nRF51802 SDK Flash

[Harshit]

Hi 

I have nRF51802 and I have also downloaded Compatible SDK versions 12.3.0

I want to test out TWI scanner, but to support nRF51802 chipset where I have to change or which target I need to build?

You can run the same code on nRF51802 as you can with nRF51422.

However, the SDK examples are configured for the xxAC variant which has 32K  of RAM, not 16K. So you need to adjust the linker settings so the 16K boundary is not exceeded.

Best regards, 
Joakim

Hi Joakim, 
it worked after changing the linker script


 

 MEMORY
 {
   FLASH (rx) : ORIGIN = 0x0, LENGTH = 0x40000
   RAM (rwx) :  ORIGIN = 0x20000000, LENGTH = 0x4000     
 }
