Part Number: DRA821U
Other Parts Discussed in Thread: DRA821, AM62P

Tool/software:

Tested on SDK10.0, DRA821 rt-linux latency is similar as that on AM62P, is it expected?

tress-ng -c2 --cpu-method=all &

cyclictest -m -Sp98 -i1000 -h400 -l100000000 -q

tress-ng -c4 --cpu-method=all &

cyclictest -m -Sp98 -i1000 -h400 -l100000000 -q

Hi Tony,

We do not perform the cyclictest.

Looking at the existing FAQs the AM62 is more or less what you are seeing.

I tried on DRA821 and the numbers are similar to what you have seen.
