Brownout detector was triggered TTGO Lora32 T3_1.6.1

[robbo007]

Hi guys,
Trying to compile code and upload to my TTGO Lora32 T3_1.6.1. I can compile the source (firmware) without problems and it uploads to my device but when I run the pio monitor command I see I get the error:

So it looks like building the code from scratch is broken. Can anyone assist. Thanks

[robbo007]

Tried building the code again and flashing the TTGO. Monitor displays:

Been a long time since I've thought about this project.

I'm assuming you've seen this ticket already? #110

Unless you have a specific need for Disaster Radio I'd suggest checking out Meshtastic or Reticulum

[samuk]

Although I just spotted @Juul made an update a few months ago: e8cfe8a

Perhaps you could try using one of the releases: https://github.com/sudomesh/disaster-radio/releases perhaps that recent update broke stuff?

[robbo007]

Right I've managed to compile the release candidate v1.0.0-rc.1 seems to work but there are a few errors. Any ideas? I cant see any initial problems but might affect something somewhere?

I think all the errors loook related to OLED stuff? So if that works you should be OK?

Can you send messages?

[robbo007]

Yep, screen displays everything fine. So looks good. Thanks

The only other issue is the SD card. Its a 32GB FAT32 formatted. SD card works and formats fine in other systems.
