I am current diagnosing Jetson Orin NX. I come across with the following parameters which do not have labels when I acquire them. Could anyone here help please.
The parameters are:
Current:
curr1_input
curr2_input
curr3_input
curr4_input
Voltage:
in4_input
in5_input
in6_input
Temperature:
There are nine temperatures represent 9 different thermazl_ones, but I don’t know what these zones are and what device’s temperature they are representing. Where in the datasheet would I be able to find out?
Please refer to the link I shared and let me know if you have further questions.
There should be 3 channels for specific current, and the channel 4 is the summation of channel 1 to 3.
You could just ignore the voltage input 4 to 6.
As I see from the link you shared, curr4_input is the summation of curr1_input to curr3_input, but the numbers do not add up, most of the time curr4_input is lower the summation of the 3, but sometimes curr4_input spikes to a certain value that exceeds the summation of the 3 current inputs. Curr4_input fluctuates a lot, could you advise please.
Also, what is the dynamic hwmon indices in the path below?
What is the range of , and what does each hwmon represent?
/sys/bus/i2c/drivers/ina3221/1-0040/hwmon/hwmon (Where is dynamic hwmon indexes)
As we can see “For equals to 4, it represents the summation of the channel”. I believe refers to curr_input which is the current, correct? But your reply states that its summation of voltage. I am confused here.
Speaking of voltage, in7_input has a label of summation of the shunt voltage, could you confirm that the reading from /sys/bus/i2c/drivers/ina3221/1-0040/hwmon/hwmon/in7_input is in milliwatt rather than millivolt, since what we measured from in7_input is way higher than our in1_input (VDD_IN) which does not make sense.
Okay, so voltage and current have the same mapping of <j>, is it correct? But the data we acquire from the Orin still don’t make sense, Channel 4 value is not the sum of Channel 1 (VDD_IN) and Channel 2 (VDD_CPU_GPU_CV).
Also, looking back to your replies, shown below, you said Voltage input_4 can be ignored, but now you said voltage 4 is the sum of VDD_IN and VDD_CPU_GPU_CV, but it does not match my data. Could you clarify more on these voltage and current parameters please.
I will provide two sets of values of curr1_input, curr2_input and curr4_input where there are no spikes and there are spikes in curr4_input.
Set 1 (No spikes in curr4_input):
curr1_input: 3304
curr2_input: 1936
curr4_input: 4992
Set 2: (Spikes in curr4_input)
curr1_input: 3200
curr2_input: 1880
curr4_input: 10312
I am trying to understand why there are spikes in curr4_input, would this spikes in curr4_input affect other components in the I2C, which in turn causes packet loss, which I am experiencing at the moment, while transmitting data across ethernet cable.
