U-Boot for the TQ-Systems TQMa6x modules
########################################
The following hardware revisions are supported:
Modules:
+------------+----------+
| TQMa6ULx | REV.030x |
+------------+----------+
| TQMa6ULLx | REV.030x |
+------------+----------+
| TQMa6ULxL | REV.030x |
+------------+----------+
| TQMa6ULLxL | REV.030x |
+------------+----------+
Mainboards:
+----------+----------+
| MBa6ULx | REV.020x |
+----------+----------+
Hardware on modules TQMa6ULx, TQMa6ULxL, TQMa6ULLx and TQMa6ULLxL
- eMMC
- RTC
- PMIC
- SPI-NOR (optional)
- EEPROM
- Temperature sensor
- RAM (256 MiB / 512 MiB)
Supported hardware on Starterkit MBa6ULx:
- 2 Ethernet PHY connected to FEC0 / FEC1 (usage depends on CPU)
- SD-card slot
- UART
- USB
Note: To change the Ethernet port to use for networking functionality, use the
U-Boot generic environment variable ``ethact``.
.. code-block:: bash
setenv ethact <FEC>
***********
Boot source
***********
- SD/eMMC
- USB/SDP (with NXP UUU tool)
- SPI NOR (functional but requires additional prepended NXP header.
Not supported in U-Boot.)
********
Building
********
To build U-Boot for the TQ-Systems TQMa6L modules:
.. code-block:: bash
make <som>_<baseboard>_<boot>_defconfig
make
