Booting after flashing

Question

Hi, this is Santhosh. 
 I write an application code regarding image processing and used there DDR2, it is running well after debugging in the tool. So I flashed it in W25Qxxx flash memory but after restarting, it is not running. I didn't get where the problem is. Can you please help me. 
 Note:- Some codes without using DDR2 are working well after flash in the same W25QXXX.

Hi Santhosh,

1. Are you including the INIT file while creating the loader file? Initcode is mainly used for DDR initialization, changing CGU settings. If you are using external memory, please add the INIT code and check whether the booting works.
2.Please try to connect the processor in DND(Do Not Disturb) mode and check. This would help to isolate whether the issue is with booting or the application. Please refer the below FAQ for connecting the processor in DND mode.
