There are still some weird things happening with the modem sometimes. Like it dissapearing for no reason at all, or it only showing up minutes after booting. Mine seems to work pretty well though, i think it reached 200mbit easily when doing a speedtest (went through my 2gb prepaid test card in...

The problem is that alsa/pulseaudio sees the channel mapping as : Channel Map: front-left,front-center,front-right,rear-center Instead of the 4.0 setup it should have by default (which would be front-left,front-right,rear-left,rear-right) I tried forcing this in several places in the pulseaudio...

Yes, that's the connector. You can also try limiting the charge current to 2A max. (if you're using a > 2A charger) (ED also saw overheating with his 3A charger (the battery temp protection seem to be set VERY conservative)). systemctl stop pyra-thermal echo 2000000 > usb_max_current...

Try plugging the charger into the usb3 micro port (the one next to the blue port, you can plug a normal microusb plug into the larger side (probably upside down if it's anything like mine) ). That seems to behave a little better.

All that stuff is a bit behind, since i changed the way images are built. Currently working on getting everything back to the way i want it to function. (installing to emmc, and automatically resizing sd cards)

Two months.

It's far safer to just use a disk image writing tool instead of messing about with dd. raspberrypi points you to https://www.balena.io/etcher/ for example, which has a nice gui where you can just select the .img.zip and an sd card and it'll write it. Also works on mac and windows. You can skip...

I've created some new os images. https://packages.pyra-handheld.com/images/buster/ the img.zip need to be unpacked, then written to an sd card. If you've previously made an installer sd card, you can remove the rootfs.tgz from that, copy pyra-debian-buster-mate-rootfs.tgz to the card, and...

The annoying heartbeat led is there so i can easily see if the prototype has crashed. It still seems to have some stability issues when the battery stops charging. you can turn it off by editing /etc/default/leds, and changing "hearbeat " to "none" on logo:red:bottom, then running "sudo...

Yes, there are two chips, one that takes care of the charging, and one that turns the battery voltage in a percentage, the charging one should work fine.

the battery percentage in that kernel is wrong.

All the dbp stuff is completely untested, so don't expect too many things to work. Most/all of them are also built for the previous debian version, so it might be looking for older versions of libraries. They probably all need to be rebuild for debian buster.

It shouldn't touch anything other than the partition it booted from. When you get to the desktop it will probe for removable disks and mount them, (like when you insert an sd card in another slot, or attach a usb device), and it just mounts whatever is on the emmc as part of that, it doesn't...

f2fs is used instead of ext4 because it should behave better on flash based media. https://en.wikipedia.org/wiki/F2FS Use a disk image writing tool to dump the .img onto an sd card instead of dd , there are lots of them, rpi uses the same method to make their sd cards (...

Yeah, the only thing you should be looking at is what's on the serial output. You can't tell what's going on just from what's on the screen or how much power the charger takes. It does dump a lot of info on there, so sometimes you need to scroll up through quite a lot of stuff to find what's...

yes

The initramfs runs a script at boot that detects if there's a microsd card inserted, and switches to that if one is there. https://dev.pyra-handheld.com/packages/pyra-config/blob/master/initramfs/pyra-emmc-switch It will disable the emmc, so the installer sd card probably won't work if there's a...

/usr/share/pyra/bin/pyra_test_inputs but it's not really meant to run with Xorg and the pyra input daemon active. You can also run it by selecting a kernel with the (hwtest) option in the boot menu. That script stil needs a lot of work, so a lot of tests fail, or take a really long time. The...

It typing loads of "+" in the username prompt for the first-run-wizard seems to happen sometimes, I haven't found out where that comes from yet, it never does it when you're probing the input devices to see which one causes it :). You can just backspace/delete them and everything works fine...

reflashing it won't actually help with the two batteries thing, you need to install the other kernel package that has the battery fixes in it. apt update apt install linux-image-4.19.60-letux-lpae-pyra or apt install linux-image-4.19.60-letux-lpae-pyra-nobat ( modified kernel that can boot the...
