RT1021 reallocate FlexRAM

Hi, @jingpan

I saw that you mentioned some issues related to reallocating FlexRAM, now I have some questions to ask you after reallocating FlexRAM.

1.Reconfigure the register in startup_mimxrt1021.c, DTC->128K, ITC->64K, OC->64K

2.Modifying memory size

3.Modify stack. And adjust the stack space is greater than 64k

4.Add ResetISR to the vector table

5.Modify MPU configurations

But, when the stack space is greater than 64k,the program won't run.

Hi @jarman_zhou ,

It seems fine. I made a same demo, it can work on my RT1021 EVK.
