We want to incress GPU voltage on TX2. Is it possible?
Our VDD_IN is 12V.
Hi,
What is the purpose of doing this? We don’t support it.
Our application use GPU almost to 99%, sometimes TX2 hang up or just reboot directly.
So we doubt may be GPU power is not enough or stable.
The follow is one of system hang up boot up log. This happened our GPU&CPU stress test for long-term, then system reboot and hang up．

Hi,
For such issue, my suggestion is please find a TX2 devikt and use the adapters from TX2 devkit to do the stress test.
If you could hit this issue even on devkit, then please share us
- How to reproduce your problem? Which application are you using for stress test?
- Is there any error log from serial console before error happens?
Also, how to you get your device work again after you see such hang in reboot? Use coldboot?
- We use stress-ng to do cpu stess testing and use matrixMul.dat to do GPU stress testing.
- Unfortunately there is no error message output from serial console before reboot.
Yes use coldboot will fix this problem.
Anther wired issue is, since cpu hang up during reboot, but the power consumption is still up to 10W. Seems even cpu is dead but GPU stress test still work now.
We notice below info.
For abnormal reboot, the PMIC info is
[0009.567] I> pmic: reset reason (nverc) : 0x0
For normal reboot ,the PMIC info is
[0009.552] I> pmic: reset reason (nverc) : 0x44
What does the PMIC different info mean?
Hi,
Are you using devkit to do this test or not?
Sorry, we didn’t use devkit to do similar test yet.
We need to do internal discuss before start this testing on devkit.
Do you have any suggestion to locate this issue so far?
Hi,
Could you go to below node in the next reboot and dump the pmic reset reason?
/proc/device-tree/chosen/reset/pmic-reset-reason# xxd reason
You mean when problem show next time?
But our reboot will be hang up, and need to cold reboot again.
For that /proc/device-tree/chosen/reset/pmic-reset-reason still meaningful for our case?
Not sure. You could try it first.
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 bdehj,
Have you clarified the cause and resolved the problem?
Any result can be shared?
do you mean the matricMul samples in cuda samples?
can you tell the details about how to do the gpu stress test, thanks a lot.
