recent balenaOS versions do not support lirc-rpi

[curcuz]

lirc-rpi got deprecated since kernel 4.19 so deploying this project to recent balenaOS versions will result in a broken app. I need to update the configuration and the business logic to gpio-ir

Thanks for the note. I am waiting to experiment. Please let me know if you want me to do some changes and i can send you a PR as well.

[curcuz]

hey @nk-gears I will try to get to this on Friday, afaict it should not be a ton of work, stay tuned!

[nk-gears]

@curcuz Thank you Appreciated.

[nk-gears]

@curcuz any update on this?

[curcuz]

@nk-gears I have a WIP PR up ( #3 ) with the server part done, you can test it with any HTTP client from simple curl to fancy PostMan :) next week I will work on the frontend GUI - I'm pretty excited about this as now we can allow the user to basically design their own virtual remote :)

@curcuz I've been testing out your WIP PR. It looks great in theory. I get a valid response from the 'list saved commands' endpoint. But when I try and save a new command I get the following response:

Command failed: ir-ctl -r/data/swing -d /dev/lirc1 -1
/dev/lirc1: cannot open: No such file or directory

I've configured the dtoverlay as per the README and checked that my config.txt file on the boot partition does indeed have the following set:

dtoverlay=lirc-rpi
dtoverlay=gpio-ir,gpio_pin=23
dtoverlay=gpio-ir-tx,gpio_pin=24

What exactly creates /dev/lirc1 and do you have any pointers as to why its not there when running the ir-ctl command?

[curcuz]

hey @grahammcculloch /dev/lirc1 should be "created" by dtoverlay=gpio-ir,gpio_pin=23 - what devices do you see in /dev with namespace lirc ?

[grahammcculloch]

@curcuz here's my /dev:

No sign of any lirc devices!

[curcuz]

@grahammcculloch it looks like driver wasn't loaded - what OS (and version) are you running?

[curcuz]

also does dmesg | grep lirc produce any interesting output?

[grahammcculloch]

@curcuz thanks for your questions. In response:

$ cat /etc/os-release
ID="balena-os"
NAME="balenaOS"
VERSION="2.47.0+rev1"
VERSION_ID="2.47.0+rev1"
PRETTY_NAME="balenaOS 2.47.0+rev1"
MACHINE="raspberrypi4-64"
VARIANT="Development"
VARIANT_ID="dev"
META_BALENA_VERSION="2.47.0"
RESIN_BOARD_REV="a08e3d7"
META_RESIN_REV="8b48eee"
SLUG="raspberrypi4-64"

And dmesg | grep lirc returns nothing.
