Hi bilge kara,

Please check your MIMXRT1020-EVK board back side, find the SW8, power off the board, then change it to:

SW8_1 OFF

SW8_2 OFF

SW8_3 OFF

SW8_4 ON

Then use the USB cable connect j23, connect the debug button on the MDK, I am using the SDK code:SDK_2.5.0_EVK-MIMXRT1020\boards\evkmimxrt1020\demo_apps\led_blinky\mdk

This is the test result:

You can try it on your side.

If you want to download to the external qspi flash, choose this item:

Then press the LOAD button, after the download is finished, then power off the board, change the SW8 to :

SW8_1 OFF

SW8_2 OFF

SW8_3 ON

SW8_4 OFF

Power on the board again, you will find the on board D5 is blinking, it means it works OK.

Please try it again on your side.

If you still have question about it, please kindly let me know.
Have a great day,
Kerry
