An issue has been seen with the stm32lx flash driver that if a power cycle/reset is applied after a erase, any ram loader will Hard Fault on execution. A similar issue is mentioned in the errata for the device. Two solution's seem to workaround this issue: 1, Handle the exception, this means adding exception vectors to the loader and changing the exception address using nvic vtor register. 2. falling back to using slower direct page writes - approx 50% slower. Using solution 1 would mean restrictions are placed on the loader location. Solution 2 was chosen mainly as it was simpler too implement.
