Hi,
I've ran into a strange issue with eTSEC controller on P1020RDB. It seems like there's a fair amount of packet loss when I PING my target. PING with smaller payloads are okay but the problem becomes severe when I try to use a ping with 1024 bytes payload.
While troubleshooting the issue, It seems like the packets are being properly received by the controller but response packets are not transferred on the wire by eTSEC.
Here's some info about my environment.
I'll appreciate your comments.
Thanks!
Please see below technical support comment:
Based on this information it is not possible to figure out the root cause of the problem. PING is a user-level utility that accesses the network through the services provided by the IP stack, which is not implemented in Freescale hardware.
If you believe that the problem is related to eTSEC hardware, please provide a hardware level problem description, namely:
1. Actions taken by the software with respect to eTSEС (register or shared memory structure
updates) that immediately precede the problem manifestation and/or suspected to
cause the problem.
2. Observed response of the hardware (if any) to the actions specified in p. 1 and why
this response is considered incorrect.
3. Any explicit error indications returned by eTSEC in BDs and IEVENT.
