Hi Nvidia,
SDK: Jetpack 7 R38.2 flashed onto a designed carrier board.
Execute the following commands:
sudo mvpmodel -m 0
sudo jetson_clocks
After running sudo tegrastats, the CPU frequency did not reach 2.6 GHz.
However, this issue was not observed on the Jetson AGX Thor devkit.
I would like to query Nvidia: If the INA238 chip is removed from the designed carrier board, will this allow the CPU, GPU, or EMC frequencies to reach their maximum?
Although attempting to increase the CPU frequency at the OS level, will it be restricted by the BPMP Firmware?
If the INA238 chip is replaced, which parts should be modified?
Besides modifying the following in source/hardware/nvidia/t264/nv-public/nv-platform/tegra264-p4071-0000.dtsi:
i2c@c600000 {
ina238@44 {
compatible = “ti,ina238”;
reg = <0x44>;
shunt-resistor = <2000>;
status = “okay”;
label = “VIN”;
};
};
No INA238-related information was found in bootloader or source/hardware/nvidia/t264/nv-public/. The only exception is the bootloader/rcmboot_blob/blob.bin file, but I believe this part is not provided by Nvidia for external modification.
Thanks.
