Hi all:

    We got one problem that our EVK board can not execute from SDRAM.

 

Chip: I.MX RT1020

SDK:  SDK_2.5.0_EVK-MIMXRT1020

 

example_1(SRAM)evkmimxrt1020_freertos_hello
example_2(SDRAM):evkmimxrt1020_hello_world
All the example used above are the SDK demo examples.
example_1 memory configure:
This example can work well in our EVK board and the MIMXRT1020-EVK too.
example_2 memory configure:
This example still can work well in the MIMXRT1020-EVK ,but goes wrong in our EVK board,and the error show as below picture:
What should we try to fixed this problem? Or is there something goes wrong with our EVK board?
 
By the way,I want to know one question that can we use the MIMXRT1020-EVK SWD port to debug another board.
just for the normal programming and debugging.
Try as below figure:

 

 

 

Thanks & Best regards!
