Hi,
I'm trying AN2557 FW3.30 from ST's website. i run it and I fill it succesfully when download first application at 0x8003000-0x8004209. but for second time, the downloading is failed.
then i go to check flash contain, and i saw
the address 0x8003000-0x80037FF = still fill with data (i'm not sure is this from last application or new)
0x8003800-0x8003BFF = Blank (0xFF)
0x8003C00-0x8003FFF = Data Contained
0x804000 - .... = Blank (0xFF)

what is the mistake?
Thanks in advance.
