January 23, 20251 yr 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?
January 24, 20251 yr Author 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`.
January 24, 20251 yr 12 hours ago, leon22 said: I switched to dietpi 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.
January 25, 20251 yr 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
January 26, 20251 yr Also we fixed TUI / GUI way of setting UARTS, merged today: https://github.com/armbian/configng/issues/360 https://github.com/armbian/configng/issues/344 fixed with https://github.com/armbian/configng/pull/393
September 1, 20251 yr Overlay was renamed at some point to just uart5 `/boot/dtb/allwinner/overlay/sun50i-h616-uart5.dtbo` (without `ph5`), so `overlays=uart5` works and is available at /dev/ttyS1
