Red LED #43

Open naka53 opened 3 years ago

naka53 commented 3 years ago

Hi, I'm using the nRF52840 for some research and after removing one capacitor, the LED is only solid red. Before that, i flashed the dongle with the blinky program from this Github repository. What is the meaning of the solid red LED ?

@naka53 which capacitor have you removed? It seems the firmware halts. Can you enter the bootloader again?

I removed C6 and C8. I'm not able to enter the bootloader. Solid red led either button pushed or not.
