Title: PiCore busybox snapshot build
Post by: snecker on December 17, 2020, 06:03:10 PM

I'm currently attempting to run:

hwclock -s

on a Pi Zero however I get the error:

hwclock: settimeofday: Invalid argument

This is due to a breaking change earlier in the year.

The fix seems to have landed yesterday in busybox but I only have access to armv7 builders and I just get

Illegal Instruction

when I attempt to run this build on the PiCore, understandably.

If someone can point me in the right direction to get an armv6 version built that would be appreciated.

Hi snecker
Welcome to the forum.

I see in PiCore 12.x  util-linux.tcz  contains  /usr/local/sbin/hwclock:
http://tinycorelinux.net/12.x/armv6/tcz/util-linux.tcz.list
You don't mention which version of PiCore you are running, but it's also available in 11.x. 10.x, and 9.x too.

Sorry, its the latest 12.x release which includes BusyBox 1.31.1

Thank you for the advice about util-linux, I am just attempting to compile this now.

No need to compile. util-linux.tcz is a prebuilt extension you can install. If your Pi is connected to the network, then:

Code: [Select]

tce-load -wi util-linux

Ok, I realise now I was trying to do:

Code: [Select]

hwclock -s
as a regular user and the error was misleading.

So currently the busybox 1.31.1 version of hwclock is broken, util-linux version is not.

Thanks!

Since the  busybox hwclock  is in  /sbin, I would expect it needs to be run as root. Does this work:

Code: [Select]

sudo busybox hwclock -s

No, this doesn't work but util-linux from the repository does, thanks!
