regression in some newer versions of the firmware? In other words, are you seeing this issue after upgrading the driver/firmware from an older version to 13.10.271.283?

Best Regards

Hi,

Previously we used CYW43455 chipset with which we are not seeing the issue, we recently moved to CYW43012 chipset with which we are seeing this issue. 

 

We are using 4.9 kernel and the corresponding driver for that version.

 

Regards,

Rupesh

Hi @rupesh_theatro ,
Usually, these -110 errors can be ignored since they could be caused by delays in the SDIO bus. Can you share the SDIO mode configuration? You can cat /sys/kernel/debug/mmc<0 or 1>/ios to get it.
Also did "BRCMF_SDIO_MAX_ACCESS_ERRORS" limit help?

Thanks
