TMS320F28379D: Problem with erasing and programming secured flash sector from within the secured zone

TMS320F28379D: Can security zones overlap?

Part Number: TMS320F28379D

Hi,

I would like to define two security zones:

Z1 for bootloader that has access to all flash sectors and secured RAM (RAMD0-1)

Z2 for application that has access only to flash sectors it occuppies (it must not read bootloader sectors) and secured RAM (RAMD0-1)

Can security zones overlap or must be disjoined? 

Regards,

Piotr Romaniuk
