I configure the flexram with SRAM_DTC: 32KB, SRAM_ITC: 0KB, SRAM_OC: 96KB in the demo code "led_blinky" and working with the i.MX RT1010 EVK demo board.
Here is my main code.
I add the register setting in the function "ResetISR".
I use the following connect script.
Build success with the following message.
