I'm doing a project that use all resources and options available in stm32f746 using its discovery board to create a smart controller I did not reach half distance of my road and now the zi data is around 390 kb which is greater than actual device RAM My question is does zi mean real places booked in RAM or just virtual according to program and when program run it will be deleted and over written like what happens in stack and heap ? If yes real location then how is program still run and it show zi greater than device RAM Note1 there is external RAM used for LCD buffering How I can use that external RAM to increase total RAM for zi Note2 I'm new in C and arm
Thanks
THANKS I got the problem from original LCD driver it define lcd buffer as static array with size round 260 kb in external ram once i make as pointer it reduced that amount
