nrf51822 oscillator requirement for flashing

Flagada15

Hi all !

Can you tell me if it is possible to flash a single nrf51822 ship directly or if it requires at least the minimum oscillator X1 in order to be flashed?

The reason I am asking is that I tried to sold a nrf51 on a home made pcb and currently with only the ship it doesn't seems to work but I don't know if my soldering is the cause, or if I burn the ship with the hot air or if I have to sold additional capacitor and quartz in order to be able to flash...

Thanks in advance for your response !!

    Thank you very much for your answer, still not making it works but I will find :) It's a good thing that we can test the ship before to solder all the other components ;)

    I am using a nrf51-dk via the p20 port to flash the standalone ship, what JLink command you would use in order to test the connexion? On my side, when I try to upload the .hex file I just receive a FAIL.TXT file saying "Error while connecting to CPU"...

    It's very hard. I'm using a home made reflow oven and I've got 1 of 3 fully soldered the first time, one of the other two I never got to work and the other one I got working after a lot of messing about with hot air. I actually just ordered a stencil to try and make this a bit easier.
