Hi,
... VDD_GPU_SOC 22453mW/14932mW ...
... VDD_GPU_SOC 22854mW/16517mW ...
... VDD_GPU_SOC 23246mW/17638mW ...
Based on the output, the device does over the current limit in “VDD_GPU_SOC”.
So system throttling is expected.
To avoid this issue, you can try to add a custom power mode. (ex. lower the CPU clock)
Edit /etc/nvpmodel.conf
…
< POWER_MODEL ID=5 NAME=Custom >
…
CPU_A78_0 MAX_FREQ 1190400
…
$ sudo nvpmodel -m 5
Reflashing is required to downgrade the JetPack version.
Thanks.
