hi ,
Im working on the orin nx board , use r35.6.2 version .
Pad Voltage DT Binding — NVIDIA Jetson Linux Developer Guide 1 documentation
when i read this doc, but the hardware/nvidia/platform/t23x//bct/ not exist .
I have download all sdk source , but bct directory nost exist in “Linux_for_Tegra/source/public/hardware/nvidia/platform/t23x”.
anything wrong? and how to get this files ?
Please check the files in your BSP directory Linux_for_Tegra/bootloader
find in bootloader
Linux_for_Tegra/bootloader$ find . -name BCT
./t186ref/BCT
so, how do I know which one is use ? thanks. any config file?
The method that you flashed the board would decide which file is in use.
For example, if you use board config xxx.conf to flash, then you should read xxx.conf and it will tell which file is in use.
sorry , can you give me more info.
I use this script to burn board.
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 \
-c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
--showlogs --network usb0 --erase-all jetson-orin-nano-devkit internal
I have checked the xml file , no *.conf file found, so can you tell me , which config default use ？
No, not related to the xml. That thing does not matter.
“jetson-orin-nano-devkit” in your flash command is not magic word.
It just means you are using “jetson-orin-nano-devkit.conf” in Linux_for_Tegra.
That is what we call board config and what you should look into.
thanks， have a nice day
hi ,
another thing, this conf file is shell script , right? or any other doc to help me read?
That is not a shell script. Just a list of config that our flash tool would help parse it.
What is the exact thing you want to know here? If you just want to know specific file, then grep its name should be sufficient.
our company designed a carried board . I need build custom system .
here’s some work I need do .
- change pinmux
- change device tree
- some secure things
I have build kernel , device tree… but there are so many device tree dtb file have generated, which one should i use ? the defualt kernel_tegra234-p3767-0000-p3768-0000-a0.dtb is not exsit from my build . I have use grep and find command .
If the board config is too complicated to read then you could directly check the flash log printed on host.
thansk , i will try
