STM32F765 Dual Boot issue. FW reboots when I enable dual boot, but issue goes away with dual boot disabled.

Been trying to debug this issue and so far I haven't come up with an idea on why the system reboots due to a SW reset. (It acts like I have a watchdog enabled since it will reboot on any HAL_Delay loop) (Reset reason is 0x1400 0000)

Been wondering if the CPU is even supporting the Dual Boot feature since I see the 1M part doesn't even show the dual boot bit in CubeProgramer while the 2M part does. But both seem to have the issue with the SW reset.

Some info about the CPU settings

I have BOOT_ADD0 set to 0x2000.

Dual bank and dual boot are both set to 0 while the rest of the option bits are left at default.

The protection level is left at default.

Also attached is a cube file that I have used to to create the issue.

    Hi RMedi.4,

    I have exactly the same issue. Did you have any luck fixing it?

    Best regards
