WMX sendcode

Abstract

WMX sendcode is a program that uploads code to DCT3 series (noticibly 3310, 3330) RAM instead of flash, it includes simple host debug packet interface to facilitate for experimenation and timing.

It's not exactly fluffy or user-friendly, but it works, and that's the only thing that matters right now. If you've got so far you actually need this program, you're probably not scared of a bit of C code anyway.

Compilation

It should compile under Cygwin and Linux. Although I haven't tested it in Cygwin. If you port it to something else please send the patch to me.

$ cd wmx-sendcode
$ make

Usage

$ wmx-sendcode/sendcode NHM-5 mycode.bin

Make sure you have the approciate I/O permissions for direct Parallel Port access, under Linux this means root, under Windows it means you have 'userport' running.

If you have questions mail me.

The code

• Origin is 0x00000000
• First four bytes = entry point (00 00 00 20 mostly, because you want the interrupt vectors ..)
• Entry point must be ARM, of course it can immediatly jump to THUMB if it wants
• Code block must acknowledge (Set SDA to 0, that is I/O 0x19 to 0x00)

Have a nice day.
