It's a manufacturer software of standard serial to usb chip marked CH340
which helps to fix the problem below:
error: implicit declaration of function ‘signal_pending’; did you mean ‘timer_pending’? [-Werror=implicit-function-declaration]
and changed line:
which helps to fix next problem below:
error: unknown type name ‘wait_queue_t’; did you mean ‘wait_event’?
Additionally first pull request helped to merge changes for version 1.5 released in 2018-03-18: [https://github.com/juliagoda/CH341SER/pull/1](https://github.com/juliagoda/CH341SER/pull/1)
- Arch Linux 4.11.3-1-hardened
- Arch Linux 4.11.3-1-ARCH

Tutorial on Arch Linux
Tested for Arduino UNO R3 Clone
install required packages:
sudo pacman -S arduino arduino-docs avr-binutils avr-gcc avr-libc avrdude
if your system detects the package below:
pacman -Qs arduino-avr-core
you should remove it:
sudo pacman -R arduino-avr-core
we add current user to uucp and lock groups:
gpasswd -a $USER uucp gpasswd -a $USER lock
it's possible, that you have to load that module:
clone fixed driver:
git clone https://github.com/juliagoda/CH341SER.git
according to the original readme.txt, we use the commands below:
make sudo make load
to be sure, that module will be loaded after reboot, you can change file extension from ".ko" to ".ko.gz" and add it to drivers path:
find . -name *.ko | xargs gzip sudo cp ch34x.ko.gz /usr/lib/modules/$(uname -r)/kernel/drivers/usb/serial
if the command:
lsmod | grep ch341
shows some result, then:
sudo rmmod ch341 sudo mv /usr/lib/modules/$(uname -r)/kernel/drivers/usb/serial/ch341.ko.gz /lib/modules/$(uname -r)/kernel/drivers/usb/serial/ch341.ko.gz~ sudo depmod -a
let's connect Arduino UNO R3 Clone to USB input and check our results:
dmesg | grep ch34x
that's example of my command's output:
[ 492.836159] ch34x 3-1:1.0: ch34x converter detected [ 492.846265] usb 3-1: ch34x converter now attached to ttyUSB0
so our driver ch34x was successfully loaded and our port's name is ttyUSB0
Let's start our installed Arduino IDE.
First we should install package for Arduino AVR Boards from Boards Manager:
And now we must choose our port's name. My port's name is ttyUSB0.
Why we wanted arduino-avr-core package from official repo to be removed? Let's check it out.
sudo pacman -S arduino-avr-core
and let's reopen our Arduino IDE and check out boards list.
New label "Arch Linux Arduino AVR Boards" with boards has been added to boards list. It has the same options, so let's choose "Arduino/Genuino Uno" from a new part and upload our code to Arduino UNO R3 Clone.
It didn't work. I think, that the package was created for original arduino boards, which are not compatible with their clones. If you want to have installed the package and work on clone of Arduino, better choose the same option from part labeled "Arduino AVR Boards".
This driver is not compatible with the Olimex ESP32-POE rev C board
