AP firmware for TI wl1251 wifi chip (wl1251-fw-ap.bin)

AP firmware for TI wl1251 wifi chip (wl1251-fw-ap.bin)

Hi!

In linux-firmware repository [1] is missing AP firmware for TI wl1251 
chip. There is only STA firmware wl1251-fw.bin which supports managed 
and ad-hoc modes.

For other TI wilink chips there are <CHIP>-ap.bin firmware files 
(wl1271-fw-ap.bin and wl128x-fw-ap.bin) which support AP mode. But for 
wl1251 firmware file with guessed name "wl1251-fw-ap.bin" is missing.

Do you have any idea what happened with AP firmware for ti wilink4 
wl1251 wifi chip? Or where can be found? Guys from TI, can you help?

I see that STA firmware was added into linux-firmware tree in year 2013 
by this pull request [2].

It's a long time ago but IIRC wl1251 has not ever supported AP mode and
wl1271 was the first one to support it. But I might be wrong of course.

Support for AP mode in current kernel driver wl1251.ko is missing, but I
could try to write it if there will be firmware for it.

According to some TI whitepaper about TI wilink4 devices (wl1251 and
wl1253) those devices have support for some Soft-AP mode.

Hi! Anybody has some idea about that AP firmware?

Hi,
wl1251 does not support AP mode, so there is no firmware for it in the tree.

Hi Yaniv! I read on some TI whitepaper, that wl1251 hardware supports 
some Soft-AP mode. So I expect that either special FW is needed for it 
or somehow it is possible to use current released. Do you have any 
information about it?

Hi Pali,
This must be some typo, the device does not support Soft-AP.
More than that, wl1251 family is not officially supported via the mainline Linux.
For Soft-AP, and other new features based on Linux you should use WiLink8 chip family.

Yaniv

I guess you mean not officially supported by TI? Because wl1251 driver
has been in mainline for ages and reportedly working.

Too late for that, we already have the devices, and they were manufactured quite long
time ago.

Is it "hardware can't do AP", "firmware can't do AP" or "current drivers 
do not support AP"?

We know that current linux TI wl1251.ko driver does not support AP. And
I'm still do not know if "hardware can do AP" or not. Also I'm not sure...
maybe current firmware can be "forced" for implementing AP mode.

David Gnedt implemented packet injection for wl1251.ko via JOIN firmware
command. And he wrote me that aircrack utils contains one application
which implementing full AP station in userspace just via packet
injection radiotap (which is supported by wl1251).

So maybe using other firmware (filter) commands together with current
packet injection implementation could be possible to create AP mode
(usable for standard hostapd daemon)? Just thinking...

Anyway, other TI wilink devices have different firmware for AP mode...

As both Firmware and HW are not in a stage where they can be modified, there is no support for AP mode in both.
