nRF52840 doungle

[harrys]

Hi,

I am working on nRF52840 dongle. 

i am facing a issue with programming. before it i was trying to do it with arduino. i don't know its bootloader gets disturbed. led on dongle is blinking with PWM.

how i can clean chip and program the bootloader OR it is any other issue that can be solved without programming bootloader.

Thank you

Hello Harrys,

Take  a look at this tutorial from Nordic about programming the Dongle. To the end of the tutorial you can see how to program using an external debugger, you can also find the bootloader zip file attached.

Kind Regards,
