In-order to use a non-chargeable battery for the RTC backup Coin cell on the Jetson Nano dev-kit, it is mentioned in the user guide to disable the battery charging circuit. Could someone please elaborate on how to disable the real time clock backup coin cell before it is installed?
Hi,
You need to configure the BBCEN bit in the CNFGBBC register of pmic. This could be done with the help of device tree and driver code/readme file.
Driver code: kernel/kernel-4.9/drivers/mfd/max77620.c
readme: kernel-4.9/Documentation/devicetree/bindings/mfd/max77620.txt
How do I configure the registers on the PMIC of Jetson Nano Devkit B-01?
This could be done with the help of device tree and driver code/readme file.
Driver code: kernel/kernel-4.9/drivers/mfd/max77620.c
readme: kernel-4.9/Documentation/devicetree/bindings/mfd/max77620.txt
Do you have experience of configuring device tree?
No. Could you please suggest some videos/tutorials to follow that would help me?
Thanks in advance. Regards.
Please download the kernel source code from this link and follow the developer guide to rebuild the dtb files.
