Hi,
I started with Flight Controller KakuteF7 but needed EKF2 module to fly position and offboard modes. I tried to make space to fit the code in flash by modifying default.cmake file as stated here : https://github.com/PX4/PX4-Autopilot/issues/16209.
However, some modules are mandoatory for my use case so I decided to replace the MCU of the KakuteF7 (a STM32F745VG) with a STM32F765VI pin to pin compatible but with 2Mb of flash instead of 1MB.
I am encountering a problem with the firmware : using QGC flashing firmware from stable release (V1.11.3) is OK and the board seems to work well. When I compile firmware locally, without modifying any file (just running “make holybro_kakutef7_default upload”) the firmware is uploaded to the board but crashes after few seconds, USB is no more detected (device manager display : unknown USB device).
Has someone encounter a similar problem ? And has someone ever replace a MCU from a FC ?
Thank you for your help.
