Re: Connect OpenMV H7 to BeagleBone Black

BeagleBone has serial debug header, I have thought that with this connection The ttyACM0 in Matlab would be worked..

I am using only Matlab and beaglebone,
or SSH connection with Putty- to find out Beaglebone data (dev. names, etc...)

So the Serial Port is needed to open by any program ??

Re: Connect OpenMV H7 to BeagleBone Black

serial - not work
But i found "ttyACM0"

do you think, that I should connect OpenMV cam to Serial Debug Port on BeagleBone black with FT232 USB to TTL Serial Converter Adapter Module ?

because there is Error: Cannot query '/dev/ttyACM0': System returned (25): Inappropriate ioctl for device.
