You can enable the serial port by adding this line: enable_uart=1 in the file /boot/efi/config.txt and rebooting the Pi. If that doesn't work for you, you might consider temporarily loading a copy of Raspbian on an SD card just to do the fan setup, since that is what the hardware manufacturer expects you to be using. After configuring the fan, then put your Fedora SD card back in. The manual you linked to says that the settings are stored in EEPROM, so they should be remembered when you switch back to Fedora.

Yes, Raspian, although not mentioned explicitly in the manual.

Can you actually link to the hardware and the instructions you're attempting to follow/convert, it saves people actually trying to guess/interpret what that may be. > Thanks, Thomas > > In order to use bootloader, user need to have activated and free Serial Port on Raspberry Pi®.

I take it they're the details for Raspbian? _______________________________________________ arm mailing list -- arm@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to arm-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/arm@xxxxxxxxxxxxxxxxxxxxxxx
