Debug Connection
The TQMa8MPxL debug UART is connected via a FTDI USB-to-Serial converter to X28 (micro-USB) on the MBa8MPxL. A micro-USB/USB-A cable for the connection to the host PC is part of the STKa8MPxL accessory set.
Depending on the host operating system, the USB-to-serial converter driver may need to be installed.

Yocto Changelog
BSP Version History
Rev.0092
Rev.0091
Rev.0090
Rev.0089
Added
- Machines:
- MBa93xx[CA,LA] preparation for using with Quectel GSM/LTE modem
- Support for TQMa93xxCA on MBa93xxCA was added. This SOM shares U-Boot and devicetree with TQMa93xxLA on adaptor. Machine
tqma93xxla-mba93xxca
was therefore renamed totqma93xx-mba93xxca
- Support for TQMa93xxLA on MBa93xxLA was added. The machine config files for TQMa93xxLA on MBa93xxCA were restructured to allow sharing settings for the boards. This prevents copy and paste and allows quickly adding new boards.
- linux-imx-tq 5.15 / imx on arm64:
- enable support of GSM/LTE modules connected via USB. Tested with Quectel EC21.
- enable RFKILL support in kernel config
- TQMLS1046A: add machine config for RAM without ECC
- TQMLS1046A: add u-boot-tq-2018.07 configs for Modules without ECC
- TQMa93xxLA: add wifi and bluetooth to
MACHINE_FEATURES
and enable firmware for WLAN cards with 88W8997 chipset - TQMa8X[xS]: Known issue regarding hardware controlled chip-select
- TQMT10xx: add initial support for TQMT10xx based machines:
- tqmt1040-64bit-stkt104x
- tqmt1042-64bit-stkt104x
- tqmt1022-64bit-stkt104x
- tqmt1024-64bit-stkt104x
Fixed
- TQMa64xxL: enable SDHC controller quirk to fix SD card access on TQMa64xxL REV.010x SoMs.
- all machines: Fix a race condition due to missing dependencies for
WKS_FILE_DEPENDS
. AddEXTRA_IMAGEDEPENDS
toWKS_FILE_DEPENDS
for all machines. - TQMa8MPxL: fix disabling of devices when no VARD can be used. Rather than dis- abling all optional devices, print a warning and try to boot. Without the warning this restores the behaviour before handling optional devices with VARD.
- machines: fix display related features in
MACHINE_FEATURES
Usescreen
andtouchscreen
since this is what Yocto Project / OpenEmbedded use. Removedisplay
which was in use solely in TQ-Systems layers. - machines: clean
WKS_FILE_DEPENDS
and make sure it contains e2fsprogs-native. This prevents ext4 build errors during wix image creation. This kind of error occurs repeatedly when ext4 is not part ofIMAGE_FSTYPES
Additionally move all non host tools dependencies fromWKS_FILE_DEPENDS
toEXTRA_IMAGEDEPENDS
- MBa8Xx[S]: linux-imx-tq 5.15:
- Pull-up configured for SPI chip-selects in kernel devicetree
- use gpio chip select for SPI where possible to prevent toggling chip select due to SPI IP and DMA limitation
- linux-firmware: fix for multilib configurations
Removed
- Adjust and mostly remove recipes ported from meta-imx for i.MX93 support. These are ported to meta-freescale as of commit 642cf7f2 ("Merge pull request #1433 from Freescale/backport-1432-to-kirkstone")
- fm-ucode recipe removed and append for meta-freescale recipe added instead.
Changed
- TQMLS102xA
- improve settings for U-Boot specific variables
- allow easier usage with different RCW
- u-boot-tq_2017.11: simplify recipe for TQMLS102xA
- imx-sc-firmware-tq_1.13.0 (TQMa8X[D,Q]P[S], TQMa8QM)
- update to TQMa8.NXP-v1.13.0.B5561.0035
- Improve DRAM memory region protection: only existing DRAM is partitioned
- Move recipe out of dynamic-layers/freescale-layer. Since we provide our own binary package without dependencies to other layers the recipe does not need to be hidden.
- linux-tq 6.1 / TQMa8M: update to 6.1.9
- linux-imx-tq 5.15 / TQMa93xxLA:
- cleanup gpio for LVDS on MBa93xxCA, make USB touch working
- rename DT and compatible for MBa93xxCA
- u-boot-imx-tq 2022.04 / TQMa93xxLA
- rename board and config names for MBa93xxCA
- rename DT for MBa93xxCA
- tqma57xx: update machine configuration and bbappends for compatibility with latest meta-ti kirkstone (as of commit 38941472e1e3 "meta-ti-bsp: add BeagleBone AI-64 support")
- machines: improve usage of bitbake variables to express image dependencies Move packages from
IMAGE_INSTALL:append
toMACHINE_EXTRA_RRECOMMEND
in machine config files. - all imx based SOM: port changes from meta-imx kirkstone-5.15.71-2.2.0 in libdrm, weston, wayland-protocols as bbappend-files under dynamic layers to get the latest changes needed for imx93
- TQMa93xxLA: port and configure more graphic support from meta-imx
- TQMa93xxLA: rename starter kit mainboard to MBa93xxCA, therefore machine name is now tqma93xxla-mba93xxca
- u-boot-imx-tq 2022.04 / TQMa93xxLA
- improve VARD support, fixup devictree
- improve QSPI NOR support
- speed grade / temperature grade handling
- linux-imx-tq 5.15:
- TQMa93xxLA: LVDS support, QSPI support, USB at mPCIe slot,
- enable enable marvel / nxp wifi driver in wifi support fragment
- enable PWM driver needed for i.MX93
- TQMa93xxLA: update firmware-imx-9 to 8.18. Needs at least meta-freescale commit 8bd13d69 ("firmware-imx: Upgrade 8.17 -> 8.18")
Rev.0088
BSP
- Update to Yocto Kirkstone 4.0.6
- Allow kernel image to be installed in rootfs per default
- Rewrite logic for KERNEL_DEVICETREE and device trees in IMAGE_BOOT_FILES. This removes the intermidiate variable BOARD_DEVICETREE_FILES

Devices may be assembled optionally on SOM. Use variant and revision data to enable / disable devices in device tree based on VARD. This prevents the OS from probing / accessing not assembled devices - Add nfs boot script to boot from network without TFTP server
- Cleanup default Environment

- create the environment variable rootblks16 and set the value accordingly to the size of the RootFS in this case 627 MB.
To calculate the value of rootblks16 devide the size of the image in byte by 512 and convert the result into a hex value.
627 * 1024 * 1024 = 657457152
657457152 / 512 = 1284096
1284096 = 139800HEX
setenv rootblks16 0x139800
