After a success CRT (GYR_GAIN_STATUS.g_trig_status reports a successfull CRT run), I tried to get the new gyro gain values from below locattions:
- register 0x78, 0x79, 0x7A
- GYR_GAIN_UPD_1, GYR_GAIN_UPD_2, GYR_GAIN_UPD_3 in page 1
But all values are "0".
I wonder how to get the new gyro gain values, wihch will be programmed to NVM later. Thanks.
Solved! Go to Solution.
Also, there is no description about registers 0x78, 0x79 and 0x7A in the BMI270 datasheet (two versions, see below).
Could you pass me some datasheet description of registers 0x78, 0x79 and 0x7A? Thanks.

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.
