MFGTool DEBIAN-STRETCH
======================

This guide describes how to flash a Debian Stretch Root Filesystem with MFGTool.

1. Go to our `Download Area <https://www.karo-electronics.com/downloads>`_ and download the MfgTool-2018-08.zip (if you don't have it already).
2. Also download Mfgtools-TX6-2018-08-DEBIAN-STRETCH.zip.
3. Unpack the custom folder.

*Mfgtools-TX6-2018-08-DEBIAN-STRETCH* contains a custom folder which can be copied onto an existing Mfgtools-TX6-2018-08 installation.

4. Start **MfgToolSetup**

.. note:: Use *MfgToolSetup* to set up with the options listed below. General instructions how to set up MFGTool are shown at :ref:`mfg-tool-setup`.

Environment
------------

Choose ``debian.env``. This file includes the required environment settings:

.. code-block:: text

   append_bootargs=rootfstype=ext4
   bootcmd_mmc=setenv autostart no;run bootargs_mmc;ext2load mmc 0 ${kerneladdr} vmlinuz
   bootz_cmd=bootz ${kerneladdr} - ${fdtaddr}
   bootcmd=run bootcmd_${boot_mode} bootz_cmd
   default_bootargs=setenv bootargs console=ttymxc0,115200 rw quiet panic=1 ${append_bootargs}

* Debian uses ext4 for the rootfs and needs it to be writeable.
* ``${kerneladdr}`` is automatically added by MfgTool 8MiB below ``${loadaddr}``
* bootz is used instead of bootm

DTB
---

Choose a dtb which matches your module and baseboard:
