Hi All, Recently I build a wiggler clone with reference attached schematic(jtagwigglersch.jpg). I using my own lpc2148 development kit, I tried to debug my board with H-JTAG. It is really surprising for me that I'm able to detect the device(please see Connection.jpg) but while debugging the code I using the check option in H-Flasher to verify the connection. It is giving me error: Cant halt target and make it enter debug. If anybody have faced this kind of problem share the solution for this. Thanks, Amit C
IRC the TRST-line is needed too for this controller - (S)RST might not be enough.
Thank you Martin, I Connected a nTRST signal and its working perfectly. Thanks, Amit C
