Hi! Who can explain this? 743VIT has 2M, it is ok, no questions. 750VBT has 128k flash. How is it possible to program it with 400k+ of code? Or what am I missing?

750 and 743 have 2Mb flash, but in 750 have software block all bank over 0s. ST-LINK utility flashing all 2mb and you can use ful size of internal flash.

Thank you for answer. I thought memory is blocked because it does not work. Can I use 2MB on any 750VBT or should I check it's memory blocks?
