Updating code in the field

[Pacetech]

Is there a way to get a hex dump of my code so that it can be sent to customers in the field without giving them the Forth source code? And how would it get downloaded to the board?

Yes, we've done things like this before with previous products, but haven't had any specific requests for this board yet.

We could probably have a short source loader.

Another way might be to extract it through the JTAG, and then they cold load it the same way.

Well, its later down the line, but I'm trying to future proof my design. When laying out my interface boards, I was wondering If I should add anything to represent a "programming port" - such as a jtag interface or whatever.

I guess adding a JTAG is a safe bet.

Well, most folks we've seen using this count on the JTAG being on the processor board, and updating to it, rather than extending the JTAG to interface boards. But if you need to move the connectivity to a front or back panel, yes you could connect the JTAG through.
