How do you download the blinky project to the evaluation kit board?

Alison

I have the nrf51822 eval board and I am just trying to download the blinky project. I have followed the quick start instructions in the nrf51822 user guide but every time I press download an error message pops up saying ' No Cortex-M SW Device Found' I have tried changing some of the settings in the options for target device but now a different error message pops up saying 'No CPU DLL specified'. Can anyone help?

    Hi,

    Most likely, your board has gone into SYSTEMOFF mode. In this mode, the DIF (debugger interface) is detached, and you cannot flash. Try unplugging the USB and reconnecting it, and try to flash your application then. If that does not work, you can use the "recover" option in nRFgo Studio.

    The new error message you are seeing " 'No CPU DLL specified'" indicated that your project setting has been altered. Try with another example, or "restore" the specific project that you have.

    Best regards Håkon
