Hello, next question.
In my task, my software controls external devices via the rs-485 interface.
I have a Moxa UPort-1450 in my work.
When I connect Moxa to M2, I see a USB adapter, but I don't see the interfaces I need to work.

There is an adapter and the interfaces I need here.
Experts from Alt Linux say that you need to build a kernel with the option:
CONFIG_USB_SERIAL_MXUPORT=m


And I may need a driver for moxa.

I'm asking you to help me get moxa to work at the station M2.

Thanks in advance

Hi

I found the driver for your device here
https://moxa.com/en/support/prod ... ntation?psid=114475

You must do step 3.3 in the readme and compile a new kernel with the driver for kernel 4.19.

Perhaps Firefly can help build a new image for you next week or later.

Copy the code

There are four RS-232 interfaces, and I can work with them, however, to switch to RS485 mode (according to the moxa documentation), use setserial, but setserial does not work, because the driver does not support ioctl. And how else to switch the port to rs-485, I do not know.

Example:
(i)The following command sets the interface of “/dev/ttyMXUSB0” to RS-422:
(ii)Use the following command to look up the serial settings of the current port:
# setserial /dev/ttyMXUSB0 port 0x2
# setserial -g /dev/ttyMXUSB0

1. 
   
2. root@firefly:/lib/firmware# setserial -g /dev/ttyUSB0
   
3. Cannot get serial info: Inappropriate ioctl for device
   
4. root@firefly:/lib/firmware#
   

Copy the code

I need RS-485 interfaces, but how to get them is not clear. I would be grateful for any help in solving this problem. Thank you for your attention and help.

I'm afraid the problem is with the driver CONFIG_USB_SERIAL_MXUPORT=m.
Maybe you still need to use the official driver, as lonewolf31 said.
You can find the corresponding linux-header here, linux-headers-4.19.xxx_arm64.deb.

Thank you very much, I will try to follow your recommendation, I will report the results.

Hi, do as follows to see if the driver is loaded normally.

1. tar -zxvf moxa-uport-1200-1400-1600-series-linux-kernel-4.x-driver-v4.1.tgz
   
2. sudo dpkg -i linux-headers-4.19.219_4.19.219-358_arm64.deb
   
3. sudo apt update
   
4. sudo apt install gcc
   
5. sudo ln -s /usr/bin/python3 /usr/bin/python
