Maybe you could make your sourcecode available? I'm thinking
about porting a jtagtool like "jtager" to eCos as host and as
a result I want to have one day an JTAG adapter which could
in the first step only burn FLASH via JTAG, but in a second
step could also debug the target.
Therefor it should talk the gdb remote protocol. Having
special support for operating systems for multi threading
would be perfect.
