nt imu connection problem #44
Description
I built the NT-IMU board exactly per the official v4.2 G4 reference design.
Main board firmware works fine, NT bus has 0 errors, on-board IMU is detected.
The G431 on the NT-IMU boots and runs code, SPI + ICM42688/P work (raw data reads OK), but with the official o323bgc_ntimu_v056e_module_v4x_g431kb.hex the NT-IMU is never detected and NT tunnel always fails.
Could you please help me identify what might be incompatible or missing for this board?
