Which to me, isn't a lot of help. But, thats broadcom... Too bad I can't put a bounty on them. It seems to me that any outfit with more lawyers than engineers ought to fall over from top heavy and foot damage eventually, but they seem to be the exception to that rule. OTOH, its even harder to get any usable info out of Pine to facilitate using an rtai kernel on a product of theirs called a rock64. Which can build that kernel in under an hour. And it does use u-boot, or claims to. Here we have another credit card sized boy wonder computer thats probably 10x or more faster than a top of the line pi, with a usb3 port, and the info as to how to make it work seems locked in a safe behind non-disses they can't even admit to. Hell of a way to run a train.
