  • Glad to be of service. I always nowadays try to use the free development tools or Keil. Not for shorter funds, but more and more pro's use the free dev.tools.
    Did You manage to integrate the JTAG(try the OLIMEX) parport dongle interface correctly(with the Zylin plugin)?

    I use a ST Cortex-M3 dev.board (just like a Intel bootstrap). Some compilers will do that for You, but where's the fun then? The rest is quite straightforward.
