Description

This was working on the RPi used with the 7" touchscreen. But now it's not working with the boards working with the TFT displays.

Need to investigate what broke.

History

#1 Updated by Hammel about 1 month ago

See this rpi forum post. Apparently I might need to fallback to older firmware.

wget https://archive.raspberrypi.org/debian/pool/main/f/firmware-nonfree/firmware-brcm80211_20161130-3+rpt3_all.deb
ar firmware*.deb
tar xf data.tar.gz
cp lib/firmware/brcm/* to RPi

The downloaded .deb is in rpi2/extras/netconfig.

According to this thread, specifically this post, the firmware was broken on 3b+ and 4's with an update pushed on Jan 25h. I"m using a Jan 8th download, so rebuilding the firmware might fix this problem. Maybe. However, this is from the RPi firmware-nonfree repo, which I"m not currently using. So I should add that to the dev platform build first.

Using platform-nonfree should allow me to change how I grab the brcm firmware and .txt files. Currently they are in fw.cfg, which might need more special case handing on where to grab them from.
