E²P patch and image upload/download
This feature allows manipulating the entire E²P images and also programming the patch.
10.2.1
Full E²P image operation box
This tab button allows:
•
reading the full E²P image and save it to disk
•
computing E²P checksum
•
comparing E²P to an existing image
•
writing the entire E²P using an image previously saved on disk (performing the E²P parameters and E²P
patch programming in a single step)
•
erasing the entire E²P
Note:
If an E²P is connected, the
firmware does NOT support an empty (FF) image. The E²P must be
cleared using the All 0s pattern. Alternatively, a full image can be written (provided by ST).
Both
Erase
and
Write
operations need confirmation to be saved.
