s32k148 evb powered by micro-USB blinking green

[naderkhamess]

Hello, I am trying to operate S32K148 EVB using micro-usb, it is working so far. However, sometimes when I unplug the USB from power and plug it again, I see the LED beside the micro-usb is blinking green/yellow always and MCU is not responding. 

I get this error when try to communicate via debugger : Communication error while accessing MDM-AP

what could be the reasons? 

 by the way, when i try to replug it again, it is working and other LEDs in the board are on again. but i am curious what could be the reason to avoid it.

thanks!

Hello Robin, I am facing the issue with S32K148 EVB during flashing. When I start to flash the board green LED starts to blink rapidly. It follows the same pattern as mentioned in the image corresponding to the error state description.

Hi 

Would you please let me know which LED is blinking green, do you mean D10?

D10 is OpenSDA LED, if D10 is blinking green, then please check the "Table 2. LED Status and Mode Information":

Best Regards,
Robin
