Failure Summary

OEDCS Control V1.1 board bring up. I initially gave this a title of Ethernet Connects For Some Time, Then Fails, Watchdog Timer Resetting DUT. But on reviewing the data I see that the Ethernet never connected during this test.

This device has previously connected to the internet and gotten correct UTC. On this test run it did not connect from the start.

Test setup

Testing with Due, OEDCS Control V1.1 SN 9 (With R95 removed) Ethernet card ??? Capture serial stream with Tera Term to file with time stamps.

Firmware: OEDCS; Rev: 0.3.10

Test Journal

The device was powered up. 2023-11-09 14:13:23.794] Starting OEDCS; Rev: 0.3.10

It operated

The device reported critical error for Ethernet connection at a later time.

This was a duration from boot till this critical error is of about four minuets.

The Watchdog timer appears to have been rebooting the system seven times during this period.

I reexamined my work on issue PubInv/NASA-MCOG#66 and confirmed that I had seen the device connect to the internet and get time. image

Now it is consistently NOT connecting to the internet.

ForrestErickson commented 10 months ago

I removed additional resistors R93, R94, and R96 and retested. The Ethernet connection works and for ten minuets now is stable.

ForrestErickson commented 10 months ago

The Ethernet connection has run for about 24 hours just fine.

I captured a log and found no occurrences of the Ethernet CRITICAL ERROR message. image

I will remove R93, R94, R95, and R96 from all boards.

Closing issue.
