build ch341 module on 2g iot

eltsov_da

Hi everybody.
I try to build ch341 kernel module for Orange Pi 2g IOT
did the following steps:

git clone https://github.com/OrangePiLibra/OrangePi.git
cd ./OrangePi
./Build_OrangePi.sh
{input root password}
{kernel/uboot/rootfs}
{“OrangePi 2G-IOT}
{wait}
cd ./OrangePiRDA
{“OrangePi 2G-IOT}
{wait}
{enter root password}
{Build Module only}
{got path to build modules}

But I can't understand where I can select which module I build?
I can see ch341.c file in ~/OrangePiRDA/kernel/drivers/usb/serial
But no .ko file anywhere.

Best regards Denis Eltsov
