stm32F767 SDRAM bootloader

[CFranco]

Hi, 

I am currently trying to implement a bootloader that runs from the internal flash and performs the following functions:

1. copy application binary file to the SDRAM ( 0xC0000000)

2. Jump to main application.

So far I can copy the binary from the external flash to the SDRAM but when I try to jump to the SDRAM I am getting a hard fault error.

I have configured the MPU region to enable all access but I get the same result.

There are 2 points that are for me not clear:

- Does the SDRAM application have to be compiled with a specific linker configuration?

- Do I have to de initialize all the peripherals?
