Can't program nrf51822 with keil

milad sharbati

Hi everyone,

I want to program the nrf51822 module with the discovery board stm32f429i-disc1 through ST-LINK programmer in Keil IDE but this error appears: "ST-LINK connection error".

I erased the chip with ST-LINK Utility but in Keil, I can't. Is it feasible to program nrf51822 with Keil or I should choose another platform like nRFgo Studio? If the answer is yes, how should I fix this error? I'm using SDK v10.0.0.

Any help would be really appreciated.

Regards,

Milad.
