Hi, Please share the log attached to this E2E thread (not by email; BTW, I did not receive any; our server may have blocked it). 

Also, please provide details on our earlier question - Can you give us more information about what software/SDK you are running and what user guide you looked at?

Thanks.

Hi Praveen

I remail again.

Software do not change; I utilize the original SD card when we got the j721e and the card can run at room temperature smoothly.

For the project requested. I put the board into chamber with 85C.

And I tested 2 boards that we bought this time. The Attached are their log.

I enter root.

And I keyin memtester 900M 999. And it can run initial.

Then the board reboot. It is not the end of memtester.

Notice me, if it has any unclear.

Thanks

Hi Sam,

I notice that your log is labeled "HT." It seems that you start a memtester run and then stop that process and re-start a second memtester run which fails.

1. could you try room temperature?
2. Obviously, you are running memtester on 900MBytes of memory and trying to run 999 loops. If you ran 1MByte for 1 iteration at Ta = 85C, does it work?
3. what is the difference between SD27 and SD28? Different iterations of the same board/software or variations in hardware or software?

Sam,

In case there was any reset due to thermal shutdown, you can read the below register after the reboot:

Unlocking as per request.

Please share the register dump requested above and test results requested by Kyle.
