Hi,
After playing with FRDM platform,I just started my own PCB.This this the schematic for it, But I do not know why the reset pin keeps toggling!? Please see the picture,
So do you have any Idea what's going on wrong?
Hi Ali Asadzadeh,
To a new out of factory kinetis chip, reset pin keeps on reseting is the correct wave, after you download a code to the kinetis flash, the reset will not reseting.
Please download a code to your chip at first, then you can check it again.
Wish it helps you!
Have a great day,
Jingjing

Hi Ali Asadzadeh,
The new chip's reset signal won't influence the JLINK detect, please use the JLINK commander, whether it can find the ARM cortext M0+ core? If it can't find the core, you need to check your hardware, whether your JLINK signal to the chip is correct?
Besides, now, how many board meet this problem?
Best regards,
Jingjing
