Hi Steve,
Now i'm using a parallel port interface too, a wiggler clone from olimex with a small modification..... and it works ok with openocd as a server ...
You can find some info to "
http://www.yagarto.de/" site and some other openocd site.
Since the parallel port is not so fast (i see often near to 55Kbits/s of dowload speed, from gdb report.... so it's similar to download using a 115200 uart) i'm developing a small USB interface ..... but i fall into some trouble to find the correct connector ....
As soon i get some spare time i will restart the interface project.
Currently i'm using the GVD debugger connected to GDB.
Currently i've made some test with CodeBlocks and GCC compiler for NEC V850 and i'm going to test also ARM7 compiler ...... GVD is simple to use and stable enough but there are problems on c++ files ..... so codeblocks could be a good substitute ...
Some times i'm thinking to a serial remote stub useful to download the program directly to the flash mem...
