nRF52840 doungle

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,

Can you please share which versions of Toolchain manager and Programmer you use?

If you want to clear the whole chip then you need to connect to an external debugger. But if you are looking to make the dongle in bootloader mode take a look into this page.

Kind Regards,
