NXP i.MX8M Mini / Nano SOM is the new top-class Quad Core ARM Cortex-A53 CPU module by DAVE Embedded Systems, based on the recent NXP i.MX8 Mini / Nano application processor. The background idea with this new SOM provided by DAVE Embedded Systems is to provide customers within a FULL compatible solution with existing NXP i.MX6 Solution. With this concept, customers will be enable to jump on this new solution obtaining immediately:
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.MX8 Mini / Nano SOM offers great computational power with a reasonable price. For these reasons it is the right alternative to NXP i.MX6 Solutions. The main features of this new product are:
i.MX8M Mini 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 us dual PCIe and USB3.
i.MX8M Mini SOM is compatible witth 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. i.MX8 SOM enables designers to create smart products suitable for harsh mechanical and thermal environments, allowing for the development of high computing and reliable solutions.
Thanks to the tight integration between the ARM Core-based processing system and the RTOS integrated on board, designers are able to share the applications through the multicore platform and/or to divide the task on different cores in order to match with specific application requirements. i.MX8M Mini SOM is designed in order to keep full compatibility with the LITE Line CPU modules, for designs where quality and reliability are important factors PLUS compatibility of AXEL LITE SOM.

MITO 8M Mini SOM supports the following peripherals:
Implementing correct power-up sequence for iMX8M Mini/Nano processors is not a trivial task because several power rails are involved. MITO 8M Mini 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 synchronizes the powering up of carrier board in order to prevent back power.
The typical power-up sequence is the following:
Here you can find a block diagram of reset scheme and voltage monitoring.
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:

For accessing the restricted git repositories, it is requested to provide a ssh key that will be used for retrieving the source codes: in this video we show you how to provide it.
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.
An additional attribute is UniqueID, which is a read-only code which univocally identifies a single product and is used for traceability.
For more information about DESK-MX8M-L ConfigID and UniqueID, see this page.

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

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.
Yes, it is. MITO 8M Mini SOM is designed to support different bootable storage devices.
The usage of NOR flash memories, NAND devices and eMMC devices can be chosen with regard to the reliability. This is especially true when the NAND flash is used as the boot device. Several techniques such as wear leveling and bad block management have to be implemented to achieve an acceptable reliability.
Please check the MITO 8M Mini P/N composition page for the storage devices available on the SOM or contact our technical support for more information.
DAVE Embedded Systems provides a very efficient technical support via a helpdesk ticketing system. In this video we show you all the ways you can get help from us: How to contact DAVE technical support.
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.
