Hello Steven,
Could you please explain a little bit more the issue???
Could you please check the below jumpers settings???
Which MQX version are you using???
For standalone operation:
o TWR-K60D100M - Jumper J10 on position 1-2
For using USB Host mode, jumpers on position:
o TWR-SER board - J16 on position 1-2 (VB_HOST)
o TWR-SER board - J10 on default position 1-2 (USB host)
For using USB Device mode, jumpers on position:
o TWR-SER board - J16 on position 3-4 (VB_DEV)
o TWR-SER board - J10 on position 2-3 (USB device)
To enable Ethernet communication (use with TWR-SER):
o TWR-K60D100M - Jumper J10 on position 2-3 - processor clock taken from the TWR-SER board
o TWR-SER - CLK_SEL 3-4
o TWR-SER - CLKIN-SEL 2-3 (processor clock is taken from PHY)
o TWR-SER - ETH-CONFIG J12 9-10 to select RMII communication mode
Important: Plug both the processor and the serial board (TWR-SER) into the Tower. The processor is using the external clock from the Ethernet PHY on the serial card.
Have a great day,
Sol
