When using X-cube-sbsfu, why is swap area size constrained to be at least equal to the size of the largest flash sector? Is there a way to modify SBSFU to work with a smaller swap area?
On STM32F746, largest sector is 256K and total flash size is 1M. This means that 1/4th of our flash is lost to the swap area. As a result, we do not have enough flash memory left to implement the dual image variant. We are now trying to optimize the ...
