Lenny, Hello, so no hands on but I have read about several technologies you may be interested in.
First, TI's starterware, and bare metal should be possible - for this hardware. Also, you could directly run an executable from uboot, which is the first( second ? ) stage bootloader for the beaglebone official debian images. Thirdly . . . remoteproc could be used on a dual core processor to run a / the second core baremetal while the first core runs Linux. Or, so I think I've read. There are also RTOS's out there, and TI does have TI-RTOS i think its called. But not sure if it is capable of running on the sitara processors or not. In other words I would think it could, but have not looked into it. So all this stuff I know of, but not much in the way "how". remoteproc for the beaglebone specifically has been discussed in the past on these groups. But there is not much information out there. A couple linux/documentation text files is all. And of course the kernel source it's self. Anyway, is this the kind of info you're after, or is this too basic ?
