When running usdpaa lpm-ipfwd application in a demo board with the T1040d4rdb SoC and send traffic for about some hours,I got the following errors reported by the EDAC:

Is there someone that could explain what could be the next steps in my investigation?

thank you.

Your T1040 memory controller detects single-bit memory corruption.
Single-bit memory errors are correctable, but they should not happen
in a healthy system. These errors happen either because the memory
controller is improperly initialized or because of  a hardware problem
with memory. Possible actions are:

1. Reflash your board with NXP SDK pre-built images valid for your board.

2. Undo board modifications, if you have done  any.

3. Replace memory.

4. Replace power supply.

5. Replace the board.

Details about T1040 DDR error detection can be found in
T1040RM, Section 14.5.8.


Hope this helps,
Platon
