Third-Party Add-Ons

The TQMLS1028A debug UART is connected via a FTDI USB-to-Serial converter to X19 (micro-USB) on the MBLS1028A. A micro-USB/USB-A cable for the connection to the host PC is part of the STKLS1028A accessory set.
Depending on the host operating system, the USB-to-serial converter driver may need to be installed.

BSP Version History

Rev.0108

Update documentation

Rev.0107

BSP

TQMLS1028a build bl2 for all rcw variants
Added 800MHz RCW variants for sd boot and spi boot
Update machine configuration:
- Adjustments for latest meta-freescale for Layerscape based SOM preparation of better linux PREEMPT RT support

Rev.0106

BSP

new kernel linux-rt-lsdk-tq-5.10
perf: backport from Yocto Dunfell to fix build issues with newer kernels

Rev.0105

BSP

Use correct manufacturer EEPROM address

Rev.0104

BSP

Added new kernel linux-rt-lsdk-tq-5.4 with PREEMPT_RT support

Rev.0103

BSP

Switch from TMU to external sensor IC for core-cluster thermal zone

U-Boot

Fix update_pbl_spi and update_pbl_mmc scripts in U-Boot default environment. Before this fix, update_pbl_mmc was unusable.
fix CPU node FDT fixups in U-Boot not to break the thermal-zones (making the thermal driver unusable). This adds support for the TQMLS1017A to the tqmls1028a images. Both U-Boot and the Linux kernel must be updated for proper operation on TQMLS1017A.

Rev.0102

BSP

Added u-boot-lsdk-tq 2019.10 (based on LSDK 20.04)
Added kernel linux-imx-tq 5.4
The meta-freescale layer has been made mandatory for these machines

U-Boot

SD card and eMMC boot configurations have been merged and are now supported by a single image
Changed to TF-A (Trusted Firmware) boot
- The U-Boot environment for SPI-NOR boot moved to offset 5 MiB
- The U-Boot environment for eMMC/SD card boot moved to offset 8 MiB
- The PPA (Primary Protected Application) package was replaced with ATF (ARM Trusted Firmware)
- For more information about the TF-A boot process please refer to the NXP Layerscape SDK User Guide

Rev.0011
