Framework_tool segmentation fault kubuntu 24.04.2 LTS

Framework Laptop 13 Linux
1

A brand new (received and installed the os today) framework 13 laptop running kubuntu 24.04.2 lts.

I can install and build a partially working framework_tool

sudo ./target/debug/framework_tool --info
[sudo] password for ul: 
Summary
  Is Framework: true

but I’m getting seg faults for most options. For example:

sudo ./target/debug/framework_tool --charge-limit
Segmentation fault

(charge limit is currently set to 60% via bios)

Is this a good question for the forums (if so where?) or should I post on framework-system github issues?

EDIT I managed to get the following back trace:

sudo rust-gdb --args ./target/debug/framework_tool --charge-limit

...

Reported and resolved (at least for me) here.

kubuntu 24.04.2 lts use v6.11 kernels. The framework_tool needs >=v6.12 kernels or an appropriately patched cros_ec_lpc 6.11 lkm to function.

Apparently, 24.04 lts is scheduled to get kernel 6.14 in August with the 24.04.2 → 24.04.3 update so best wait for that or go through the pain of compiling a patched cros_ec_lpc, DKMS compliant, 6.11 loadable kernel module (and then undoing that when the kernel updates to 6.14).
