When purchasing the board, the bootloader firmware specified version 2023. With this version, it was possible to set the country code.

After updating the bootloader firmware to version 2024-12-07, setting the country code stopped working.

The bootloader firmware does not get involved with WiFi setup so closing as can't reproduce. This will be due to something else on the OS image so I recommend installing a fresh RPi OS image.

[rseleven]

@timg236, have you tried to reproduce the problem?

[lurch]

@rseleven If you're convinced that this is a bootloader firmware problem, you can try using rpi-eeprom-update -f to downgrade to an older firmware and see if that fixes the problem.

I agree with Tim that it's more likely to be an OS-side problem (either in the kernel or driver) rather than a firmware problem, so if you're still experiencing the problem after installing a fresh copy of Raspberry Pi OS, please open a new issue at https://github.com/raspberrypi/bookworm-feedback/issues with detailed reproduction steps, and I'll try to investigate the issue further.

Thanks for the detailed answer. I'm sorry, I was mistaken about the connection between bootloader/GPU firmware and regulatory country code.
