WCT-15W1CFFPD not working

We recently acquired a WCT-15W1CFFPD evaluation kit that uses a MWCT1013 chip but it's not working.

When we power up the board the red and green LEDs turn on for less than five seconds and then the green LED turns off and the red LED starts blinking and stays that way. We then tried to place a Qi-enabled phone on the coil but nothing happens. The charger is not detected at all. It's an iPhone 8 that works fine with other Qi chargers.

Also we tried to connect the board to FreeMASTER using a USB-UART board but we get an error: "Can not detect the board information ! The communication will be paused. Error code 0x80000101 (Response timeout.)" Using the wizard to probe the UART fails to detect the board too.

 

What could be the problem?

Hi Jose,

Yes, this issue is happening right out of the box. I was wondering if we have to program the chip when using it for the first time or does it come with firmware programmed by default?

David

Hi,

The board should come with firmware programmed by default and should work out-of-the-box.

Hi,

 

WCT-15W1CFFPD seems to be entered in an unknown stage, as you can see in the LED indication section (section 9.2) of the device user guide (https://www.nxp.com/docs/en/user-guide/WCT101XV10AUG.pdf), there are no pattern for GREEN LED OFF and RED LED BLINK.

 

If this issue you have is an out-of-the-box issue, I recommend you to contact your board distributor for a replacement.

 

Regards,

Jose

Hi Jose,

Thank you for your help! We have contacted our distributor and we are waiting for a replacement. However, since it is backordered, it could take a while to get our replacement board. In the meantime, is there anything we could do to make this board work?

Regards,

David

Hi David,

 

Yes, you can try to reprogram the board, to do this please follow steps mentioned on section 7 of the user manual: https://www.nxp.com/docs/en/user-guide/WCT101XV10AUG.pdf
