Can't enable UART overlay on OrangePi Zero 3

Armbianmonitor:

I see the device tree file here:

```

/boot/dtb/allwinner/overlay/sun50i-h616-uart5-ph.dtbo

```

But after adding `overlays=uart5-ph` to `armbianEnv.txt` and rebooting, I'm not getting any new serial device created.  Any idea what I need to do?

For anyone else searching for a solution, I switched to dietpi and now the `overlays=uart5-ph` actually works and I can access it via `/dev/ttyS1`.

That is almost a binary copy(cat) of Armbian, assembled in different time. They (he) don't credit where they get close to 100% of the value that makes those boards run. I am sure you can find Armbian, perhaps previous build, where this problem is not present. We developed and maintain all those features, while project you are recommending is yet another reason that kills motivation of open source developers. People you need most. 

Diepti is a person that downloads Armbian and sells it under his brand name to make some profits, while we are project asking you to donate, so we can get at least 0.5% of our costs covered. Code you are using was developed by us, bugs are usually the same. And there are so many bugs in common code, where Dietpi does not contribute, that is impossible to follow. He didn't fix this, we broke this recently and he didn't copypasted those bugs from us yet.

 

We do this https://docs.armbian.com/Release_Changelog/#v24111-2024-11-28 every 4 months. In past 10 years, we would hardly find records in any logs from their side. Please don't recommend such projects here even if it (randomly) works for you. If you don't support our work, for your and copycats behalf, at least do that.

 

Solution to a problem can be found on forums as you are not the only one. With a bit more patience.

Hi

 

I use Orange Pi Zero 3 with ArmBian Bookworm and in armbianEnv.txt I have

 

overlays=uart-ph5

 

and I use /dev/ttyS1 which work good for communications with hardware connected to this serial port

 

dmesg |grep ttyS1
[    1.376441] 5001400.serial: ttyS1 at MMIO 0x5001400 (irq = 298, base_baud = 1500000) is a 16550A

Also we fixed TUI / GUI way of setting UARTS, merged today:
