DarwinFPV240 no onboard baro detected #11598

Hi there, I already asked at discord, but unfortunatly received no feedback on this issue. So maybe it's more than a well known bug?

Current Behavior

Since weeks, I struggle to get the onboard baro of my DarinFPV "Johny5" / 240" quad working. Still no luck, so I would love to get some help and ideas how to fix it 🙂

The board is not labeled, but the specs mention a BMP240 baro, which I can see on the PCB itself. But when I enable baro, the icon in the topbar is red and the status says nothing on a detection.
This is also true if I switch from baro auto to `BMP280.

Steps to Reproduce

1.Flash the quad with INAV 8
2. Apply 5" presets, do basisc setup
3. Enable baro & reboot

Expected behavior

The baro should be autodetected and give some useful values.

Additional context

Unfortunately I'm not aware anymore if it worked on the shipped Betaflight version and config, but not on the BF 4.5 as well. The original config contained esp. this ressource mapping, which I'm not sure if important or not:

resource PINIO 1 B00
resource FLASH_CS 1 NONE

See status log: https://pastebin.com/CatF6N05
See ressourcelog: https://pastebin.com/dzYgs1nE

So how can I fix or check what causes the problem?

What I tried is to add a GPS with included Baro and Mag (a GEP-M1025-DQ), which works, but unfortunately the module uses a DPS310 chip, which has the same I2C baseadress like the BMP280 and causes I2C conflicts.
