We have a customer using our product based on AGX Orin 64G module.
when the power mode was set to MAXN, ran his program.
He observed ‘Throttling due to over-current’.
I found that the OC3 event cnt kept increasing and the cause is curr4_crit has been trigged.
current setting comes from device tree, it’s 5520ma.
if i inreasse this by
sudo echo 8000> /sys/bus/i2c/drivers/ina3221/1-0040/hwmon/hwmon4/curr4_crit
no new throttling event notify.
What’s the risk if i increase the the value of curr4_crit?
this reflects the current of DDR.
but it’s fixed for all power modes.
Hi dennis.hu,
Are you using the custom carrier board with AGX Orin 64G module?
What’s the Jetpack version in use?
OC feature is created to protect the module.
We don’t suggest modifying the threshold to prevent the damage to the module.
Please create the custom power mode configuration according to your use case instead.
We’re using custom carrier board with AGX Orin 64G SOM.
We’re using Jetson Pack 6.0.
Okay, please prevent using MAXN as it is an unconstraint power mode rather than best performance mode.
The OC event will be triggered as expected if it exceeds the threshold.
