Is this bug report about any UI component firmware like InkHUD or Meshtatic UI (MUI)?

• Meshtastic UI aka MUI colorTFT
• InkHUD ePaper
• OLED slide UI on any display

Firmware Version

2.6.11

Description

For context:

I have been unable to flash the Heltec V4 software on the V4 board, in the interim I have flashed the V3 software onto the V4.

(Issue noted in 8543)

I added the L76K GPS Module from heltec to the V4 board, to which while it is plugged in, it fails to boot.

I am assuming that having the V4 GPS module running on V3 software is not conducive to it working properly.

In this case, I know I've essentially answered my own question but wanted to bring attention to it since V4 flashing isn't working and I have no other way to test the GPS module in meshtastic otherwise as using V3 software has been the only working flashing methodology for me.

Relevant log output

[b8b8]

The Heltec V4 is newer than the 2.6.11 firmware.

No prior firmware actually exists for as 2.6.11.

Load firmware 2.7.13.

Dont flash the wrong V3 firmware on the V4. The pins are different.
