You might want to make sure that you are using the BMP280 in I2C mode, instead of SPI mode, as it supports both. Before assigning a driver to it (your echo command), you can try to see if it's actually being detected on the i2c bus and dump its registers using the i2c tools (i2cdetect, i2cdump) You also didn't mention what linux/kernel versions you are running. There's support for BMP280 on newer linux kernels within the kernel iio framework as of 2014/2015. regards, Nuno -- -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
