** Description changed: + [ Impact ] + + Wifi performance for the Pi 500 is extremely variable. While it + initially will connect to an AP, when attempting to use the connection + for any length of time (e.g. playing a video for a few minutes), it will + drop and have difficulty reconnecting (though it will ultimately + manage). + + This is because the updated firmware for the wifi module is failing to + load as the links pointing the kernel to the correct files for the board + are missing. + + [ Test plan ] + + * Flash ubuntu noble image to an SD card + * Boot SD card in a Pi 500 or 500+ (both have the same wifi modules and the same internal ID used to negotiate which firmware to load) + * Check dmesg output includes "Direct firmware load for brcm/brcmfmac43455-sdio.raspberrypi,500.bin failed with error -2" + * Do not connect ethernet, but connect wifi to an AP + * Browse to youtube and watch a video for a few minutes; connection should drop at some point and the video will stop + * Enable proposed + * sudo apt install -t noble-proposed linux-firmware-raspi + * sudo reboot (firmware is only loaded on boot) + * Check dmesg output does *not* include "Direct firmware load for brcm/brcmfmac43455-sdio.raspberrypi,500.bin failed with error -2" + * Connect to wifi + * Browse to youtube and what a video for a few minutes; check connection is stable + + [ Where things could go wrong ] + + In this case, we're not defining any new wifi firmware, just adding + links to the package to load the correct firmware on this platform. As + such we don't need to worry about breaking any platforms other than the + 500 (all firmwares and links for other platforms are untouched). On the + 500 there is obviously the possibility of breaking wifi, but the test + plan proposed covers this. + + [ Original description ] + Firmware load for the wifi module on the pi 500 is missing because the symlinks for that model are not present under noble.
