Okay, I've got the classic dilemna here. As of Friday, we have to build something quickly that works well and costs little. I have to put together a software solution for a small quantity (300) product using a Coldfire 5282.
It will sit between an IP network and a legacy serial interface, converting from one to the other. I have a couple of interrupt drivers to write that have to respond in the 10-20 usec range. For cost reasons, the software footprint is restrained to the internal
5282 memory only (512k flash, 64k ram).Netburner looks good, but $24.5k is way too steep for this inexpensive product. ThreadX and NetX are the same price. RTXC Quadros is either free for a limited version, $17.5 or $31k. Obviously the free version is attractive, but not sure it will do what we need. I'm looking at Sciopta right now.
Enough rambling. Any opinions or ideas are welcome.
Thanks,
Casey
