Add support for ODroid / Raspberry Pi OS 64-bit

I believe the Micro USB port on the Odroid C2 is OTG... so do you think it would work?

It's possible. I don't have one on hand to check, but I'd welcome reports from anyone who does.

Summary

The big blocker is support for the usb-gadget-hid in the kernel, which Raspberry Pi OS has natively, but it's hard to enable on other boards.

Board	OS	Status
Raspberry Pi 4B	Ubuntu 20.04 LTS 32-bit	Works with the standard installer
LibreComputer Tritium H5	Armbian_21.02.1_Tritium-h5_buster_current_5.10.12	TinyPilot on LibreComputer Tritium
up squared	Ubuntu 18.04	confirmed working, required manual work to adapt the install script for Ubuntu
ODroid C1+/C2/C4	ubuntu-18.04.3-3.16-minimal-odroid	Probably won't work because the latest official ODroid builds are on v3.16 of the Linux Filesystem, and TinyPilot depends on configfs-usb-gadget-hid, which was added in 3.19.
ODroid C1+/C2/C4	ubuntu-20.04-3.16-minimal-odroid	Same as above.
ODroid C1+/C2/C4	DietPi 6.31.2	Still on the 3.16.85 kernel, so similar reason to above.
ODroid C1+/C2/C4	Armbian_20.05.2_Odroidc2_buster_current_5.6.15	This seems close to working, but it fails to create the `/dev/hidg0` file
ODroid C2	ArchLinuxARM	This article claims to demonstrate it, but I tried those exact steps, and it failed. It's worth noting that they used a different kernel version than currently ships with ArchLinuxARM.
Banana Pi M2+	2020-04-23-raspbian-stretch-bpi-m2p-sd-emmc	Uses Python 3.5, but TinyPilot requires 3.7+. I even tried recompiling 3.7 from source, but it fails on `python3 -m venv venv`

It's possible. I don't have one on hand to check, but I'd welcome reports from anyone who does.

I had a good go at it today.. Got debian stretch on an sd card and all updated. I had to make a couple of changes to the quick_install script.. Mainly either side of the ansible install.. Something like +u and -U above and below so that it would install..

But after that, it failed while building wheels.. something like "bdist wheel" as an invalid command...

I;ve not got it powered up at the moment so can't get exact errors.

The bdist_wheel is an innocuous error as far as I can tell. It's a bug in Ansible's pip installation, but it seems to continue the install using another method. If it failed, there should be an error further down in the Ansible log.

Ah, then maybe i shouldn't of quit the install :) I'll try it again tomorrow and get back to you.. hopefully i've ordered the correct hdmi to usb adapter..

I got this one because the one linked from your blog had a months wait time!

That's a slightly different one, but all these products are just different packaging on top of the same MacroSilicon MS2109 chip, so it should work exactly the same.

So i went back to a fresh debian install and ran through it again..

i had to change a small part of the script :

set +u
. venv/bin/activate
set -u

And this is how it finished :

@KuroSaru

Oh, I forgot that ODroid is 64-bit. I haven't tested with aarch64 yet.

@KuroSaru got TinyPilot working on an aarch64 beta of Raspberry Pi OS. They had to manually run sudo apt-get install libffi-dev but that doesn't look like it's your issue.

Would you be able to link to a gist of your full log? I can't tell from the snippet where the failure happened in the process.

I would, but i seem to of corrupted the SD card again.. The power supply i'm using is a bit loose and it seems to have moved and shafted it.. if i get it going again i'll let you know... I may just buy a pi4 though to be honest.

OK, so it's back up.. Here's the gist :

Thanks! It looks like it's failing while trying to install ansible. I just merged in #88 to let Ansible build with wheel like it's trying to do. It installs fine either way on Raspberry Pi OS 32-bit, but it might make a difference on aarch64.

Can you try running the quick install command again now that I've updated it?

curl -sSL https://raw.githubusercontent.com/mtlynch/tinypilot/master/quick-install | bash -

Edit: Actually, to avoid potentially pulling a cached version of the install script, it's better if you run the specific branch's script:

curl -sSL https://raw.githubusercontent.com/mtlynch/tinypilot/install-wheel/quick-install | bash -

I've just done

sudo apt-get install python3-dev

And it seems to be potentially working.. bear with me.

Edit : I'm still using the old quick_install that i modifed...

Edit again: I think the only error i got is

TASK [mtlynch.tinypilot : enable dwc2 driver in boot config]     ***************************************************************************************************************************************************
fatal: [localhost]: FAILED! => {"changed": false, "msg": "Destination /boot/config.txt does not exist !", "rc": 257}

hitting the IP i get an nginx welcome page though..

It looks like you're still pulling the old Ansible role. Can you give the new script a try?

curl -sSL https://raw.githubusercontent.com/mtlynch/tinypilot/install-wheel/quick-install | bash -

It's idempotent, so running it multiple times should be fine.

https://raw.githubusercontent.com/mtlynch/tinypilot/install-wheel/quick-install

Giving it a go now.. added my changes in so it runs for me.

So, it was all going great.. no bdist errors.. then this happened :

https://gist.github.com/mtlynch/4e58cb6a4b5826f75b07b2b04ef12745

im still just getting an nginx welcome page.

I've noticed there's no /opt/tinypilot folder.. which tinypilot.conf seems to be pointing to..

Just a ustreamer folder.

[maintainer edit: moved long output to separate gist]

I'm using Ubuntu 18.04 (x86_64) bits it seems that the dwc driver loaded is dwc3 though, I'm not sure it makes a difference. I tried to load dwc2 but it doesn't seem to do anything.

cat /sys/kernel/config/usb_gadget/g1/UDC 
dwc3.0.auto

Ok, i'm an idiot, it works perfectly fine, I was just running tiny pilot as my user and didn't have permission to /dev/hidg0 running tinypilot as root fixes the issue.

Thanks ! Sent you a beer.

@lamarios

Thanks for the donation, @lamarios!

Did you have to do anything special to get /dev/hidg0 to appear under Ubuntu 18.04 or did it just work right out of the box with the same TinyPilot scripts?

It worked straight away with what's in the repo.

I spent some time experimenting with other boards this week, but wasn't able to get TinyPilot working. I updated a comment near the top of the thread for reference.

For the up squared board. The install script probably works but I didn’t use it because I already had some conflicting services installed so I went the manual way.

I've had to do some tweaking due to poor detection of CPU type in the installation scripting (Ansible), but I've manged to get all variants of the LibreComputer Tritium H3 working with armbian.

@WarheadsSE

@WarheadsSE awesome! Could you share the configuration you used?

@mtlynch

@mtlynch That's the plan. I have to dig it all out of the nodes 😅

This gist covers the items needed to enable OTG, but I haven't yet found time to document a walk-through of how to enabled device tree overlay.

Said gist updated (plus another) for LibreComputer Tritium

@mtlynch

Board	OS	Status
LibreComputer Tritium H5	Armbian_21.02.1_Tritium-h5_buster_current_5.10.12	TinyPilot on LibreComputer Tritium

Here's a new entry for above @mtlynch 👍

@WarheadsSE

@WarheadsSE - added, thanks!
