in the thread that you sent, the problem is indicated that spi pins are configured to work with regular gpio, but I want to use spi0, in device three I can see the âstatus okayâ, this is the default firmware, in the jetson-io.py configuration these pins are also assigned using spi
Tell me, is it really not possible to use spi normally in the most basic version of the firmware?
SPI is not enabled by default so that I wrote the steps to enable it.
These modifications is to remove the SPI pins configured as GPIO.
You should download the kernel source and find the dts you are using which includes these configurations.
Or you could just refer to 2-2-2. Method 2 - Remove from decompiled dtb to do this.
Do I understand correctly that the 2-2-2 method requires re-building the system?
Hi @KevinFFF would you be able to help with the above question?
Hi
Probably your silence is a sign that the system still needs to be rebuilt.
I installed the toolchain and everything necessary, then I deleted these pins from the required file
- TEGRA_GPIO(C, 0)
- TEGRA_GPIO(C, 1)
- TEGRA_GPIO(C, 2)
- TEGRA_GPIO(C, 3)
- TEGRA_GPIO(C, 4)
After that I built the device tree:
make ARCH=arm64 O=$TEGRA_KERNEL_OUT -j8 --output-sync=target dtbs
And completed the image build:
make ARCH=arm64 O=$TEGRA_KERNEL_OUT -j8 --output-sync=target zImage
Now I enter this command for flash and get this:
sudo ./flash.sh jetson-nano-qspi-sd mmcblk0p1
droid@droid:~/Documents/Lin/Linux_for_Tegra$ sudo ./flash.sh jetson-nano-qspi-sd mmcblk0p1

Perhaps I made some mistake in the process or missed some step?
No, the Method 2 doesnât require you to rebuild the kernel image.
Please just refer the steps to decompile the dtb and assemble it back.
Is there any file under Linux_for_Tegra_rootfs/?
so I still have to reflash my board, Iâm asking about a method that makes changes to an already flashed board
No, you donât need to reflash the board with Method 2.
You just need to extract the dtb under /boot/dtb/kernel_XXXX.dtb and modify it.
It seems you didnât extract the sample rootfs in Linux_for_Tegra/rootfs/.
how can I extract the sample rootfs, what is needed for this?
Please refer to the following instruction to setup BSP package.
NVIDIA Jetson Linux Developer Guide : Quick Start | NVIDIA Docs
But you donât need to do that if you are trying the Method 2 to modify device tree.
Hi @KevinFFF
I followed the instructions, downloaded rootfs from this site (https://developer.nvidia.com/embedded/linux-tegra-r3272) and build a new image
After that, I used the command (sudo ./flash.sh jetson-nano-qspi-sd mmcblk0p1) and flashed the module, but there is a nuance
The Ubuntu on the device is standard, itâs not JetPack, itâs just regular Ubuntu 18 without any nvidia tools
here is the sequence of steps I followed:
wget https://developer.nvidia.com/embedded/l4t/r32_release_v7.2/t210/jetson-210_linux_r32.7.2_aarch64.tbz2
wget https://developer.nvidia.com/embedded/dlc/l4t-gcc-7-3-1-toolchain-64-bit
wget https://developer.nvidia.com/downloads/embedded/l4t/r32_release_v7.4/t210/tegra_linux_sample-root-filesystem_r32.7.4_aarch64.tbz2
tar -xf gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz
tar -xf Jetson-210_Linux_R32.7.2_aarch64.tbz2
cd Linux_for_Tegra/
./sorce_sync.sh ( then enter tegra-l4t-r32.7.4 - kernel version 4.9-337 )
cd ..
tar -jxpf tegra_linux_sample-root-filesystem_r32.7.2_aarch64.tbz2 -C Linux_for_Tegra/rootfs/
export TEGRA_KERNEL_OUT=$PWD/kbuild
export CROSS_COMPILE=$PWD/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
export LOCALVERSION=-tegra
cd Linux_for_Tegra/sources/kernel/kernel-4.9/
mkdir -p $TEGRA_KERNEL_OUT
make ARCH=arm64 O=$TEGRA_KERNEL_OUT tegra_defconfig
make ARCH=arm64 O=$TEGRA_KERNEL_OUT -j8 --output-sync=target dtbs
make ARCH=arm64 O=$TEGRA_KERNEL_OUT -j8 --output-sync=target zImage
cd $TEGRA_KERNEL_OUT
cp /arch/arm64/boot/Image ../Linux_for_Tegra/rootfs/boot/
cp /arch/arm64/boot/*tegra* ../Linux_for_Tegra/rootfs/boot/
cd ../Linux_for_Tegra
sudo ./flash.sh jetson-nano-qspi-sd mmcblk0p1
You may need to install SDK component with the following command on your board.
$ sudo apt install nvidia-jetpack
canât find package nvidia-jetpack

How did you flash your board?
Could you share the result of the following command on your board?
$ cat /etc/nv_tegra_release
$ cat /etc/nv_boot_control.conf
But it seems another issue and not relate to current SPI issueâŠ
Hello
I found a mistake
I missed applying the apply_binaries.sh script
after that I flashed my module and now there are nvidia components.
But I also continue to follow the Spi instructions
and I donât get anything on spi pins
