i have given small delay in mpu section and now it is not stuck when power is on and off.

void mpu_setup(void) {

nrf_delay_ms(25);

ret_code_t ret_code;
// Initiate MPU driver
ret_code = mpu_init();
APP_ERROR_CHECK(ret_code); // Check for errors in return value

// Setup and configure the MPU with intial values
mpu_config_t p_mpu_config = MPU_DEFAULT_CONFIG(); // Load default values
p_mpu_config.smplrt_div = 19;   // Change sampelrate. Sample Rate = Gyroscope Output Rate / (1 + SMPLRT_DIV). 19 gives a sample rate of 50Hz
p_mpu_config.accel_config.afs_sel = AFS_2G; // Set accelerometer full scale range to 2G
ret_code = mpu_config(&p_mpu_config); // Configure the MPU with above values
APP_ERROR_CHECK(ret_code); // Check for errors in return value

}

@Rahul I agree with RK. It would be very useful if you could post a more detailed solution to help other people that have a similar problem in the future. Just post it as an answer because people have a tendency not to read the comments & only focus on the answer :)

so how about posting a 10 line answer which explains what the problem was so the next person with a similar issue can find it and solve it. "some power issue" doesn't really tell anyone what you found. If you can spell it out in more detail it helps the next guy.

Which mpu code are you referring to? Is the mpu_simple example found on Github? Are you getting any error messages?

i am searching sir and trying to get all info from there only but as i am new to programming that's why i am facing more problem. i got what is the problem but it was in crossworks. but i didn't find how i can do it in keil. i am doing all the things that i can do and still trying

clearly you didn't bother to search or you would have found that startup from reset is an SES thing so that's not it since you're on Keil (which is new information as usual)

Search for another person who was having issues because they'd put the UART into blocking mode and was using it for debug.
