/dev/i2c-4
I am referring RedSensorToCloud-master example from mangoh red github.
on executing (with some changes).
error:-

Do i need to load bmi160 kernel module into my legato system?
can someone help me with that?

It looks like you’re not running a system based on the mangOH.sdef from the mangOH git repository. That SDEF includes kernel modules which for the I2C switch (address 0x71) and the bmi160.

I followed steps on mangOH Red Getting Started Guide (Linux) [Rev5]
and created mangOH directory as per instruction.
When i execute the command " make red_wp76xx " it gives me error

It seems like you don’t have g++ installed.
