NanoPi R2S - OTG g_serial(ttyGS0) not working


Recommended Posts

Posted
Armbianmonitor:

Object: Enable OTG serial console capability( It was enabled by default I think )

 

What I was checked/tested:

 g_serial on /etc/modules

 ttyGS0 on /etc/securetty

 serial-getty@ttyGS0.service enabled

 dwc3-0-host enabled/disabled

 Windows 10 1809 host g_serial recognized R2S as 0525:A4A7(rev0509)

 

Behavior:

   OrangePi-Zero:  Works well( g_serial recognized as same VID/PID but rev0419 ) <== There are no problems on Windows host driver or configurations[ELMO GMAS(5/4/2014, v2.0.0.1) / usbser.sys(v10.0.17763.1)]

   NanoPi-R2S: Connection fail. Even manual configure 9600 through 115200 bauds. => Putty alerts few minutes later 'unable to configure serial port'

We plan to refresh device tree in upcoming 5.10.y kernel (welcome to help out) ... currently we still sit on early implementation, taken from FriendlyElec legacy kernel. There is a refreshed DT in DEV kernel. You can try to build from sources or just use nightly builds, but you need to set: fdtfile=rockchip/rk3328-nanopi-r2s.dts in /boot/armbianEnv.txt

 

Try. If you manage to get it working, patch cleanup, moving away from our 1st implementation, adding what we added ... https://github.com/armbian/build/tree/master/patch/kernel/rockchip64-dev

Thanks for your very detailed informations.

I also suffered poor entropy too. It really sounds great.

I really wish to test dev branch kernel /w new device trees and hwrngd support.
But, actually I have no Armbian build environments as for now. :(
I will wait until nightly or stable releases.

Branch "desktop", which is going to be merged in 1-2 months, also supports native arm64 compilation. You can build things on your board. No excuses :) (but its currently in WIP state so it might break)

What we don't have are resources to deal with "everything". Plans to implement this or that can easily be extended over few releases. A year can slip by and there are slim chances that features just show in mainstream.  Sometimes they do, but usually much later.
