MB2 Posted October 15, 2017 Share Posted October 15, 2017 Hello, i will move my project from RPI2 to tinkerboard. I have 2 Serial Converter, USB to RS422 and USB to RS485, both working on the PI. On the Tinkerboard with "ARMBIAN 5.33 stable Ubuntu 16.04.3 LTS 4.13.3-rockchip" runs only the RS422, the RS485 (Vendor 1a86) is not available as /dev/ttyUSB. What can i do?

MB2 Posted October 15, 2017 Author Share Posted October 15, 2017 Hi Igor, thanks for the reply, but I do not quite understand. I am not a specialist in the ux world, but only compile the kernel is not enough? As I see it is missing the driver for the CH340 / CH341 or even only the assignment of the Vendor / Device ID to this driver. I do not know how I can check whether the driver is available or how I can include. There is a driver for the converter, but only for kernels 2.x and 3.x http://www.wch.cn/download/CH341SER_LINUX_ZIP.html regards Marco Link to comment Share on other sites More sharing options...
martinayotte Posted October 15, 2017 Share Posted October 15, 2017 This is a bit strange that CH34x driver is missing, it has been added months, maybe year ago. Here is the results of "grep CH34" in Armbian defconfig : config/kernel/linux-sun4i-default.config:CONFIG_USB_SERIAL_CH341=m config/kernel/linux-sun7i-default.config:CONFIG_USB_SERIAL_CH341=m config/kernel/linux-sun8i-default.config:CONFIG_USB_SERIAL_CH341=m config/kernel/linux-sun8i-dev.config:CONFIG_USB_SERIAL_CH341=m config/kernel/linux-sunxi64-dev.config:CONFIG_USB_SERIAL_CH341=m config/kernel/linux-sunxi64-next.config:CONFIG_USB_SERIAL_CH341=m config/kernel/linux-sunxi-dev.config:CONFIG_USB_SERIAL_CH341=m config/kernel/linux-sunxi-next.config:CONFIG_USB_SERIAL_CH341=m Verify that is really missing by doing : find /lib/modules/ -name "ch34*ko" Check also "dmesg" while plugging the USB-RS485 device, you should see something like : [2830916.592706] usb 1-1: new full-speed USB device number 3 using dwc2 [2830916.776738] usb 1-1: New USB device found, idVendor=1a86, idProduct=7523 [2830916.776768] usb 1-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0 [2830916.776788] usb 1-1: Product: USB2.0-Serial [2830918.390022] usbcore: registered new interface driver usbserial [2830918.390154] usbcore: registered new interface driver usbserial_generic [2830918.390266] usbserial: USB Serial support registered for generic [2830918.393881] usbcore: registered new interface driver ch341 [2830918.394055] usbserial: USB Serial support registered for ch341-uart [2830918.394199] ch341 1-1:1.0: ch341-uart converter detected [2830918.397152] usb 1-1: ch341-uart converter now attached to ttyUSB0 Link to comment Share on other sites More sharing options...

EDIT : Another reason for by "bad", I'm still using Ayufan build ... So, it is a good oppotunity to add those drivers and test new Armbian ... I will probably commit that this afternoon.

MB2 Posted October 15, 2017 Author Share Posted October 15, 2017 no ch3xx.ko with "find /lib/modules/ -name "ch34*ko"" Link to comment Share on other sites More sharing options...
martinayotte Posted October 15, 2017 Share Posted October 15, 2017 In the mean time that I'm doing the required commit, you can use temporarily an Ayufan image, it has this driver. Link to comment Share on other sites More sharing options...
zador.blood.stained Posted October 15, 2017 Share Posted October 15, 2017 @martinayotte Tinkerboard images are not compatible with Rock64 ones, so there are no Ayufan's images for it Link to comment Share on other sites More sharing options...
martinayotte Posted October 15, 2017 Share Posted October 15, 2017 ... But, I will do the task for Rock64 ... Link to comment Share on other sites More sharing options...
TonyMac32 Posted October 15, 2017 Share Posted October 15, 2017 Thanks @martinayotte, I'm operating from cell phone right now, a storm took out my power... I'll check these when it comes back if it hasn't been done, it will need added to the Meson64 as well, I would expect. Link to comment Share on other sites More sharing options...
martinayotte Posted October 15, 2017 Share Posted October 15, 2017 Oh, to my surprise since I was still using Ayufan image on my Rock64, it seems that current Dev build, although building properly, isn't booting and get stuck at "starting kernel" ... Anyone got the Dev working ? Then, I've built Default version, and this one is working ... It is maybe question of DT itself or U-Boot, I will need to investigate more.

MB2 Posted October 20, 2017 Author Share Posted October 20, 2017 any news from the driver? So my project ist migrated to the tinkerboard with an ttl to rs485 adapter, but I would be happy if the usb adapter would work Link to comment Share on other sites More sharing options...
martinayotte Posted October 20, 2017 Share Posted October 20, 2017 The commit has been done 4 days ago : https://github.com/armbian/build/commit/d70ce66742a55579c49e712ce6a867c7ac68df83 So, if you build your own image, you will getting those USB-TTL dongles working.
