One key parameter in Milestone 1 is to investigate and confirm that it IS possible to do it on Linux.
1: A hardware that can support dual USB ports, on running in UFP and DFP. As far as I know, most embedded MCUs (and maybe Linux CPUs?) have a USB port that can be configured for either mode. Need a HW platform that have two USB 2.0 ports, with one configured as DFP and one as UFP
2: That the Linux USB stack, on the USB UFP can expose a virtual USB hub and it is possible to attach viritual devices on that
3: That you have the C competence to implement this
if you find that running an embeedded track instead of Linux is better, we are open for that as well. But need an MCU that can channel the full 480Mbit/s through it.
Both FreeRTOS and Zephyr or ok to use |
