After this steps, I have this build error:

./tools/configure.sh -l nrf52832-dk:nsh

@maurosollar I think you selected the BMI160 example but forgot to enable the BMI160 driver: CONFIG_SENSORS_BMI160

You also need to enable the right I2C port connected to your board's sensor and use the right I2C pins definition.

Also you need to initialize your BMI160 driver in your board bring-up, see boards/arm/tiva/tm4c1294-launchpad/src/tm4c_bringup.c as reference!

Nice too see another "mineiro" here using NuttX RTOS!!! Welcome!

@fdcavalcanti maybe you also can help here, because you added support to BMI160 on tm4c1294-launchpad board :-)

Thanks Alan, exactly what it says. It worked! I really like NuttX, but I still know very little about this RTOS, before I used Microchip with Assembly. I'm from Minas Gerais Uai, rs.

Thanks a lot @acassis
