debug console is not working, after following Boot to SDRAM procedure

[ByoungogCho]

I am working on IMX RT1020EVK board.   To boot  image to SDRAM,  I  followed the step of case 2. Add DCD by MCUxpresso IDE. (boot to Sdram.pdf)

made s19. file, and downloaded  s19 file through  MCU Boot utility 3.24.0 tool

but I cannot look at the message  of debug console...   ,   but I can find  the message, After downloading and booting  axf image file in XIP mode

What is the problem ??

I used  example iled_blinky from SDK.

#include "fsl_debug_console.h"    //-1

int main(void)

{

    /* Board pin init */

    BOARD_ConfigMPU();

    BOARD_InitBootPins();

    BOARD_InitBootClocks();

    BOARD_InitDebugConsole();   //-2

    /* Set systick reload value to generate 1ms interrupt */

    if (SysTick_Config(SystemCoreClock / 1000U))

    {

        while (1)

        {

        }

    }

DbgConsole_Printf("\r\nThis project S19 file create SDRAM boot testing \r\n");    // -3

    while (1)

    {

        /* Delay 1000 ms */

        SysTick_DelayTicks(300U);

~~~~~   //Just 3 line is added on SDK example.

Hi @ByoungogCho ，

I made a demo base in hello_world example. If you use MCUBootUtility to download the s19 following the guide, it can print "hello world SDRAM"
