Reseting all MPU9250 Register problem

By theorizetest123 , 16 December 2015

Hello everyone,

i want to reset all registers to default state. To reset the registers, i send the byte 0x80 to the register PWR_MGMT_1(Registeradress: 0x6B, Dez.:107). This register is described in the document MPU - 9250 Register Map and Descriptions Revision 1.4 at page 40. But it doesnt work. All registers have the same data after reading them.
Picture of the data send

When i read the registers after sending the MPU9250 this data, the registers are not i default state. For example: i wrote data in the registers XA_OFFS_H, XA_OFFS_L, YA_OFFS_H, YA_OFFS_L, ZA_OFFS_H and ZA_OFFS_L (MPU - 9250 Register Map and Descriptions Revision 1.4 page 44f.). After reseting via I2C the registers have the same data. Thank you for your help.

greetings from Germany
