Atarix01

Ok, I will try that. I am going to test the drone tomorrow. I'll tell you what happens 👌

> Please try with latest configurator from https://github.com/betaflight/betaflight-configurator-nightlies/releases and use latest development firmware. I have try with the latest configurator and the latest firmware. The bug is still here 🫤....

Okay 👍. Yes the bug appears only when the GPS is plugged. I'll try to re-flash my FC without OSD_SD and try to fly with that.

So I have tested with BF 4.5 RC2, without OSD_SD and with a new M10 GPS from an other brand ( GEPRC ) and the bug is still here 😭

I'll try to plug the GPS on an other UART to see if it works

The bug is still here even if I change the UART. I haven't anymore ideas to solve the problem, I think I'll buy a new one... Again

https://www.diatone.us/products/mb-mk4-h743-v2-fc It's this one. The flash chip could have an impact, so it's an hardware problem. Can I solve it without buying new FC or solder a new flash chip...
