ETRA SOM is part of DAVE Embedded Systems' portfolio of system on modules based on ST Microelectronics's solutions and it can be provided with ST STM32MP1 System On Chip.
This System On Chip is designed with ARM Cortex-A7 plus a Cortex-M architecture integrated together.
This System On Module is designed to support a compatibility within the existing AXEL ULite System On Module based on NXP i.MX6 UL System On Chip enabling and easy update of all existing products but and the generation of new solutions based on a brand new bot product with 15 years availability within industrial qualification.
ETRA SOM has the same form factor, the same size and a compatible pinout with AXEL ULite System On Module. This SOM permits to use all functionalities available from the System On Chip.
Starting from the ARM Cortex-A7 architecture with up to 2 cores available and the Cortex-M4 the ETRA SOM System On module integrates on board a single chip DDR3 and multiple choices for storage.
ETRA SOM main characteristics are:
Yes. ETRA Evaluation Kit is the official support platform for evaluation the ETRA SOM. It includes a SOM and all the necessary for the fast and easy evaluation.
The ETRA SOM Evaluation Kit includes:
On this page you can find ETRA SOM 3D model.
On this page you can find ETRA SOM block diagram.
On this page you can find all the ETRA SOM hardware documentation available.
On this page you can find all the ETRA SOM marketing documentation available.
ETRA SOM module part number is identified by the digit-code table that you can find here.
ETRA SOM, as a part of the SMT32MP1 family, is included in the 10 years longevity program by ST Microelectronics.
For further information, see this page.
DAVE Embedded Systems' goal is to grant the production continuity to its customer including the possibility to redesign its products in order to maintain the product continuity.
If you want to request support to our technical team please fill this form. After the submission, a ticket will be assigned. Our technicians will look after your request and typically they will respond you via email within 24 hours from the request.
We hope you don’t need it! Here you can find the DAVE Embedded Systems' Return Material Authorization form.
Yes. You can download a PDF version of ETRA SOM hardware manual by clicking here.
ETRA SOM processor and memory subsystem are composed by the following components:
For further information, see this page.
Yes. The PCB version is copper printed on PCB itself and the serial number is printed on a white label (please see here for further information).
Also, a ConfigID is used by software running on the board for the identification of the product model/hardware configuration. Refer to this link for more details.
On this page you can find the connectors and pinout description of the ETRA SOM.
On ETRA SOM are available the following peripherals:
Implementing correct power-up sequence for STM32MP1 processors is not a trivial task because several power rails are involved. ETRA SOM ncludes a PMIC that manage all the power on and poweroff timings to ensure the correct sequence. On this page you can find a simplified block diagram of PSU circuitry.
The typical power-up sequence is the following:
For further information, see this page.
On this page 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:
On this page you can find further information about ETRA SOM boot options.
JTAG signals are routed to the primary ETRA connector J1.
Here you can find the table that reports the connector’s pinout.
For further information on how to use the JTAG interface, please contact DAVE Embedded Systems Technical Support Team.
Here you can find ETRA SOM’s maximum ratings, recommended ratings and power consumption.
The ETRA 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.
On this page you can find the mechanical characteristics of ETRA SOM.
Yes. DAVE Embedded Software Kit Linux (DESK-MP1-L in short) is available for ETRA SOM and it provides all the necessary components required to set up the developing environment to:

DAVE Embedded Systems strongly recommend to register your kit. Registration grants access to reserved material such as source code and additional documentation.
To register your kit, please send an email to helpdesk@dave.eu providing the kit P/N and S/N.
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 further information about ConfigID and UniqueID, see this page.
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.
See this page for further information on how to simply configure the network interface.
On this page you can find useful information and resources to system designers in order to design carrier boards hosting DAVE Embedded Systems system-on-modules (SOM).
These guidelines are provided with the goal to help designers to design compliant systems with DAVE Embedded Systems modules and they cover schematics and PCB aspects.
