Jetson Nano B01 (2 camera ports) info

Hello,

I need information about the new Jetson Nano B01 with 2 camera ports.
A quick search in the net did not help.

  1. Can I use L4T 32.2 or I should use newer kernel version (which)?
  2. Pins for serial cable, using serial console ?
  3. How to enter force recovery mode?
  4. Camera driver examples (device tree, I2C addresses) for the 2 ports.

Greetings,
Plamen

I found answers of questions 2. and 3. in NV_Jetson_Nano_Developer_Kit_User_Guide.pdf, chapter “Interface Details”

  1. It’s better to use the latest version. Current version is r32.3.1
  2. Have a check l4t docuemnt.
    https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fcamera_dev.html%23

Thank you.

How about flashing Nano B01 ?
Is it compatible with the production module P3448-0020 ?

B01 DTB file:
tegra210-p3448-0002-p3449-0000-b00.dtb
Flash B01:
sudo ./flash.sh -r jetson-nano-emmc mmcblk0p1
Flash B01 dtb only:
sudo ./flash.sh -r -k DTB jetson-nano-emmc mmcblk0p1

Is that right ?

Yes, and you should need the MISC patch for updating the DTB only for Nano(sdcard image).

https://elinux.org/L4T_Jetson/r32.3.x_patch

Sorry, but the following link is nonexistent:

The like are alive again. Have a try again.

I failed to install L4T 32.3.1 on Jetson Nano Devkit, following the instructions from:
How to build NVIDIA Jetson Nano kernel - RidgeRun Developer Connection
All build steps finished OK except the last step:
export CROSS_COMPILE_AARCH64_PATH=$HOME/l4t-gcc/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu
./nvbuild.sh -o $TEGRA_KERNEL_OUT
because nvbuild exits with error message: missing configuration.
Could not find information about nvbuild and why this step is needed.

And have a check the l4t document to build the kernel.

https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fkernel_custom.html%23

When started to reboot, the Nano board falls in infinite loop.
At the end of the system log from line 579 and above, there are unpleasant messages (i don’t know if they are normal) like:

Card did not respond to voltage select!

USB0:   tegrausb: Invalid dr_mode 2 for host mode

I’ve checked this section of the document and did not found something different from my kernel compilation. There is no information about nvbuild.sh, which failed in my case.

Did you used customization kernel Image?
Did you export LOCALVERSION=-tegra before build the image?
