Hi every1,
I have a question, which PC/linux software is the best to debug the 
LPCxx via the JTAG I see that the wiggler has software but this 
includes cross compiling tools, any stand alone software ?
Also I don't have a wiggler or similar but I have a nice FPGA so does 
any1 have VHDL code for RS232 <=> JTAG or LP <=> JTAG or some notes 
on the protocol timing requirements etc....? 
Happy Programming.
Regards Billy
