We do provide our U-Boot sources, but we do not recommend rebuilding a custom U-Boot binary as it can leave the system in an unbootable state.

If proceeding with building a custom U-Boot, use the "tsimx_v2016.03_4.1.15_2.0.0_ga" branch from our github repo: https://github.com/embeddedTS/u-boot-imx this can be executed with the following command: 

git clone https://github.com/embeddedTS/u-boot-imx.git -b tsimx_v2016.03_4.1.15_2.0.0_ga u-boot-ts4100

When compiling, we recommend using ONLY this cross-compiler, the use of any other compiler may cause issues or may leave the system in an unbootable state! Specifically, we have experienced RAM problems when using a more recent cross compiler to build this version of U-Boot. The tarball can be extracted with the following: 

mkdir /opt/toolchains/ts4100/
tar -xf tsimx6ul-glibc-gnueabihf-4.9.4.tar.xz -C /opt/toolchains/ts4100/

Once the tarball has been properly extracted set up the following variables and run the build script: 

export ARCH=arm
export CROSS_COMPILE=/path/to/folder/bin/arm-tsimx6ul-linux-gnueabihf-

After the environment variables have been set up as shown above the build is now ready to be executed: 

cd /path/to/u-boot-imx
./build-imx6ul.sh ts4100

This will output binaries for 1 GB and 512 MB RAM variants in "/u-boot-imx/out/" that can be written to the device using the steps in Update U-Boot.

Note: If the following error message is received: "error while loading shared libraries: libmpfr.so.4: cannot open shared object file:" create the following symbolic link in Debian: 
sudo ln -s /usr/lib/x86_64-linux-gnu/libmpfr.so.6 /usr/lib/x86_64-linux-gnu/libmpfr.so.4
