From my experience, after do CRT, the new sensitivity work on. You could record the 0x78/79/7a value in your file or in BMI270 NVM. If you reset or re-power the sensor, please re-write 0x78/79/7a with the former value. You don't need to do CRT again.
register 0x78, 0x79, 0x7A , exactly is not the new gain for gyro, they are parameters for gain or sensitivity calibration parameters.
if CRT success, it should not be zero
