No need for linux. If you don't mind installing firmware from random files on drive.google.com, you can grab the tarball referenced from the url above, unpack it, and copy brcmfmac43430-sdio.^(bin txt) into /sys/lib/firmware on your pi3 or pi0w. You will need to pad the .bin file to a multiple of 2048 bytes (eg by appending from /dev/zero) otherwise the verify after loading seems to fail. If you use the piwifi kernel (rootfs from wifi) as opposed to the pi3 kernel (rootfs from ethernet or sdcard with access to wifi), you'll want to rebuild the kernel in order to get the updated files into the /boot builtin fs. There should be a more definitive source for the firmware files somewhere. > Though there seems to be another unrelated problem that seems > not quite fixed. The other two fixes mentioned in that issue (turning off power management and harcoding packet priority to zero) were already in the plan 9 driver.
