Very high loop times for some program cycles in newly designed carrier board for Nvidia Jetson TX2

Hi,
I resently designed and created a new carrier board for Nvidia Jetson TX2 computer module. It worked well but there was a small problem that the loop time of the program I run in the Jetson TX2 shows very low performance from time to time. When I run the same program in the original development board, the looptime is nearly 3.0 milliseconds. But the loop time reaches to 4 secods when the program is run in the carrier board I designed. Can this be a design problem of my carrier board or is there any other reason?

This image shows the loop time vs, the program cycle count. It shows the loop time rises to 4 second for some program cycles.
Thank you!

can you share the tegrastats output in your board?
Also boot log?
Generally, since CVM is the same, there should not be any perf difference, if you are using the right power delivery and any of the new IOs you have using is not hogging cpu.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Hi chathushkarathnapala,

Is this still an issue to support?
Any result cane be shared?

Thanks
