[SOLVED] JLink Orange blink

bharaths · Apr 27th 2016, 9:53pm

Hi All,

I was trying to flash software to one of the dev boards with Atmel SAM4E16C chip and then the orange LED started blinking on the JLink Pro continuously. I have checked on RESETS on the target side. How do I recover back the JLink Pro to normalcy (Blink GREEN ) ?

Thanks for your help

Hi,

there is no orange LED on the J-Link Pro.
If both the red and the green LED is lit, the results is orange-like.
You say that it blinks orange. Can you see which color (red or green) is blinking and which one is solid?

Best regards,
Niklas

Hi,

Both the green and the red seem to be solid resulting in a solid Orange color of the LED.

Thanks

Hi Bharath,

sorry, i forgot to ask which LED is lit.
Is it the middle one? Or one with an arrow (up or down) next to it?

Best regards,
Niklas

Hi Niklas,

Its the LED that has the UP arrow next to it.

Thanks

Hi Bharath,

Status indicator (arrow up to J-Link side):

GREEN constant => J-Link measures the target reference voltage on pin 1 (VTref >= 1.2V)
RED constant => Target drives nRESET (pin 15) LOW

Best regards,
Niklas
