[Bug Report] Enabling GPS or GPS+Telemetry in Configurator sandbags flight controller requiring reflash of firmware.

[BeauBrewski]

Describe the bug

1. Fresh configure of MatekF405SE works until GPS is enabled in configurator and saved. Then cannot reconnect to fc unless booted in DFU mode and reflashed. Confirmed works in BF. Tried on 0.3.3 and 0.3.4.
2. Fresh configure of KakuteF7 HD works until GPS and Telemetry are both enabled in configurator and saved. One or the other on is fine. Then cannot reconnect to fc unless booted in DFU mode and reflashed.

To Reproduce

1. On MatekF405SE, enable GPS in configurator, save/exit, unplug, and try to reconnect.
2. On KakuteF7 HD, enable GPS and Telemetry in configurator, save/exit, unplug, and try to reconnect.

Expected behavior
Enabling of the GPS or GPS+Telemetry to save without sand bagging the flight controller, and being able to use features to fly long range with GPS and/or Telemetry.

Flight controller configuration
Need diff's from pilots reporting issue.

Setup / Versions

1. FC: MatekF405SE
   GPS: Flywoo GM8 Mini V2
   Soldered to UART5
2. FC: KakuteF7 HD
   Pilot speaks French.

Additional context

1. MatekF405SE works in BF with no hardware changes. Emu was fresh install with no copying of BF diff or dump.

so many targets to confuse.
is kakute pilot using the proper target?
we have

KAKUTEF7
KAKUTEF7HDV
KAKUTEF7V15  (V2 in BF)
KAKUTEF7MINIV1
KAKUTEF7MINIV2
KAKUTEF7MINIV3

[BeauBrewski]

Attempting to verify. Should be the KAKUTEF7HDV.
Edit: Verified to be the KAKUTEF7HDV, correct firmware.

Hello,
Did you find any solution to this ? I have the same problem with KAKUTEF7V15, I have to reflash (0.4.0) because I can't acces fc anymore after enabling GPS.

try KAKUTEF7HDV & let us know.
if still fails, we need to investigate target resources and we request cli dumps of BF vs Emu.

Ahhh I was going to add GPS drivers for those targets I'll fix it later today

hi buddieeees, @Kaiowarez did you get time to add gps driver for the kakute?

[nerdCopter]

@loutwice , which target do you need. i suppose i can look. I have the MATEKF405SE .zip above, that was never tested by anyone. (we need feedback/validation)
