#define BASE 0x50000000

ptr = (int*) (BASE + 0x714);
*ptr= 0x00000001;
while (1)
{
ptr = (int*)(BASE + 0x508);
*ptr=0x20;
nrf_delay_ms(1000);
ptr = (int*)(BASE + 0x50C);
*ptr=0x20;
}

This code works as expected (for port 0 pin 5). But if I try to register BASE as 0x50000300 and change the pin of the first port accordingly (Listing 2), nothing happens.

#define BASE 0x50000300
ptr = (int*) (BASE + 0x708);
*ptr= 0x00000001;
while (1)
{
	ptr = (int*)(BASE + 0x508);
	*ptr=0x4;
	nrf_delay_ms(1000);
	ptr = (int*)(BASE + 0x50C);
	*ptr=0x4;
}

Mystic. I rerun Listing 2 from a colleague - everything works

Could there be something wrong with your module, or did you test it on the same module?

[Saram]

I tested on the same module. Firmware coincided absolutely. The only difference is that the colleague used IAR om, and I KEIL

Sounds like there is something wrong with your project settings then. If you post your project, I can take a look at it.
