Hello Karunakaran Radhakrishnan,

As the AN4876 suggests in Section 4.2 Configure initialization file of project for debugging, you need to choose U-Boot initialization file. Copy below:

1. Choose Run > Debug configurations, to open the Debug configurations dialog.

2. Select Project name from the left pane and from the right pane, under Main tab – Target settings, select Edit.

3. From the Hardware or Simulator Connection dialog, select Edit to edit the target.

4. From the Initialization tab, browse to the location of U_Boot initialization file and add its location in the Initialize target.

5. Navigate to Memory tab and deselect Memory configuration.

6. Select OK to exit the Debug configurations dialog.

Regards

Hi Lunmin , Hi Adrian,

Thanks for your reply.

Default Reset vector Address is 0xFFFFFFFC. My Uboot reset vector address is 0xEFFFFFFC.

initialize nor flash in the script and change the PC reg to effffffc.

Now, I can able to debug using the u-boot source in code warrior.

Thanks,

Karunakaran R
