And I am using a Lauterbach ICD for such purposes without any major problem. I can't see a reason why there should be a problem AFTER reading the documentation. In my eyes it doesn't make any sense to use a tool like a JTAG debugger without understanding how the systems works. So if you get initialization scripts from someone else and don't understand them you also won't understand how to debug your bootloader(s). In many cases you won't be able to find all bugs when just stepping through the code on C language level. But if you understand how the processor works you won't need anybody else providing you with further information/files. Why do so many people think that mailing lists like this are a total replacement for RTFM? With best regards Andreas Schweigstill -- Dipl.-Phys.
