lx2160a rdb boot continuous prints

[ganeshreddy-b38]

But today I am seeing the continuous prints on LX2160ARDB console which was left on that day idle.  Any idea of how to avoid using these EDAC error checking etc ?

What is causing these prints and how to fix it ?

Although changed DDR modules , started coming after a day.

Removed and re-inserted properly and programmed the new image into FlexSPI DEV#1 and changed 1 pin in 1 switch (similar to another working board in the LAB of another engineer)

So far it is good.  After onwards, it is booting directly from FlexSPI DEV#1 after we issue reboot from Linux.  So, it seems to me that DEV#1 partition is made to boot after power on.

Previously FlexSPI DEV#0 was present, and it was updated few weeks ago. May be not sure, whether FlexSPI DEV#0 has any issue or something else random behaviour.

For now, it Is good. Will monitor further.

But after 100 minutes later, it seems issue surfaced again, PFA attached logs of them,  share your points, if anything to fix.

Hello after power off and power on again,  it is working. LOoks like  ECC errors coming after some duration of power on.
