nrf51422 doesnt work

[Jesus]

Hi. I have a nrf51422 EK. I follow the steps in nrf51422_Evaluation_Kit_User_Guide v1.1.pdf but I couldnt do blinky_example project to works. In debugger mode, I see that the code is always in an infinity loop, in 0xA0E0 addres. I changed IROM start to 0xA000 from 0xC000 and the blinky_example works fine.

I followed the user guide and tried to run broadcast_tx. My device is always in iddle state and doesnt work. If i try to debug i can see that it is always runing in the same loop, "HardFault_Handler" is the name of the loop. I need help to make my device work, please.

I used: nrf51422 FW: s210_nRF51422_2.0.0.0 nrf51_sdk v5.1.0 Keil uVision5

thanks.

EDIT: I just saw that I should use SDK 4.X.X with my version of the nRF51822 chip. BUT i cant find this SDK version. ¿Any help plz? thanks.

You can access previous versions of a download by clicking the version number in the download list. The previous SDK is hence available here as an installer or here as a zip file.

Thanks. I had not acces to your link. But It allowed me to find the correct site. Now all works fines with SDK 4.4.2, blinky_example and broadcast_tx. Thank you again.
