Hello,

I have built the Flashlink JTAG-Programmer according to this schematic:

http://www.st.com/stonline/books/ascii/docs/7889.htm

Unfortunately I always get an error message when trying to program a PSD834F2 via JTAG/ISP in PSDexpress: ''Invalid Port selected. Check also conneciton to Flashlink''.

I used 74LSxx ICs.

Can anybody give some hints, please?

Unfortunately, I do not a have a loopback cable. How do the connections of the loopback cable look like?

Thanks,

preines

ps:i've already connect pin8 &pin 13 from the parallelport-connector
