Failed building Nano u-boot

We failed to build Nano u-boot and got error “Can’t find default configuration “arch/…/configs/p3450-0000_defconfig”!”

Here is the steps I did, is there any I missed?

/Linux_for_Tegra$ ./source_sync.sh -u tegra-l4t-r32.2.1
/Linux_for_Tegra/sources/u-boot$ export CROSS_COMPILE=~/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
/Linux_for_Tegra/sources/u-boot$ make distclean
/Linux_for_Tegra/sources/u-boot$ make O=build/p3450-0000 p3450-0000_defconfig

error message:

Thank you for any advice,

It should be “p3450-porg_defconfig”. May I know where do you get this “p3450-0000_defconfig”?

Hi WayneWWW,

Thank you for your prompt support.
Yes. “p3450-porg_defconfig” works.

"p3450-0000_defconfig is from placeholders of U-Boot Customization of NVIDIA Tegra Linux Driver Package.

Placeholders in Commands
This topic describes many commands that use these placeholders:
• identifies the Jetson device in use. Substitute:
•For Jetson Nano: p3450-0000.
•For Jetson TX2 and Jetson TX2i: p2771-0000.
•<board_and_rev> identifies the Jetson device and revision in use. Substitute:
•For Jetson Nano: p3450-0000.

Thank you,

Thanks. We will update this document error.
