Regular ContributorHi,
Can you load the preloader first to make sure the SDRAM has been calibrated successfully? Only then you are to create and apply the scatter file, since the SDRAM has been brought up from preloader.
Replying back to your first posts, can you direct me to the TR-manual which demonstrate the scatter file that you mentioned?
This is the link to locate the bare metal application in the SDRAM by creating a new scatter file, is this the examples you tried to follow?:

Occasional ContributorHi,
The scatter file was being written by me after reading the default SDRAM base address (starting) and ending address in MPU address space. I am first loading the preloader and then trying to run the bare-metal.
I have already followed the aforementioned example and its not working.
After, making some changes, now my preloader works fine without error; but still the bare.metal program doesn't load from the SDRAM.
Here is the output in the terminal (for preloader):
