http://www.keil.com/support/docs/2795.htm so is uPSD3354DV-40U6 Rev.C available?
SYMPTOM
In projects using the ST uPSD33xx series devices, the µVision Debugger may fail to halt on breakpoints.
CAUSE
There are a few things that could cause this condition.
The ST PSDsoft utility controls the memory mapping of the device. If this mapping does not concur with the memory mapping in µVision, the debugger will ''get lost'' and won't be able to find the correct locations to place the breakpoints.
There is a problem in the pipeline gates of the Rev-A silicon of the uPSD33xx devices.
RESOLUTION
Compare the memory layout in your PSDsoft project, with your µVision project. Make sure the beginning of CODE space corresponds with the beginning of the executable area on the uPSD device.
Contact ST and ask to upgrade to the Rev-C version of your device
