Hi.
Could someone advise me, how to enable the serial port for Vu+ Zero 4K in Linux OS ?
I learned on the OpenATV forum that this Zero 4K has its serial port "locked" (non-functional for Linux system) after successfully booting the set-top box. And this is really a problem. The serial port cannot then be used in any way under the Linux system, after the set-top box has been successfully booted. This serial port is only "service port" and is active only during the booting of the set-top box. After that, this serial service port is supposed to shut down.
It is an RJ12 connector on the back panel of the Vu+ Zero 4K. And... of course, the pinouts of the RJ12 connector are connected correctly.
I made the RJ12 <-> RS232 adapter myself and it also works without problems on my other set-top box: Vu+ Solo SE V2 (in this set-top box, the serial port works even after booting and while the set-top box is running, as a full-fledged serial port in the system).
I am using the build:
OpenATV 7.3
Linux kernel 4.1.20
ARM chipset
Does anyone know a trick or an unofficial third-party driver that can enable the serial port on the RJ12 connector in the Linux system on the Zero 4K set-top box, even after it boots ?
Thank you in advance for any advice.
