I want to disable the RTC battery charger function, but i can only find examples on how to do this with the kernel builder. I already have the device up and running fine but now i need to disable the battery charger function.
Is there a way to disable the battery charger without having to rebuild the kernel/re-flash the device?
This is my first time using NVIDIA Jetson devices so perhaps i am missing something very basic.
Any help is appreciated
Hi , we still need support, we are running A Jetson Xavier NX module and want to disable the RTC backup battery charger. WE made the image on a virtual machine (Ubuntu 18.04 64bit).
Hoping you can help,
We are having some trouble disabling the battery charger. after adding your advised change it seems to be still enabled. below are the steps we have taken to try to disable the battery charger along with additional information about our setup:
setup:
Xavier NX module with custom carrier board (based around the “P3509-A01 Jetson Xavier NX Carrier Board”)
Host system for configuration and image building: Linux Ubuntu 18.04.
Image building/ adaptation steps:
Get base image files with the NVidia SDKManager tooling.
Run installer until image is ready and it asks to flash target >> skip flashing.
close installer
Make changes in resulting image files, located: /nvidia/nvidia_sdk/JetPack_5.1_Linux_JETSON_XAVIER_NX_TARGETS/Linux_for_Tegra/bootloader/t186ref/BCT/
run ./flash.sh “jetson-xavier-nx-devkit-emmc” “mmcblk0p1”
Image buiding and flashimg of the module seem to go correctly according to terminal ouptut.
Restart module after flashing >> still measuring 3V on the battery connection.
we also tried these steps but with the target file being (same configuration change):
“tegra194-mb1-bct-pmic-p3668-0001-a00.cfg”
location: Linux_for_Tegra/bootloader/t186ref/BCT/tegra194-mb1-bct-pmic-p3668-0001-a00.cfg
Are we correctly rebuilding the image using the “./apply_binaries.sh” command or do we need to take other actions to rebuild.
