Problem With Non Raspberry OS about txtempus

[hzeller]

If txtempus gives out that message, then it would fall back to Raspberry Pi 3, so that should probably just work in your case.

But you need to be root to be able to access the GPIO pins. Did you start txtempus with sudo ?

I su to root rather than have a user with sudo privileges, so I ran it as root.

[hzeller]

it couldn't memory map the GPIO area of the Raspberry Pi, that should not be dependent on the operating system (I used it at least with DietPi). This is why it looks like you're not running as root.

Anyway, if you're running a non-standard operating system on your Pi, you'll have to figure out the details involved getting it to run.

OK. Thanks. It was worth a shot.

I'm running Debian 10 on my Pi Zero W v1.1. Debian sets CONFIG_STRICT_DEVMEM=y which blocks mmapping on /dev/mem unless you pass iomem=relaxed on the kernel command line (by editing /boot/firmware/cmdline.txt). This may not apply in OP's specific situation but leads to a similar error, so I found myself here.
