Installing CH431SER on Ayufan 0.9.14: gitlab-ci-linux-build-159

[Thisone]

Hello

when I try to install the Driver CH341SER from CH341SER_LINUX.ZIP - 南京沁恒微电子股份有限公司 (wch.cn) for the Ayufan linux build. I get this error Message during the compilation:

Code:

rock64@rockpro64:~/CH341SER_LINUX/driver$ make

Makefile:5: recipe for target 'default' failed

I want to use the PineDisplay as Display on Linux and since Ayufan has a Documentation how to use it on his Linux Build, i use it.
But i need to install the Driver to use a CH340c RS485 to USB converter.

Any help is greatly appreciated.

What version of gcc you are using? Your gcc doesn't understand the two commandline options '-mgeneral-regs-only' and '-mcmodel=large'

I'm on 6.0.0-1164-ayufan and compiling with gcc 13.1.1 that driver works like a charm:

Code:

$ make
make -C /lib/modules/6.0.0-1164-ayufan-ga2fd0c498/build  M=/tmp/CH341SER_LINUX/driver  
make[1]: Entering directory '/usr/src/linux-headers-6.0.0-1164-ayufan-ga2fd0c498'

That driver loads into that kernel without complaint:
[ 152.041600] ch341: loading out-of-tree module taints kernel.
[ 152.042335] usbcore: registered new interface driver usb_ch341

[ 152.042344] ch341: V1.6 On 2022.08

May be is is incompatible with the legacy kernel?

I choose the Version, because it is marked as the latest stable build, but I'll try updating the Compiler if you think that would solve the Problem.

I still get the same error after updating gcc to gcc-9 following this tutorial: How to Install GCC Compiler on Ubuntu 18.04 | Linuxize

I don't know about "latest stable build." You are just using a lot of legacy software. Kernel 4.4 is legacy, gcc-9 is legacy. Try to use an older version of your driver that fits into that environment. For example https://github.com/juliagoda/CH341SER/tree/ubuntu

There is also a CH341-driver allready included into 4.4. The README.md of the vendor-driver states, that this driver is too old. I think the vendor has adapted the driver to modern gcc/kernel versions, because x86_64 is not holding back at 4.4. That often breaks compatibility to older versions.
