Hi!
I found a workaround to debug Keil software with H-JTAG(free).
Q. How to configure KEIL(uVision3.51) with JTAG?
A. In Keil, open Project>Options for target>Debug>Use RDI interface Driver>Settings>Browser and search for Yr. H-JTAG.dll in approprite folder.
With a cheap Olimex Wiggler it could work like a true debugger(tracing, stepping and so on). But watch out, unless You're a pro, practice a lot....
I actually used the H-JTAG v. 9 and - beside that Segger couldn't either download or debug my code- I was able to download my code via the RS232 interface and later correct the code until it was errorfree and, again download the correct code.
Don't fret, there's always a workaround cheap JTAG stuff
Godd luck
