I need someone who can provide me some training on nrf51 microcontroller. I'm newbie with this microcontroller and I'm in charge of some software modifications of an existing project.
My problem itakes place when I download firmware using Keil, If I've ereased previously the chip by means of J-Link Commander, I can download the firmware, but it hangs when executing ble_stack_init(), exactly when calling the sd_softdevice enable() function, an SVC exception appears. On the other hand, if I download softdevice first, I'm not able to download firmware using keil.
I want someone experienced on this microcontroller to provide me some training at this stage of the project, may be we could collaborate further in other projects.
