Subject: WL12xx support for WL1270 and ti-connectivity firmware

Hi friends,

I searched through the mailing list archives to see if there's any
conclusive answer about this but didn't find any. I'm planning on
using the wl12xx driver in 3.0.35 for i.mx6 board with a murata
LBWA19XSLZ chip (TI WL1270 transceiver) and am checking if this might
work.

a) does wl12xx support wl1270?
I'm not certain whether or not the wl12xx driver supports wl1270. The
code does not mention wl1270. The defines/ops are prefixed with
wl1271. Eg:
linux-3.0.35$ egrep ieee80211_ops drivers/net/wireless/wl12xx/*.c
drivers/net/wireless/wl12xx/main.c:static const struct ieee80211_ops
wl1271_ops = {

Can I conclude that I should not expect this to work for wl1270? Or is
it just that wl1271 and wl1270 share compatible ops?

b) is there specific firmware I will need for the wl1270?
I see that wl1271 gets its firmware from ti-connectivity which has:
https://github.com/shaharlevi/linux-firmware-ti-connectivity/tree/ti-connectivity/ti-connectivity
wl1271-fw.binlinux-firmware: wl12xx-update STA FW supports 11n BA sessions
wl127x-fw-3.binlinux-firmware: wl12xx: Updated STA & AP FW for wl12xx-fw-3

I'm wondering if that wl127x includes wl1270 support.

Thanks for any advice/suggestions.

Thanks,
jayakumar

I have never heard of wl1270 while working at TI. My only guess is that
this is a chip based on wl1271 (since the Murata specs only say b/g/n
and no "a" which is the 5GHz support in wl1273). Maybe it's a cheaper
chip without Bluetooth? To be sure, you should ask TI.

Same as above... If this wl1270 is indeed based on the wl1271, it should
probably work. With the driver you may need to add some new SDIO IDs
for it to be recognized though.

I meant "in those logs", obviously. My phone's auto-correction is not
that good when writing technical terms. :)

Do you mean out-of-tree drivers? If they were in the mainline you should be able to upgrade.

Anyway, you should at least try to use compat (now called backport) to get the latest wireless stuff.

Usually this happens because you're not getting any interrupts. Are you sure the WLAN IRQ GPIO is correctly configured?

You should really be using the iw tool instead of the old wireless-tools. This probably won't make a difference in your case, but there's no reason to use a tool that had been deprecated for years...

There's nothing very useful in those kids
It just shows that the scan command was issued but you never got the scan complete interrupt.

Interesting. Try to take more logs, use 6625 for instance. This will
produce a lot of messages.

Another common cause for failed scan (and RX in general) is a wrong
clock frequency for the WiLink chip. Make sure you're using the correct
values in your board file.

Hi,

I'm now bringing up the board with the wl1270. I'm using 3.0.35 (stuck
on this kernel version due to other drivers). The good news is that
the chip is detected and wl12xx/wl12xx_sdio loads. However, I haven't
been able to get it to get any scan results and can't associate with
any AP (even open).

I'm using ti-linux-firmware-wl12xx-r3-m1-rc2.tar.gz for the nvs and fw files.

I retried with debug_level=256 (scan debug) and I see a lot of output
appended below. I haven't figured out how to interpret them yet. I'd
be grateful for any advice/suggestions on this.

Hi Luca,

I'll try to see how to switch to latest compat.

Thanks,
