U-Boot build fails for Jetpack 3.2.1

Robotics & Edge Computing Jetson & Embedded Systems Jetson TX2
1

Hello,

I’m trying to rebuild the NVidia U-boot using Jetpack 3.2.1 SW and the L4t documentation for the Jetson TX2 board.

The host build system I use is running Ubuntu 18.04.4

I have downloaded the latest version of the Device Tree Compiler, since no precise version has been specified. The install location I used during the make install command is /usr/local.

Next I downloaded and installed the recommended Linaro 7.3.1. 2018.05 toolchain and I downloaded the u-boot sources using the source_sync.sh script.

I try to build U-Boot by executing the commands:

$ export CROSS_COMPILE=/opt/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
$ make distclean
$ make p2771-0000-500_defconfig
$ make

The build fails as can be seen in the next error snippet:

                 from tools/fdt_host.h:11,

././include/compiler.h:66:9: error: expected ')' before '&' token
  ((((x) & 0xff000000) >> 24) | \

From what I can tell, the u-boot sources and the device tree compiler have different version of the files
fdt.h , libfdt_env.h and libfdt.h.

What actions need to be taken to fix the U-Boot build?

3

What uboot release are you using? Does jetpack 3.2.1 mean re-28.x?

4

If this is rel-28.x, please use the old toolchain. Linaro 7.3.1. 2018.05 may only work for rel-32.x release.

5

I use the information from page U-Boot Customization, based on Release 32.3. According to the SDK Mannager, I am using JetPack 4.3, which uses L4T 32.3.1.

In the mean time I have found that when I install the Device Tree Compiler package, instead of downloading and compiling the tool myself, the 3 header files, fdt.h, libfdt_env.h and libfdt.h, are not part of the Ubuntu package.

When using the Device Tree Compiler from the Ubuntu package, I am able to build U-Boot albeit the build contains a fair amount of build warnings.

This might solve the build failing, but I am reluctant to use this u-boot since I am not sure it will work correctly given the build warnings:

Hi olaf.heemskerk,

When using the Device Tree Compiler from the Ubuntu package, I am able to build U-Boot albeit the build contains a fair amount of build warnings.

Which version of dtc tool you are using?
You could try to use the dtc here.
/Linux_for_tegra/kernel/dtc

9

I have now tried 3 different versions of the device tree compiler to build u-boot.

  1. Using the device tree compiler created from the sources, as mentioned in the documentation, which is DTC version 1.6.0, results in build-errors. If I delete the 3 before mentioned header files from the DTC installation precedure, the U-Boot build results in build warnings.
  2. Using the device tree compiler installed form the Ubuntu package, DTC version 1.4.5-3 also results in build warnings.
  3. Using the device tree compiler contained in the L4T package (/Linux_for_tegra/kernel/dtc), version 1.4.0, builds U-Boot without build warnings.

It therefore looks like I should use the DTC form the L4T package for the U-Boot build.

This leaves me with the question whether the DTC version in the L4T package is a standard release or if the sources have been modified to accommodate NVidia specific changes.

10

As en exercise, I downloaded the device tree compiler from DTC Git repository, with tag v1.4.0, which is the same version as ditributed in the L4T package.

Using this locally build 1.4.0 version of the device tree compiler, U-Boot can also be built without build errors and/or warnings.
