Tangara hanging on logo screen, wont turn off until power runs out - villain - 2026-01-29
Irritatingly every time my Tangara breaks it manages to do it in a new way
as title, when turned on my Tangara is hanging on the logo screen, and won't turn off until power runs out. I was having this issue on firmware v1.3.1, I used the CLI to flash v2.0.0 and I'm having the same problem still.

Oh, that's very odd. Have you tried without an SD card inserted, in case that's causing the issue? The best way to debug this would be to get the serial output to see if any errors are logged: https://cooltech.zone/tangara/docs/developer/debugging/
If you can use `idf.py monitor` it should also reset the Tangara so you won't need to wait for the power to run out, but if you don't have that set up you can use any serial console to get the logging, though you'll want to be logging when it starts up to see what errors are logged at the point where it hangs.

just so you know the PuTTY link in the debugging documentation inexplicably leads to an anti-vaxxer site now. would this be the mac equivalent? i should have opened with the fact i'm running osx

Yep, to install on Mac your best bet is to use homebrew:
Code:
brew install puttyRE: Tangara hanging on logo screen, wont turn off until power runs out - villain - 2026-03-01
I've got as far as trying to screen the device using "screen /dev/tty.usbmodem14301 115200" in terminal (I couldn't get PuTTY working) but it throws a quick error (something about resources being busy) then "Sorry, could not find a PTY." and returns to the previous terminal window.
I also tried to reinstall the firmware to the latest version, and I can no longer use the latest version of the Tangara Companion ("You can't open the application "Tangara Companion" because this application is not supported on this Mac." - I'm running MacOS Sonoma 14.6.1 on a 2018 Mac Mini) and flashing via the CLI doesn't work anymore either:
Code:
A fatal error occurred: Could not open /dev/tty.usbmodem14301, the port is busy or doesn't exist.
([Errno 16] could not open port /dev/tty.usbmodem14301: [Errno 16] Resource busy: '/dev/tty.usbmodem14301')I'm somewhat out of my depth here and am not sure what else to try to even get you useful diagnostic information.

I sometimes get a message like this from tangara-cli and have to retry, so just in case you haven't tried doing it again, try that and the issue may go away. I'm not a Mac user, so I'm not sure what would make the port busy (other than more update attempts) if you keep seeing it... I would probably just reboot :x

Unfortunately, the last few versions of the Tangara Companion GUI haven't been built for MacOS x86_64, so you won't be able to flash new versions of Tangara using the companion. There's an issue for that here: https://github.com/haileys/tangara-companion/issues/38
I'm assuming that when you reference the CLI not working, you mean the Tangara Companion CLI, so I'll suggest something else. It's a little more complex, but the "developer's" method of flashing the device is the most comprehensive: https://cooltech.zone/tangara/docs/flashing/#recovery-and-initial-flashing-with-idf-py
Note that it's the "Recovery and Initial Flashing with idf.py" section specifically, since the esptool sections don't flash all partitions, and recent Tangara versions do need to flash all partitions to update properly. I haven't done it on a Mac, but I'm assuming you can get the development dependencies via homebrew or similar.
This would also let you do the `idf.py monitor` that ailurux recommended. You don't need screen or PuTTY with this method; idf.py does it for you.
