RPi5 wifi no longer works

[Juanito]

I just updated firmware-rpi-wifi and regdb with the result that piCore64-16.x wifi stopped working:

Code: [Select]

Something to do with moving from /lib/firmware to /usr/local/lib/firmware and/or too many symlinks?

[Paul_123]

I’ll take a look. 

[Paul_123]

I just wrote a new card with piCore64-16, resized, installed firmware-rpi-wifi.tcz and wifi,tcz on a pi5.

wifi works just fine.

Are you sure you upgraded your rootfs to the 16.0.0 release.   The release candidate rootfs did not have the symlink from /lib/firmware to /usr/local/lib/firmware.

[Juanito]

The symlink is not there so I guess I must be using a pre-release version of rootfs-piCore64-16.0.gz (dated May 18)?

[Juanito]

Confirmed - I overwrote rootfs-piCore64-16.0.gz (and everything else) and the symlink is there now.
