I am using MQX 4.2 on a Tower board K70F120M. I see that 1 out of 10 ping requests sent to the tower board are getting timed out on consistent basis. Has anyone seen this behavior?
Solved! Go to Solution.
Hi Ravindra,
When I have had Ethernet issues with MQX and Tower kits it usually has been a jumper setting issue.
Please review following document:
C:\Freescale\Freescale_MQX_4_2\doc\MQX_Getting_Started.pdf
Page 50 has the TWR-K70+TWR-SER jumper configuration MQX expects.
The K70 uses the Ethernet clock source from the TWR-SER card to clock both K70 and Ethernet PHY. This synchronizes the two clock domains. If they are not synchronized Ethernet issues arise.
Regards,
David

That helped. I no more see the ping timeouts after fixing the J18 settings.
Thank you very much. :smileyhappy:
