Working with SECO Amston Lake platform

The SECO Amston Lake platform uses many of the same sources and binaries provided for the generic BSP, with a few differences. This BSP was developed and validated on the SECO Amston Lake SOM-SMARC-ASL (CSE08REVB - L1 config) with Carrier-SM-B79 (CSB79REVB), using UEFI firmware - version 1.00.00.

Using SECO Amston Lake (SOM-SMARC-ASL) on Carrier-SM-B79 platform

For information about the hardware setup, updating the BIOS, documentation, and so on, refer to SOM-SMARC-ASL and Carrier-SM-B79.

Connecting power supply to SECO Carrier-SM-B79 platform

Connect the power supply to the CN3 power connector.

Connecting UART port to SECO Amston Lake (SOM-SMARC-ASL) on Carrier-SM-B79 platform

Use the provided 9-pin to DB9 splitter with a DB9 female serial cable to connect the CN25 Feature Header on the CSM-B79 to your host machine. Make sure that SW7 [1-3] is in OFF position.

On your host machine, using terminal software and an appropriate COM port, typical settings for use with SECO Amston Lake (SOM-SMARC-ASL) on CSM-B79 board would be:

  • Baud rate: 115200
  • Data: 8 bit
  • Stop: 1 bit
  • Parity: no
  • Flow control: none

Modifying the QNX IFS image for SECO Amston Lake platform

By default, the x86_64-seco-amstonlake-uefi.build buildfile generates an IFS image that can be used to boot SECO Amston Lake board. The x86_64-seco-amstonlake-uefi.efi IFS image is found in the $BSP_ROOT_DIR/images/amston-lake directory. To see what's included in the default IFS images, you can view the buildfiles.

Boot SECO Amston Lake (SOM-SMARC-ASL) on CSM-B79 board

Booting a SECO Amston Lake (SOM-SMARC-ASL) on CSM-B79 board follows these steps:
  1. Copy the QNX IFS image x86_64-seco-amstonlake-uefi.build to a DOS-formatted USB stick as the file name /EFI/BOOT/BOOTX64.EFI.
  2. Insert the USB stick to any USB port on the target board.
  3. Turn on the power and configure the BIOS to boot from UEFI USB device.
