Subject: ath6kl: AR6004 failed to start on computer boot

Hi,

I have some problem with the AR6004 (hw 1.3) initialisation.
I'm using the compat wireless 3.6.6-1 package, with the ath6kl driver from
https://github.com/kvalo/ath6kl.git. (master branch)

The device seems not to respond after the firmware upload.
"ath6kl: htc_wait_recv_ctrl_message: Timeout!"
Increasing the timeout doesn't help.
Here is the log at startup.
http://pastebin.com/DsivqdDP

If I unplug and re-plug the adapter, every thing is going well.
http://pastebin.com/BTz0w5QL.

Any Idea on how to fix or workaround this issue ?

(I've also tried the recovery options recovery_enable=1 heart_beat_poll=200)

Regards,
Julien

Just to be clear I think a problem with USB code/hardware, most likely
SDIO doesn't have this issue.

Finally I got working USB boards again and I see the same thing:

Dec 13 01:43:21 x201 kernel: [ 24.843691] ath6kl: Failed to start hardware: -5
Dec 13 01:43:21 x201 kernel: [ 24.843781] ath6kl: Failed to init ath6kl core: -5
Dec 13 01:43:21 x201 kernel: [ 24.843849] ath6kl_usb: probe of 2-1.2:1.0 failed with error -5

> Any Idea on how to fix or workaround this issue ?

I remember seeing a test patch which did some low level reset on the
hardware. I need to dig that up and see if it helps.

Also adding delay to various places would be good to test, in case
hardware needs some time to initialise itself.

> (I've also tried the recovery options recovery_enable=1 heart_beat_poll=200)

I doubt this helps as we are not even able to upload the firmware.

I still have the problem on a reboot, but the device initialize itself
properly after a normal boot.

It's still a problem for me, I obtain exactly the same log.
ath6kl: Failed to start hardware: -5
Dec 13 01:43:21 x201 kernel: [ 24.843781] ath6kl: Failed to init

If you need to test anything don't hesitate to request me.

I haven't looked at all the details yet, but AFAIK this is about cold vs
warm booting the chip. When rebooting the host while maintaining the
power to ar6004 ("warm boot") ath6kl probe fails as the chip is in odd
state and needs to be reset. It's not about dowloading the firmware
image from user space, it's about starting the firmware inside the chip.

And besides, didn't udev finally fix that (after some "feedback" from
Linus) so that we don't need to change all the drivers?

Hi,

I'm having the exact same problem than Julien, (my kernel log are _exactly_ the
same than his).

A difference on the behavior: the problem is not on reboot, it's always present
(normal boot and reboot...).

But the "quick fix" witch consist in adding "reset_device" doesn't work, it just
goes into a loop (hardware_init fail->reset device->hardware_init fail->...)

Main difference is the linux system:
the architecture is ARM9 (armv4) with a buildroot system and kernel 3.6.7
note: hardware USB port is usb_v1.1 only.

I've tried ath6kl drivers from the kernel and the one from compat-
driver_next(2013-02-20)
=>same result.

The wireless USB dongle is working properly on my linux computer with the same
compat-driver and same firmware files, so it shouldn't have hardware problem

Another wireless dongle based on RALINK chipset is working properly on my ARM
system, so this shouldn't be an hardware problem from the board.

Any clue?

KR,
Yvan.

I am certain that the real problem here is that ath6kl is requesting firmware
with a synchronous call using request_firmware() rather than with the
asynchronous request_firmware_nowait(). That used to work, but updates to udev
caused the firmware read operation to time out. It works after a reset because
the file reading routines are now running; however, the correct fix is to
rewrite the firmware reading section.

Does 'modprobe -rv ath6kl' followed by 'modprobe -r ath6kl' make it work? If so,
then my idea about firmware loading might be correct. If not, then the problem
is somewhere else.

As modprobe uses insmod/rmmod for its heavy lifting, you are doing essentially
the same thing. It seems that the chip has some other problem. As I know nothing
about it, I cannot help.

that was the suggestion gave by Wei. The failure it seems
check hostapp area to check target status and reset the device
if needed.

Great that you figured it out yourself!
