For further information, see this page.
All interface signals SMARX – DSX provides are routed through 314-pin edge connector (named J10) as per SMARC specifications 1.0. The dedicated carrier board must mount the mating connector and connect the desired peripheral interfaces according to SMARX - DSX pinout specifications.
SMARX provides an additional optional connector for JTAG interface.
For further information, see the Hardware Manual.
Yes. SMARX SOM implements well established versioning and tracking mechanisms.
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. On SMARX – DSX SOM ConfigID is stored in these areas of OTP memory region integrated in the i.MX6 SOC:
The UniqueID is a read-only code which univocally identifies the part. It can be read by software as described here.
Implementing correct power-up sequence for i.MX6 processors is not a trivial task because several power rails are involved. SMARX - DSX SOM simplifies this task by embedding all the required circuitry.
Here you can find a simplified block diagram of block diagram of power supply subsystem.
The PSU is composed of three main blocks:
The PSU:
The recommended power-up sequence is:
1. (optional) VDD_RTC is powered
2. VDD_IO_SEL must be left floating in order select 3.3V I/O as per SMARC v1.0 standard and to allow SMARX – DSX SOM to power up correctly
3. VDD_IN main power supply rail is powered
4. Carrier Board releases VIN_PWR_BAD# signal when it supply a stable voltage to SOM through VDD_IN power rail. Optionally this signal can be left floating.
5. RESET_IN# (active-low) is driven low
6. PMIC transitions from OFF to ON state
7. PMIC initiates power-up sequence needed by MX6 processor
8. CARRIER_PWR_ON signal is raised; this active-high signal indicates that SoM's I/O is powered. This signal can be used to manage carrier board power up sequence in order to prevent back powering (from SoM to carrier board or vice versa)
9. RESET_IN# is released.
For further information, see this page.
On this page you can find a block diagram of reset scheme and voltage monitoring.
On SMARX - DSX SOM the three BOOT_SEL[2:0] pins allow to select from different boot devices.
To select the Boot Device the BOOT_SEL[2:0] signals must be tied to logic levels '0' or '1' at SOM power-on. This is accomplished by tying to GND or pull-up to nominal 3.3V_I/O present on the carrier board. The BOOT_SEL[2:0] signals belongs to CPLD_I/O_3.3V voltage domain. Details about voltage levels threshold please refer to section 4.1.3.2 CPLD_I/O_3.3V.

The i.MX6 provides debug access via a standard JTAG (IEEE 1149.1) debug interface. The signals are routed to the on-board J7 connector.
The connector is placed on the top side of the PCB, at the upper-left corner as shown on this page.

For further information, see this page.
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-MX6-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.
Check this page for further information on how to keep the source trees in sync and up to date with DAVE Embedded Systems’ git repositories.
See this page for further information on how to build the U-Boot bootloader on DESK-MX6-L (Software Development Kit for SMARX SOM).
See this page for further information on how to build the Linux kernel on DESK-MX6-L (Software Development Kit for SMARX 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.
To generate the supported root file systems, the build of the Yocto BSP has to be run. The output of this process is an image containing the U-Boot binary file, the Linux kernel image, and the selected root file system image. See this page for further information on how to build the Yocto BSP on DESK-MX6-L.
See this page for further information on how to create a bootable microSD for the DESK-MX6-L kit 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.
With respect to the NOR flash memories, NAND devices are known to be quite challenging 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.
This page provides information about the NAND device management, in order to handle it properly when it is used as the boot device on NXP i.MX6-based products.
Please refer to our video tutorial How to program U-Boot in NAND flash for detailed instructions on how to program and U-Boot on internal NAND flash.
On this page you can find further information on how to customize the splash screen on DESK-MX6-L (Software Development Kit for SMARX SOM).
Please refer to our video tutorial How to change the U-Boot splash screen on SD card for detailed instructions on how to use your own company logo as a U-Boot splash screen.
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.
The page contains general concepts that can be adapted on any DAVE Embedded Systems' Linux platform.
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.
See this page for further information on how to simply configure the network interface or watch our tutorial How to configure the network interface.
