U-Boot for the TQ-Systems TQMa7x modules
########################################
This file contains information for the port of
U-Boot to the TQ-Systems TQMa7x modules.
***********
Boot source
***********
The following boot sources are supported:
- SD/eMMC
- USB (SDP)
QSPI boot is functional but requires an additional prepended NXP header
image. This currently unsupported in u-boot.
********
Building
********
To build U-Boot for the TQ-Systems TQMa7x modules:
.. code-block:: bash
make tqma7_mba7_<boot>_defconfig
make
**boot** is a placeholder for the boot device:
+------+-----------+
| mmc | SD/eMMC |
+------+-----------+
| uuu | USB (SDP) |
+------+-----------+
The default build artifact is named ``u-boot-with-spl.imx``.
*****************************************
Serial Download Protocol (SDP) / USB boot
*****************************************
The complete system image can be programmed with ``uuu``
(https://github.com/nxp-imx/mfgtools) to eMMC.
Serial Download Protocol is supported on the Micro-B USB port (X5) of MBa7x.
The command ``fastboot usb 0`` is used to enable the fastboot gadget.
Build SDP enabled U-Boot image
==============================
.. code-block:: bash
make <som>_mba7_uuu_defconfig
make
Booting
