Hi, Usually you would need an infinite loop in main, not to return. But it may not fix the issue here.

I'm no expert in nRF9E5, as it's pretty old chip. Our expert on the chip is on New Year vacation now, we will get back to you next week.

I wrote just short simple program which Output a pin high in keil and created Hex file. Here is the program :-

  <#include <Nordic\reg9e5.h>

   int main(void)
  {
       P0_ALT = 0x00;     
       P0_DIR = 0x00;  

   P03 = 1;
 
	return 0;
   }>

Then I used eeprep tool and set above given options and created a EEPROM file with 3 bytes in header and then I used Hex2Bin to create Bin file and uplaoded that in 25AA320 EEPROM IC. But the Led doesn't glow. What's wrong? Please help

Hi, you should use:

eeprep -c 16 -i -p 4096 -s intput_file_name.hex output_file_name.hex

Make sure you have the permission to write to that folder.

I made some mistake in eeprep tool. I used command like this in command prompt :-

eeprep [c16,i,p4096,s] <nordic.hex> <nordiceep.hex>

Am i doing right, is the format correct?

Thanks for your answer. I wrote a blink program in Keil and used eepreo tool to add 3 bytes. What to do after that? It's in hex format but to program EEPROM , it must have Bin file. What to do?

Hi,

You may want to have a look at the answer here.

Note that, according to section 21.2 in the product specification you need to have 3 configuration bytes in the start address of the EEPROM. You can use eeprep tool to add these bytes.
