LiFePO4wered/Pi+

Dear people.

Since some time I user of LMS and Picoreplayers troughout the house for sonos like experience but better.
I recently wanted to use a headphone amp hat on a project and the only one was the Pirate Audio with screen and buttons.

A bit of an overkill but made me think of a totally different option. A portable wifi pocket streamer. Thanks to this amazing tutorial I was able to make it work https://forums.slimdevices.com/showt...l=1#post971970

But now the battery part. I for some time really liked the LiFePO4 idea since its more fire safe and durable.

It came in today, but in the newer version it needs a boot veryfication to stay powered for more then 5 minutes. So it really needs this driver
"The reason is that the LiFePO4wered/Pi+™ firmware includes a timeout for the
boot sequence with a default length of 5 minutes. If the LiFePO4wered/Pi+™ is turned on and doesn’t
get notified by the host daemon that the system has booted within 5 minutes, the power will be turned
off. "

I found out the hard way and installing the driver is not so simple for a tiny linux install unfortunately...
So installing it this way is not possible.

I hope someone here has experience getting it to work with a piCoreplayer setup?
Google only tagged people who had this in their signature but no discussions I could find so fat concerning picore player or other tinylinux distro's.

Thanks in advance!

p.s. Im a Linux newbie, but I try hard to get there to make it work always
