PRU Approach¶
Dieter has had the idea to build this using the PRU unit[s] of a TI AM335x processor.
The idea would be to at least prototype using a beaglebord + the PRU-Cape
The main differences of a PRU based solution compared to XMOS are:
+ | could run OsmoBSC or OsmoMGW or whatever one would want to run on the ARM core |
+ | can directly provide Ethernet, so no worries with custom USB drivers on Windows (Dieter) |
0 | no need to learn about XMOS programming (But then, PRU programming...) |
- | need to investigate Linux kernel interface to PRU (remoteproc, rpmsg, virtio) |
+ | not having to rely on exotic low-stock part (XMOS) |
0 | both variants could be produced in series |
- | LIU+XMOS likely lower cost than AM335x-SOM+LIU |
- | not possible in a "USB Adapter form factor for usb-powered use" with Laptop or as general peripheral. Well, actually, yes, using USB gadget on the AM335x, but it will be rather large |
where "+" means advantage for PRU, while "-" means disadvantage of PRU compared to XMOS. "0" is neutral.
