This hardcoded address seems to be the same as what is used by the rpi people: https://github.com/RPi-Distro/firmware-nonfree/blob/master/brcm80211/brcm/brcmfmac43430-sdio.txt

This No, the real MAC address I see is different from the one in the .txt file: wlan0 Link encap:Ethernet HWaddr 00:AE:FA:8D:95:E5 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

This > No, the real MAC address I see is different from the one in the .txt file: Ahh, good. I wonder why it is then listed (twice even) in the .txt file.

Noticed the file used by some of the Allwinner boards contains: https://build.opensuse.org/package/view_file/hardware/bcm43xx-firmware/brcmfmac43362-sdio-cubietruck.txt == # Board Revision is P307, same nvram file can be used for P304, P305, P306 and P307 as the tssi pa params used are same #Please force the automatic RX PER data to the respective board directory if not using P307 board, for e.g. for P305 boards force the data into the following directory /projects/BCM43362/a1_labdata/boardtests/results/sdg_rev0305 == So apparently some values involve low-level hardware tuning, and it's possible you need a different file if the PCB layout of the board you are using is changed at some point. This makes it kinda difficult to have a common rootfs for more than one board. Would be nice if they moved those values to device tree. Yours sincerely, Floris Bos
