Question: XPROG (both V5.5 and China clone 6.12) don't read all bytes. It reads only unsecured bytes (pages). I try Windows 7 32 and 64, and Windows XP. The insecurity zone is only FF.
I think that problem is not in the ECU and connection, but in XPROG and MC9S12 secured MCU, because I read this MCU with VVDI prog without problems.

Good to know:
Advice: I think the data read by Xprog are OK, sitting at the right memory blocks but the final file size is much bigger than VVDI.
For example, MC9S12DG256, Flash file has 2 MB of reading by xprog while just 256 if read via VVDI. Someone already compared these two data outputs, please?
+ 1:
I did once. The size difference is because the Xprog reads the MCU like it was designed by factory. In the window where You choose the MCU family to program, You will see in info, that there are some addresses, that are excluded from memory.
VVDI Pro and Rosfar read only the memory containing DATA, Xprog reads whole, as well as the blank (FF) spaces between data fragments.
In Xprog ori software there is a button "Editor Tools" There is an option to convert the files. You can convert the 2MB file to the 256/521 and program with VVDI or Rosfar (it just deletes the FF from blank areas) and vice versa, there is an option to automatically add the blank spaces, and then program file from Rosfar or VVDI by Xprog.
