Hmm so is this firmware file also something that should really be generated separately for each board? Or can the same one be used for all BBB black wireless and green boards?

See the LKML thread "[PATCH 0/6] wl1251: Fix MAC address for Nokia N900", at least with wl1251 the calibration has been done for each n900 device during production.

From what i can tell from TI, it should be good for all wl1835 modules

that use two wifi antenna's.

(that's the magic in: WL1835MOD_INI_C2PC.ini)

We are using the same wl18xx-conf.bin firmware for:

Original CircuitCo (now out of production) wl1835mod cape for BeagleBone Black updated GateWay Cape from embest (this was meant to replace the wl1835mod cape)

SeeedStudio BeagleBone Green Wireless
BeagleBone Black Wireless

and the upcoming: (jason just sent me the next alpha, so i'll have a patch after i verify all changes..)
BeagleBone Blue

For FCC testing, this was the same firmware (wl18xx-conf.bin) that SeeedStudio used when they did the official FCC testing on the Green Wireless. I believe GHI Electronics did the same with the BeagleBone Black Wireless, but i wasn't CC'ed in that email conversation, so i can't say with 100% certainty..

I believe the correct statement is BWxx, but BWBx reserves the option to be software incompatible in some way. My preference is to have it boot anyway, but I believe that is only dependent in the bootloader.

PATCH 2/4 ARM: dts: Add am335x-boneblack-wireless

Quoted 11 lines · Jason Kridner
Quoted 9 lines · Robert Nelson

BeagleBone Black Wireless is clone of the BeagleBone Black (BBB) with the Ethernet replaced by a TI wl1835 wireless module.

This board can be indentified by the BWAx value after A335BNLT (BBB) in the at24 eeprom:
BWAx [aa 55 33 ee 41 33 33 35 42 4e 4c 54 42 57 41 35 |.U3.A335BNLTBWA5|]

I believe the correct statement is BWxx, but BWBx reserves the option to be software incompatible in some way. My preference is to have it boot anyway, but I believe that is only dependent in the bootloader.

So does this patch need updating for that?

Regards,

Tony

No, it is bootloader controlled.

What about the patch description? Does it need updating or is that an Acked-by?

Sorry for the phone mailer (HTML).

OK fixed that to Acked-by :) Applied into omap-for-v4.11/dt and pushed out.

BBB Green Wireless seems to work nicely for WLAN out of the box with these patches :)
