Is debug enabled in Flipper system settings?

Is debug enabled in Flipper system settings?

How is this done?

skotopes commented 7 months ago

Main Menu -> Settings -> System -> Debug

Main Menu -> Settings -> System -> Debug

Thanks, that works. How do I debug the actual app I'm working on, is this possible with stlink?

Edit: Alright I think I have it, from a separate terminal I just issued "ufbt launch". One last question, I don't seem to have debug symbols

Thread 2 received signal SIGINT, Interrupt.

Can you enable this from ufbt build?

Lastly, while I have you here, is there a way to specific a serial port for the cli command?

Is Flipper connected via USB and not in DFU mode?

What do you mean by "no debug symbols"? Firmware's ELF is clearly loaded, since valid stack traces are displayed. Firmware sources are not distributed in the SDK.
