Arducopter doesn't start, missing pwmchip0/duty_cycle

hello - i’m having trouble starting ardupilot out of the box on a Raspberry Pi 3 B+ using the unmodified image downloaded from (http://files.emlid.com/images/emlid-raspbian-20180525.img.xz)
running emlidtool produces the image attached

pi@navio:/sys/class/pwm/pwmchip0 $

note: the voltage warning in dmesg occurred when i pressed on the header to make sure the hat was screwed on tight, which it is.

this is actually my second attempt at booting from a downloaded/flashed image. on my first attempt the same sequence occurred (same image!) and i installed some prerequisites, downloaded the examples and was able to get output what looked like live readings from the gps (python an d c++) the baro sensor, and multicolors from the led, although the 3d imu tool does not move when the pi is moved around.

when there is no sd card in the pi and power is applied the green led lights. currently after having run the emlid tool and failed to boot arducopter there is no green light.

please advise

actually just found a post that called for this and it worked like a charm
$ emlidtool rcio update

successful connection to gcs thereafter.
