Hi everyone,
I am using MT62F2G32D4DS-023 IT:C chip in my project. I run "memtester-arm 20 > /dev/null &" command and got the following errors

Can someone explain why I got this error?

 

[helpstar]

try memtestx86

 

[antony67543]

try memtestx86

Can you explain why I gont this error? How to solve this error? Is that software concern or hadware concern?

 

[helpstar]

don't know this tool nir can i interpret what's wrong, sorry.
can you try the other tool I posted?

 

[gamerk316]

Yeah, memtest86 is the gold standard for memory testing.

It looks like all the tool is doing is getting memory diagnostics within Linux, which is of very little use. Don't see anything obviously wrong, but you'd need to give the log to someone who understands the tool to confirm that.

Hi
Thanks for the reply
I am a hardware engineer
I am completely new this and now only I started to learn about firmware
Can you please explain what will happen if I run the "memtester-arm 20 > /dev/null &" command in the terminal?
