Don't use core-image-minimal - it won't install modules or DTBs into rootfs automatically. You'd have to install those manually. Or use at least core-image-base or some custom image. > 2.

Please use matching branches - i.e. "rocko" from all branches. There were recent reports that "beaglebone" machine had some boot issues. Use "am335x-evm" instead - it does support Beaglebone. > The USB host does not work. I wonder if I am using a good base to start > with.

I tried both, but USB host working. So I wonder what > is the correct one to use? The defconfig is being selected based on the machine you build for. When building "am335x-evm" or "beaglebone", the defconfig with ti_sdk_am3x_release is used. > Thank you for your help! > > > From: Leo Meza [mailto:[email protected]] > Sent: Wednesday, September 26, 2018 6:28 AM > To: Tsai, Matt <[email protected]> > Cc: [email protected] > Subject: Re: [meta-ti] Poky and meta-ti advice for Beaglebone Black > > CAUTION: This email originated from outside of the organization.
