I'm running a bare metal software on my BBB. It is started via a special boot-application, a program named "MLO" located on eMMC card which then itself starts my application from microSD card. This is one boot option of the AM3358 and used by default.
Now I tried do to the same with the PocketBeagle, in this case with MLO and my application both on the microSD card - unfortunately it does not work, the application is not started.
My question: is there something fundamental different with the Octavo SoC? And is there a serial debug interface available too, similar to the one from the BBB where I can see some messages printed to serial console on boot?
