When I program from a System ACE MPM device containing 5-8 configuration data sets using an .mpm file generated in 4.2i/5.1i, the software fails.
(This does not affect .mpm files that contain only 1-4 configuration data sets.)
This problem is fixed in the latest 5.1i Service Pack, available at:
The first service pack containing the fix is 5.1i Service Pack 1.
NOTE: If you are using multiple configurations, and you change the BITSTRSEL[0:2] lines, you must pulse the SYSRESET or FCM_RESET or cycle the power to the board to activate the file for a new data set from a different location.
