Thank you for your patience.
In annex I put the *.map file.
this map file is obtained after you have fixed the project
Now I’ve changed the linker to “STM32F746ZGTx_FLASH.ld” and works fine!
Glad to hear that
But I do not understand why this change... why, in a momment works nice, and the next momment all of this goes crazy...
You probably have intentionally discarded the linker settings so the arm_none_eabi_ld have used the default setting (flash at address 0)
