I am using OpenOCD for programming flash memory of STR710 via a wiggler JTAG interface. It might be tricky to set up, but it works.

You should consult the docs that come with OpenOCD. That's what I did, anyway. In short, there are several steps involved:

1) From command line, switch to OpenOCD bin directory and launch ''openocd-pp.exe -f config\str71x.cfg'' (most likely I misspelled the file names, find them in your OpenOCD setup)

2) From another console box, connect to OpenOCD with a telnet client: ''telnet 127.0.0.1 4444''

3) Now you have the OpenOCD command line. The command ''flash erase 0 0 9'' will erase all 10 sectors. The command ''flash write_binary ...'' will program a binary image. ''help'' gives a list of commands. ''help flash'' gives info on flash commands.

It is possible to automate those things with a script.

I might have modified the default .cfg file, can't remember.

I downloaded OpenOCD from YAGARTO home page.
