My FRDM-KE02Z has the led always blink "2 seconds off followed by 8 rapid on/off blinks" and it 's always in bootloader mode.
I cant go to debug mode.
I try to upgrade bootloader as The Freescale OpenSDA Trap: “No Device Available”, or something like that…. | MCU on Eclipse but it still has the problem below.
What should I do
Are you using a Windows 7 machine for updating the bootloader?
You need a Windows 7 machine for this.
For the error codes and recovery, see Bricking and Recovering OpenSDA Boards in Windows 8 and 10 | MCU on Eclipse
I hope this helps,
