Hi! I just got a couple of Jupiter 2 boards in. The preinstalled Bianbu is nice, but I need to figure out how to put my own OS on it before I can use it, and I’m also going to want to build custom versions of all of the low level firmwares I can get sources for. It seems that most of those sources are available, and I can probably figure it out as I go, but I need to be ready to un-brick if anything doesn’t work on the first try.
Looking at the K3 datasheet, it seems there is an option to boot over UART, but I’m not clear how to trigger this on the Jupiter 2 board. Can anyone give me any guidance on how to put the BootROM into the boot-over-UART mode?
Thanks!
