"brcmfmac: brcmf_sdio_htclk: HT Avail timeout" on Thinkpad Tablet 10

[Sébastien Bourdeauducq]

[-- Attachment #1: Type: text/plain, Size: 662 bytes --]

Hi,

The Lenovo Thinkpad Tablet 10 is a complete disaster under Linux, and
among many problems the SDIO brcmfmac wifi does not work.

I get the following messages in the kernel log:
brcmfmac: brcmf_sdio_drivestrengthinit: No SDIO Drive strength init done
for chip 4324 rev 6 pmurev 17
brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50
[repeated]

and the network interface is never created.

I'm running kernel 3.18.4, my brcmfmac43241b4-sdio.bin is identical to
the one in the linux-firmware repository, and I have attached the
brcmfmac43241b4-sdio.txt that I have extracted from the EFI variables.

Any help would be appreciated.

Sébastien

This usually means the firmware did not start properly.

At first glance that looks fine to me. However, it is already late here 
so I will have a closer look tomorrow. If you can send a log with 
brcmfmac loaded with parameter 'debug=0x1416' that may give me some more 
clues.

When you say your firmware is identical what does that mean. Did you do 
a diff? Can you do 'hexdump -C brcmfmac43241b4-sdio.bin | tail -30'? I 
will be getting a laptop with 43241 integrated soonish (monday?). 
Hopefully it has same chip revision.

Arend

It is exactly this file (diff reports same content):

Hi Arend,
I am still experiencing the issue Sebastien initially described (no wlan0 device,
"SDIO drive strength" warnings etc) on a Thinkpad Tablet 10 for the latest
kernel release, 4.2. Doesn't the 4.2 kernel include the required fix?

Thanks,
Oleg
