Hi @mahinlma , I think this issue has to be resolved differently, because on some platforms the original code may just work (like U280 where the memory interfaces are DDR0 and DDR1); so the code has to adapt to available interfaces provided by the platform. This requires a bit more work on the notebook changes. I'd appreciate if you could do that change instead; or I can resolve this issue later.

#16 should solve it. Closing.
