Yes I figured that memory is the key issue!
When I was trying to implement the project with Keil I noticed that if I
allocated too much memory to heap or stack (heap mostly because of the
malloc calls) I was getting overrun behaviour from the ADC and transfer
errors from the DMA just after the code turns on the ADC.
When I decreased the Heap allocation to something more modest that
behaviour stopped.
Which I think is what's going on with the OFDM mode if you try getting it
to work as it is right off the bat on the STM32 but funnily enough when I
tried debugging it and noticed register values for the ADC and DMA they
both seemed to be working properly which I found very strange.
