Hi,
I am trying to enable Wifi on imx7d-pico using mainline
kernel.
imx7d-pico
has an AP6335 chip.
I am facing some issues related to the nvram file. I am
using
the
firmware
provided by Buildroot (brcmfmac4339-sdio.bin). I get the
following error:
[ 8.630380] brcmfmac: brcmf_sdio_htclk: HT Avail
timeout
(1000000):
clkctl 0x50
I have tried to use the firmware and nvram provided by
TechNexion
but I
get
the same error.
Is there anyone that could enable Wifi on AP6335 using
kernel
mainline?
What nvram file was used?
I am able to use Wifi on the board if I use the firmware,
nvram
file and
kernel
provided by TechNexion. They use a 4.1 kernel from NXP
with
the
bcmdhd
driver.
So I know that the hardware is functional.
Any suggestions as how to get it working with a 4.13 and
brcmfmac
driver
is
appreciated.
So the nvram file is specific to the wifi chipset on your
platform
so best
to stick with the provided one. The "HT Avail timeout" most
often
is an
indication that the firmware crashed. So getting more debug
output
would
help us understand how it ended up like that. Can you build
the
brcmfmac
with CONFIG_BRCMDBG and load the driver using:
$ insmod brcmfmac.ko debug=0x1416
Thanks for the reply!
Here is the log (using 4.14-rc1):

Any suggestions on this?
Sorry for not getting back to your earlier email. Thanks for the
reminder. So you tried different firmwares, right? Can you
provide
output of the following command:
$ strings firmware.bin | tail -1
for the firmwares you tried.
Regards,
Arend
Thanks for the reply!
Here's the output:

In both cases, I am using the nvram provided by Technexion.
That should be fine.
Can you try the patch below. It would give me more info on state of
firmware.

Arend
