K70 processor reset pin always low

felicita — Fri, 17 Jul 2015 11:56:37 GMT

Hi all,

The reset pin is always low in our custom K70 board. We have pulled the reset pin up externally using 10k resistor. EzPort pin is also pulled high through 10k resistor. We aren't able to trace why this persists.

Your inputs would help us a lot!

Thank You!

Regards,

Felicita.

Hello Felicita,

Could you please share with us the debug/programming interface section of your schematic?

Best regards,

Earl.

Hi Felicita,

Did you figure out what is happening ? We have the same problem with a custom board with an MKW24.

Thanks

Pramod
