I am stuck on this one.
I have an existing upsd33xx design that I programed using uPSDexpress and ST's flash link programmer.
I upgraded to a multi-core processor and now the programmer no longer works.
Turns out that the original driver will not work on anything other than a single core system!

A workaround was suggested in the readme files, it said to removed the original driver and replace it with a new driver (PEPNT.sys).
I have followed the instructions several times but uPSDexpress does not even try to use the PEP driver. It just continues to complain that that JTAG driver is not installed (per the workaround instructions). The new driver is in, and the INI file altered to reflect the new driver.

Has anyone gotten this to work on a modern computer?
