Embedded Artists iMX RT1062 OEM


This Embedded Artists OEM board (available for around €20) is based on the MIMXRT1052 and available in industrial and commercial temperature ranges. This 600MHz Cortex-M7 base part has double-precision VFPv5 FPU in MAPBGA196 package. It has 1M of internal RAM, an external memory interface, dual-10/100M Ethernet, dual-high speed USB (with integrated PHY), 8 low power UARTs, 4 I2C controllers, 3 synchronous audio interfaces, 2 SD card interfaces, 2 CAN interfaces, 2 FlexSPI interfaces (the principal one connected to 4MByte QSPI flash), 2 ADC and LCD controller, a True Random Number Generator, plus various other features.

The processor's budget price for 10'000 pieces is $3.48 (low quantity distributor price for 100 pieces under $9), potentially making it very attractive for low cost products requiring connectivity, HDI, high processing performance and audio.

A 24MHz crystal on the board allows for accurate generation of up to 600MHz processor, 100MHz Ethernet and 480MHz USB clocks.

The µTasker target for the iMX RT1062 OEM allows immediate use of the board for various functions with simple control of performance/consumption as well as the ability to switch operation between this and other i.MX board/processors and Kinetis parts. Accurate simulation of the device in VisualStudio combined with integrated µTasker application functionality ensures reliable, low footprint product development solutions with minimum effort, risk and investment.



iMX RT1062 OEM Binaries

Here are some binary files that can be loaded to the board. These were built using the µTasker applications (serial loader and V1.4 application) and can be simply generated using the supported compilers/IDEs [these were built using GCC], built using different configuration options or modified to suit specific requirements or hardware derived from this board :
  • uTaskerSerialLoader_i.MX-RT1062_OEM_USB-MSD_Kboot-HID_SREC-UART_SD-Card_AES256.bin [54.4k]
    HS USB-MSD / KBOOT-HID composite USB bootloader, including SREC UART loader on the board's VCOM UART which can be loaded (copied to its QSPI-Flash) using your favorite loading tool - for example NXP MCUBootUtility.
    This boot loader enables uploading applications by one of four methods:
    - USB-MSD drag-and-drop onto the external hard drive that appears when the processor's USB is connected to a host PC
    - KBOOT-HID (compatible with the NXP protocol and loading tools, such as KinetisFlashTool) via USB-HID
    - SREC-UART (connected at 115'200Baud on the board's VCOM UART)
    - SD-Card
    This version of the serial loader supports either AES256 encrypted applications or non-encyrpted ones. In addition the serial loader itself is stored in an AES256 encrypted form in the QSPI flash. The same application, in plain-text and encrypted forms are below, in order to allow testing this.

    To force the loader when there is already an application installed, reset the board with the USER button SW8, held down. When operating, the green LED blinks at 5Hz. Beware that the SD card content will be checked for new firmware and the application will start after the check if it exists; to stay in the serial loader mode hold the USER button down for about 3..4s.
    To quit the loader mode to start an installed application the USB-MSD driver can be simply ejected by the host. Alternatively the "go" command can be executed on the LPUART connection.
    The serial loaders are described in the µTasker Serial Loader guide

  • uTaskerV1.4.12_i.MX-RT1062_OEM_USB-SD-Card.bin [60.4k]
    This i.MX RT 1062 OEM application shows SD card and USB-MSD / USB-CDC composite operation. It has a command-line menu on LPUART 1 (via the board's virtual COM port connection at 115'200 Baud) or on USB-CDC with utFAT disk interface to control an SD card inserted in the board's socket. The disk interface is accessed via menu item 8 and offers a DOS-like user interface to display directories and files, plus advanced commands to view file details and read/write raw sectors on the disk:
       Disk interface
    ===================
    up           go to main menu
    info         utFAT/card info
    dir          [path] show directory content
    dird         [path] show deleted directory content
    dirh         [path] show hidden content
    infof        [path] show file info
    infod        [path] show deleted info
    cd           [path] change dir. (.. for up)
    comp         compare [file1] with [file2]
    file         [path] new empty file
    write        [path] test write to file
    mkdir        new empty dir
    rename       [from] [to] rename
    trunc        truncate to [length] [path]
    copy         [file1] to [file2]
    hide         [path] file/dir to hide
    unhide       [path] file/dir to un-hide
    prot         [path] file/dir to write-protect
    unprot       [path] file/dir to un-protect
    print        [path] print file content
    del          [path] delete file or dir.
    sect         [hex no.] display sector
    sectw        [hex no.] [offset] [val] [cnt]
    help         Display menu specific help
    quit         Leave command mode
    

    The SD card also appears as an external hard drive to the PC host. A second USB-MSD disk allows the viewing of memory (ITC, DTC and QSPI flash) based on FAT emulation as described in µTasker - FAT emulation

    This unencrypted binary file can be loaded after installing the µTasker bootloader (above) via USB-MSD or KBOOT-HID. It can also be copied to the SD card and given the name "software.bin" so that it will be loaded by the serial loader.

  • uTaskerV1.4.12_i.MX-RT1062_OEM_USB-SD-Card.srec [163k]
    SREC formatted version of the application, which can be loaded by transferring via the LPUART interface.
  • uTaskerV1.4.12_i.MX-RT1062_OEM_USB-SD-Card_AES256.bin [60.6k]
    This is the same i.MX RT 1062 OEM application but in an AES256 encrypted form. This can also be loaded in the same ways as the un-encrypted one, whereby the boot loader recognised whether it is encrypted or not and handles it accordingly. The encrypted version of the application ensures that it can't be retrieved from the QSPI flash and reverse engineered.
  • uTaskerV1.4.12_i.MX-RT1062_OEM_USB-SD-Card_AES256.srec [163k]
    SREC formatted version of the AES256 encrypted application, which can be loaded by transferring via the LPUART interface.
