Choose the 'HelloWorld.hex' file which is in 'mbed-ce-hello-world/mbed-os/'. To upload the hex file to the T40 open the Teensy UI and click on 'File'. built: /home/wwatson/mbed/mbed-ce-hello-world/mbed-os/HelloWorld.hexġ8.
Output should be something like:Ĭode: - built: /home/wwatson/mbed/mbed-ce-hello-world/mbed-os/HelloWorld.bin GNinja -DCMAKE_BUILD_TYPE=Develop -DMBED_TARGET=TEENSY_40'.
You should now be in 'mbed-ce-hello-world/mbed-os/'. Then do: 'git checkout dev/fix-teensy4-issues'.ġ7. First change to the mbed-os directory: 'cd mbed-ce-hello-world/mbed-os/'. This next step switches to mbed-os branch we are using for testing with the Teensy T40. Then execute the following: 'git clone -recursive ' Make sure to use the '-recursive' option as this will bring in the needed mbed-os submodule.ġ6. First cd to the directory you created in step 1. Now to get Mbed CE Hello World project from GitHub for testing.

Next install a few python dependency's: 'sudo apt-get install python3-pip python3-setuptools python3-wheel'ġ5. You should see: '/usr/local/gcc-arm/bin.' at the begining fo the print out.ġ4. Reset the PATH variable with 'source ~/.bashrc' then check to make sure it's set with: 'echo $PATH'. Add this to the end of the open file: 'export PATH=/usr/local/gcc-arm/bin:$PATH'. Basically, we are adding the path to '/usr/local/gcc-arm' to the existing PATH enviroment variable. With a text editor open (in my case) '.bash' or '.profile'. Next 'cd ~/' to get to your home directory.ġ2. Move and rename the resulting directory to /usr/local directory: 'sudo mv arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi /usr/local/gcc-arm'ġ1.
Extract the package with: 'tar xf arm-gnu-toolchain-12.2.rel1-x86_' This may take a little time on a slow computer.ġ0. Again, dropdown to this section: 'x86_64 Linux hosted cross toolchains' 'AArch32 bare-metal target (arm-none-eabi)'Ĩ. Install other needed packages: 'sudo apt-get install libncurses5 libncursesw5'.ħ. Install Ninga Build: 'sudo apt-get install ninja-build'ĥ. Skip over step '1.' and start at step '2.'.Ĥ. MBED CE OS installation instructions for Ubuntu 22.04 with Teensy T40.ġ.
