Working with reserved memory on LPC1549

[pat_wit]

Hi everybody,

i wanted to ask two questions regarding reserved memory on the LPC 1549. In the user manual on page 13 the memory region between 0x1C02 8000 and 0x4000 0000 is marked as reserved.

Now my questions:

1) What kind of memory is this (RAM, Flash)?

2) What happens if i write/copy data (for example linking process) there?

The questions may look stupid but i am forced to switch MCU regarding the supply difficulties. I am considering two write one FW for two different MCU's and solve it with linking etc.

Best regards,

Patrick

Reserved memory is not valid Flash or RAM. if you write code or data to reserved memory, the code will go to hard fault or unexpected error.
