Use DMP of MPU9250

my code is below. git_mpu9250_dmp.zip

Hello.

I use nRF52 & MPU9250. I want to use DMP, but I can't read data with DMP. Because it have failed that writting firmware.

I want to check connect sensor between nRF, I made a code for reading register of "WHO_AM_I". At first time, read "WHO_AM_I", return 0x71. After faild writting firmware, read "WHO_AM_I",return 0x0d.

I wrote firmware below, 16,0,0,70,0,0,0,0,24,0,0,0,2,0,3,0,0... read mem below, 0,83,5a,44,9,46,10,6,0,0,15,bb,48,79,c1,3c...

What was happened?
