Beagleboard Flash Core Troubleshooting Tips

Over the past few weeks, several readers have informed us that they have encountered the beagleboard Flash core.

This page may be about running Debian (ARM EABIhf) on a BeagleBoard distribution. BeagleBoard will prevent Debian (ARM EABIhf) from issuing an SD card. NetInstall Debian is used to install Debian on your own Beagle.

Note. The original Beagleboards work with a Debian console image loaded by a user keystroke. Last check 05/2020. See: https://github.com/beagleboard/Latest-Images/issues/48.

  • Kernel Help:
  • Email Beagleboard End User Group *Recommended Method
  • #beagle: Beagle irc for freenode, also available via webcp trees.
  • v5 (logs)
  • kernel branch kernel.4.x
  • Beagle Bon
  • Development purchase code
  • If you need help, please provide debug information:
  • Matching the installed version of U-Boot
  • Kernel version: uname -a
  • pastebin dmesg
    • Copy from serial port or use “dmesg | pastebinit” (sudo apt-get install pastebinit)
  • http://beagleboard.org/source

  • All older Ax, Bx, Cx and Boards dx models must be updated to at least these U-Boot versions.
  • XM cards require NAND, no, so MLO/u-boot.img is usually required on the first partition e
  • Instructions: Update X-Loader and U-Boot

    • This is why we can see with the mount /dev/sda1 is the x86 root file system, the result /dev/sdd is the other disk of the new system where the main MMC/SD card was inserted, and it is supposed to stay ./setup_sdcard.sh...

    This tag can be written to another 2 GB (or larger) microSD card, such as "dd" on Linux or Windows/Mac/Linux: https://etcher.io First press and the boot selection key ( closest to all microSD cards), then turn on the power. On power up, the board should indicate that the flashing process has started successfully with the Cylon scan pattern displayed on the 4 LEDs next to the Ethernet connector. Progress is reported on both the serial debug port and the HDMI ports, after completion all nine LEDs should be fully lit. Just power down, remove that particular microSD card and Debian will now boot directly from the eMMC.

    Script for reference: (probably this will be the script from eMMC)

    https://githubthe.com/RobertCNelson/boot-scripts/blob/master/tools/eMMC/init-eMMC-flasher-v3.sh

    This script takes effect approximately 5-6 minutes after printing.

  • If even two LEDs are lit, nothing happens, the board has failed due to a lack of power. Repeat steps a with a connected 5V DC device.
  • If 4 LEDsYes blinking in a certain constant pattern, it means that the eMMC recording functions have not been completed. First remove all capes and try again.
