Dear PGO, how can I read the flash content of that DSC? I saw that it's in list of MC56F programmer, but not in Memory dump.
The support for MC56F device in USBDM is very limited.
The device family is very different from the other supported families and it has a lot of "special case" code that can't be shared with the other families. The effort to add new devices is quite high.
For both of these reasons I have done little recently to support these devices.
I will have a look at how difficult it would be to add basic MC56F support to the memory dump program but it is unlikely to be any time soon,
