Correct - this is the way how we detect the real memory size of devices which can have miltiple configurations - the memory controller gets programmed for maxium size, and then we run get_ram_size() (eventually repeatedly for differept possible row/column combinations).
Ok, I will do it but only in background... I will propose a V2 and I will crosscheck with previously broken board if it is still the case.
Thanks a lot. Please ping me (if needed PM or on jabber) if I should not react.
Best regards,
