Hi

I use board LPCXpresso54608 board with MCUXpresso, SDK2_2. I want to allocate a buffer in Flash2 memory ( serial Flash). I used the follwing statemant in my code ; __RODATA(Flash2) int roarray[] = {10,20,30,40,50};  When I take a lokk a the map File I see the buffer roarray has been allocate into Flash2 memory but when I download code and start the code the buffer contain all zero. I thought during downloading of code the IDE (MCUXpresso) initialize serial memory with a driver.

Best Regards
