AM62L: AM62Lx: DDR Configuration and APP Boot from SPI Flash (FreeRTOS/NoRTOS)

Part Number: AM62L

I am using the prebuilt tiboot3.bin to boot my FreeRTOS / NoRTOS application from SPI Flash on the AM62Lx EVM.
 
I noticed that there is no DDR initialization example or demo provided in the AM62L-FREERTOS-SDK. I have 2 questions:
 
  1. If I keep the same DDR4 part and size as the EVM board, do I need to perform DDR initialization in my application?
     
    Or can I just flash my application binary to offset 0x80000 and run it directly?
     
  2. If I use a different DDR4 part or different DDR4 size in my custom hardware, what is the correct way to handle DDR configuration?
     
     
     
 
Thank you very much.
