I’m trying to get a Linux image onto SABRE platform MCIMX6DL-SDP. Running Android from the supplied SD card works fine, but I don’t manage to get Linux running. What I did is the following:

  1. Set SW6 to “00001100” (USB OTG mode)
  2. Place empty SD card into J507 (SD3)
  3. Connect PC via Micro-USB cable to J505 for downloading and to J503 for terminal output
  4. Use the MfgTool (Mfgtools-Rel-4.1.0_130816_MX6DL_UPDATER) with the setting (cfg.ini)



chip = MX6DL Linux Update


board = SabreSD



     5. Exit MfgTool after „DONE“ is displayed via „Stop“ and „Exit“

     6. Swith SW6 to “01000010”

     7. Restart the board

It seems as if U-Boot is looking for the OS via Network, can I change this somehow?


Also, I can’t stop autobooting by hitting any key (power, volume up/down)…


I used the manuals “i.MX_6DualQuad_SABRE-SD_Linux_Users_Guide.pdf” or “i.MX Development Quick Start-FAE-V3.pdf” – did I use the wrong manuals or do something else wrong?


Kind regards,
