stm32f4 memory length

[groups at chichak.ca]

According to the STM407 users manual:

There is 112KB at 2000 0000
16KB at 2001 C000

And the final 64K is at 1000 0000

So your memory isn’t contiguous at 2000 bazillion. When you declare that it is, the memory test will get into an unused space and give you an address trap.
