The MITO 8M SOM product is based on the recent NXP i.MX8M application processor. Thanks to this solution, customers have the chance to save time and resources by using a compact solution that permits to reach scalable performance that perfectly fits the application requirements avoiding complexities on the carrier board.

i.MX8M SOM is compatible with i.MX6 SOM solution AXEL Lite. Customers that want to migrate from previous i.MX6 solution to this new will have a zero-effort approach with the great advantage of performance.

Also, it is designed in order to keep full compatibility with the LITE Line CPU modules, for design where quality and reliability are important factors.

The use of this processor enables extensive system-level differentiation of new applications in many industry fields, where high-performance and extremely compact form factor (67,5 mm x 43 mm) are key factors. i.MX8M SOM offers great computational power, thanks to the rich set of peripherals, the scalable ARM Cortex-A53 together with a large set of high-speed I/Os such as dual PCle and USB3.

iMX8 SOM enables designers to create smart products suitable for harsh mechanical and thermal environments, allowing for the development of high computing and reliable solutions.

Implementing correct power-up sequence for iMX8M processors is not a trivial task because several power rails are involved. MITO 8M SOM simplifies this task by embedding all the needed circuitry. Here you can find a simplified block diagram of PSU/voltage monitoring circuitry.

The PSU is composed of two main blocks: 1) power management integrated circuit 2) additional generic power management circuitry that completes PMIC functionalities. It generates the proper power-up sequence required by the SOC processor and surrounding memories and peripherals and synchronizes the powering up of carrier board in order to prevent back power.

The typical power-up sequence is the following:

1. 3.3VIN main power supply rail is powered
2. SNVS domain signals are pulled-up (unless carrier board circuitry keeps this signal low for any reason)
3. CPU_PORn (active-low) is driven low by PMIC
4. RTC_RESET_B are internally released after 200ms
5. VDD_SOC regulator starts and enables the VDD_ARM and PMIC regulators
6. PMIC initiates power-up sequence needed by iMX8M processor
7. BOARD_PGOOD goes up when NVCC_3V3 (CPU I/O power rail) is ready
8. CPU_PORn is deasserted after the last regulator to bring the processor out of reset

See this page for further information.

On this page you can find a block diagram of reset scheme and voltage monitoring for MITO 8M SOM.

The boot process begins at Power On Reset (POR) where the hardware reset logic forces the ARM core to begin execution starting from the on-chip boot ROM.

The boot ROM:

• determines whether the boot is secure or non-secure
• performs some initialization of the system and clean-ups
• reads the mode pins to determine the primary boot device
• once it is satisfied, it executes the boot code

JTAG signals are routed to a dedicated connector on the MITO 8M PCB. The connector is placed on the top side of the PCB, on the right side.
Check out this page for further information.

On this page you can find MITO 8M SOM maximum ratings, recommended ratings and power consumption.

The MITO 8M SOM is designed to support the maximum available temperature range declared by the manufacturer. The customer shall define and conduct a reasonable number of tests and verification in order to qualify the DUT capabilities to manage the heat dissipation. Any heatsink, fan etc shall be defined case by case.

DAVE Embedded Systems' team is available for any additional information, please contact sales@dave.eu or check this page for further information.

Yes. ConfigID is a new feature of DAVE Embedded Systems products. Its main purpose is providing an automatic mechanism for the identification of the product model and configuration. In simple words, model identification means the capability of reading a numerical code, stored in an available device (SOC's OTP , I2C EEPROM, 1-wire memories, protected NOR flash, etc.)

With ConfigID, we aim at completing the hardware configuration information that the software can't normally auto-detect (i.e. RAM chip version,...), implementing a dedicated reliable detect procedure and, when required, overriding the auto-detected hardware configuration information.

This article describes how the ConfigID is implemented in the products supported by the DESK-MX8M-L Linux Kit.

An additional attribute is UniqueID, which is a read-only code which univocally identifies a single product and is used for traceability.

For further information, see this page.

Yes. This configuration is very helpful during the software development (both for kernel and applications). The kernel image is downloaded via TFTP while the root file system is remotely mounted via NFS from the host.

For further information, see this page.

On this page you will find the detailed explanation on how to keep in sync and up to date the source trees with DAVE Embedded Systems' repositories on DESK-MX8M-L (Software Development Kit for MITO 8M SOM).

Access to DAVE Embedded Systems' git repositories is granted to the development kit's owners only. Please refer to our video tutorial How to access DAVE Embedded Systems' git repositories for detailed instructions on how to get access.

See this page for further information on how to build the Boot image on DESK-MX8M-L (Software Development Kit for MITO 8M SOM).

See this page for further information on how to build the U-Boot bootloader with make on DESK-MX8M-L (Software Development Kit for MITO 8M SOM).

See this page for further information on how to build the Linux kernel on DESK-MX8M-L (Software Development Kit for MITO 8M SOM).

Please refer to our video tutorial How to add a new kernel device driver (build the kernel) for detailed instructions on how to do it.

As known, in addition to a bootloader and the o.s. kernel, an embedded Linux system needs a root file system to operate. The root file system must contain everything needed to support the Linux system (applications, settings, data, etc.). The root file system is the file system that is contained on the same partition on which the root directory is located.

DESK-MX8M-L provides one (or more) pre-built root file system, that can be used during the evaluation/development/deployment cycle.

Check this page for further information on how to build the Yocto BSP on DESK-MX8M-L.

Check this page for further information on how to create a bootable microSD for the DESK-MX8M-L (Software Development Kit for MITO 8M SOM) by using a simple bash script.

In this video tutorial we guide you step by step in creating a bootable SD card from scratch.

Yes. On this page you can find an example on C code displaying the classic Hello World! message on the target serial console. This example shows how to use the arm cross-compiler using the environment configured for this purpose.

On this page you can find how to program and configure a SOM to boot in standalone mode, without the need of a system microSD card or an NFS server.

Please refer to our video tutorial How to program the NAND flash for a standalone boot for detailed instructions on how to do it.

For deploying an Embedded System, one of the most important configuration is the Network Interface configuration.

Once the Embedded Device is finally configured for stand-alone bootstrap, the network interface should be configured for reaching the device remotely via network connections like ssh, telnet, ftp, http, etc.

Check this page for further information on how to simply configure the network interface on SystemV (aka SysV) or systemd or watch our tutorial How to configure the network interface.

Every network adapter has a Media Access Control address (usually shortened to MAC address). A MAC address is a six-byte identifying number permanently embedded in the firmware of the adapter, and is readable by the network and the operating system of the device on which the adapter is installed.

The address must follow the standards set by the Institute of Electrical and Electronics Engineers (IEEE), which sets computer networking standards.

On this page it is described how to use the i.MX8M eFuse for programming and using the MAC address(es) and it applies to the following DAVE i.MX8M family products.

On DESK-MX8M-L (Software Development Kit for MITO 8M SOM) are available the following peripherals:
