Cortex-A7 NXP i.MX6ULL up to 900 MHz 128 - 1024 MByte NAND flash memory (8 bit bus width) or 4 - 16 GByte eMMC flash (8 bit bus width) 2 MB SPI boot flash 128 - 1024 MByte DDR3-400 On module microSD card socket (4 bit SDIO) ^[1] LC display controller, 18 bit colors, 1366x768 pixels On-chip touch controller for 4-wire resistive touch screens 2x Ethernet controller 10/100 Mbit, IEEE1588 conform ^[2] USB 2.0 OTG high-speed USB 2.0 host high speed 2x Standard UART with hardware handshake support ^[3]^[4] WiFi iEEE802.11b/g/n + Bluetooth v4.1 (BR/EDR/BLE) module on BGA ^[1]^[4] ^[1] On module microSD card socket is only available if WiFi is not mounted. ^[2] The second SPI is only available, if the second ethernet is not mounted. ^[3] CTS and RTS of the first UART is only available if second CAN port is not connected. ^[4] The second UART is only available if Bluetooth is not used. This means WiFi/BT module 1DX is not mounted or module 1FX (only WiFi) is mounted. ^[5] I²S lines are shared with JTAG.	2x CAN interface ^[3] 2x SPI interface ^[2] 2x I²C interface I²S Audio codec (1 x microphone, 1 x Line in, 1x Line out) ^[5] Real-time clock (I²C connection), low power temperature compensated 2x 10 bit analog input (I²C connection) 2x 256 Bytes EEPROM with integrated MAC address PWM channel 22 GPIOs (A-U + INT_HI_PRIO) JTAG debug connection via FFC plug connector Industrial temperature range (-40°C to +85°C) SODIMM-200 socket with DHCOM pin assignment

More on how to program it with the U-Boot command "update bootloader ..." on the page "DHCOM Update Mechanism"

More on how to use it on the page "DHCOM Update Mechanism"

Open it with Disks by double click on Debian Linux. Use balenaEtcher on Windows.

Extract the files on a USB stick (MBR / FAT32) and insert it into your board / device. More about the files on the page "DHCOM Update Mechanism"

Hint: You can also progam the eMMC by using the U-Boot command "ums" (usable since v2018.05)
