Hi all,

i’m getting messages about i2c devices not responding:

[ 1699.161350] tegra-i2c c240000.i2c: no acknowledge from address 0x1c
[ 1699.167927] tegra-i2c c240000.i2c: no acknowledge from address 0x1d

I have i2c access from user space , using imu with rtimulib with no issues.

running sudo i2cdetect -y -r 0 shows ‘UU’ on address 40h,41h,42h,42h,75h,77h
same command on i2c bus 1 shows proper IMU address

I assume the 2 devices are related to the dev board?
