I am working on STM32F765BIT MCU with our custom board . In our board NAND flash is connected to Bank3 (0x80000000 - 0x8FFFFFFF). I configured using STM cube and just tried to read device ID but MCU is getting locked once I did that. Simply two MCU are locked while doing these experiment .
I found that even internal Flash is also sharing same space, if so how can I access external NAND flash. Can anyone give some brief explanation how do I access external NAND flash. Is there any method to remap internal flash to other space. I just want to read/write external NAND flash for the first stage.
Also suggest is it possible to reuse those MCU once after locked, if so how to unlock those MCU.
