How to install CH34x driver on 2S

[hikaru 0]

I wanted to use an Arduino compatible machine and tried to make a driver for CH34x but couldn't.
(Tinker Board 2 Debian 10 V2.0.0)

I tried the method posted on this site.
https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers/linux

I put the linux header like this.

wget https://github.com/TinkerBoard2/kernel/releases/download/tinker_board_2-debian_10-2.0.0/linux-headers-4.4.194_4.4.194-1_arm64.deb
dpkg -i linux-headers-4.4.194_4.4.194-1_arm64.deb

Has anyone succeeded?
Or, if you have an installable ch34x.ko, I would appreciate it if you could share it.

sudo insmod ch34x.ko

As a side note, in the case of Tinker board S, Arduino compatible machines were recognized without installing any drivers.
(Tinker Board S Debian 10 V3.0.11)

Thank you.

Hi @hikaru

I use Tinker2S version 2.0.0-20210413
CONFIG_USB_SERIAL_CH341=y
Actually insert CH340 USBtoUART
linaro@linaro-alip:~$ ls -al /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 Dec ?8 04:04 /dev/ttyUSB0

If you have any questions, Please provide dmesg kernel log information.
Thanks

Thank you, Joe!

I didn't know how to set "CONFIG_USB_SERIAL_CH341 = y", so I sent a question via dmesg.🙏

Sorry, Joe.

I misunderstood dmesg as a direct message.
Rewrite in the thread.
I have little knowledge about linux and I don't know if I can ask the question correctly, but I investigated how to do it.

And I referred to the method on this page.
https://tinkerboarding.co.uk/forum/archive/index.php/thread-576.html

Yes, you need rebuild the kernel.

step 1. download kernel 
git clone https://github.com/TinkerBoard/debian_kernel.git

step 2. add the following line to arch/arm/configs/miniarm-rk3288_defconfig
CONFIG_USB_SERIAL_CH341=y

step 3. rebuild the kernel
make ARCH=arm miniarm-rk3288_defconfig
make zImage ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

then you will get a new zImage file under arch/arm/boot

step 4. replace the zImage file which is in your boot sdcard

When building the kernel Which file describes "CONFIG_USB_SERIAL_CH341 = y" on 2S version 2.0.0-20210413?

Or is there an easier way to get an OS with "CONFIG_USB_SERIAL_CH341 = y" set?

Thank you for your advice.

I tryed this method on 2S version 2.0.0-20210413.

make ARCH=arm64 tinker2_defconfig

Then I got ".config" file.
And It have line "CONFIG_USB_SERIAL_CH341=y".

Next step

make ARCH=arm64 rk3399-tinker_board_2.img -j24

I got these errors.

How Can I build kernel ?
