This board development started in April 2021 and finished August 2021 but the semiconductor shortages didn’t allow us to test the prototypes until recently. We assembled 4 boards and all theyare alive and boot.
The features are:
MIMX8ML8DVNLZAB – Quad Core Arm Cortex-A53 running at 1.8Ghz with Arm Cortex-M7 co-processor running at 800Mhz and 2.3 TOPS Neural Processing Unit.
6GB LPDDR4 RAM
Power management
configuration EEPROM
status LED
LCD LVDS connector compatible with LCD-OLinuXino displays
MIPI DSI connector
2x MIPI CSI comera connectors with Raspberry Pi compatible pinout
220 signals on 6 0.05″ step connectors with essential peripherials like:
PCIe-3.0
2x CAN FD
HDMI 2.0a
SPDIF
SAI
2x USB 3.0
2x Gigabit Ethernet one of them with TSN
eMMC 5.1
SDIO 3.0 200Mhz
4 UART
6 I2C
3 SPI
JTAG
Unfortunately we only managed to find 24Gb LPDDR4 for the prototypes so instead of 6GB they are with only 3GB of RAM.
Now is time to prepare Linux and Android images! NXP provide iMX8MPlus with Linux Kernel 5.10 and Android 11.
The PCB routing of our most complex board – IMX8QM-Tukhla is complete and ready for first prototype build.
We started this project June-July 2020. Due to the Covid19 the development took 10 months although only 6 month of active work was done, due to lock downs, ill developers and so on troubles.
Now the board is completely routed and has these features:
Main SOC MIMX8QM5AVUFFAB which is member of iMX8 Quad Max series – the most powerful iMX8 SOC line from NXP.
MIMX8QM5AVUFFAB has 8 cores:

To the best of our knowledge there is no Open Source Board so far which to be so complex and advanced.
Now we are running the first prototypes and crossing fingers everything to work 🙂
With the current state of the semiconductor industry production will not be possible to be run soon.
Linux support will need attention as NXP has no mainline Linux for this SOC, but only Yocto build for old kernel (4.14.98_2.3.3).
If there are people with experience and interest in this SOC we may share one of the first samples we build, so they can help on the Linux support.
The schematic of IMX8QM-TUKHLA Revision A is uploaded for review on out ftp.
