    Can Not Flashing new BeagleBone from Embest

    shimon

      Last year I worked with BeagleBone Black from element14. I prepared image configured as I need, and burn it.

      Burning process was as described here : https://elinux.org/Thread:Talk:BeagleBone_Black_Extracting_eMMC_contents/Flash_unsuccessful

       

      It mean: I downloaded and burned package with u-boot.img and other necessary files which at start up runs script:

       

      #!/bin/sh

      echo timer > /sys/class/leds/beaglebone\:green\:usr0/trigger

       

      #un-comment the following line to perform a backup

      #dd if=/dev/mmcblk1 bs=16M | gzip -c > /mnt/BBB-eMMC-$RANDOM.img.gz

       

      #un-comment the following 6 lines to perform a restore (be sure to replace XXXXX with your image name)

      gunzip -c /mnt/BBB-eMMC-XXXXX.img.gz | dd of=/dev/mmcblk1 bs=16M

      UUID=$(/sbin/blkid -c /dev/null -s UUID -o value /dev/mmcblk1p2)

      mkdir -p /mnt

      mount /dev/mmcblk1p2 /mnt

      sed -i "s/^uuid=.*\$/uuid=$UUID/" /mnt/boot/uEnv.txt

      umount /mnt

       

      sync

      echo default-on > /sys/class/leds/beaglebone\:green\:usr0/trigger

       

         But last time I got cards from Embest and that procedure not worked.

      When I try to start from SD Card with my image BBB works properly, but when I try to flash eMMC from /boot/uEnv.txt, after flashing I got errors, and message, that system can not find disk.

       

      Last Debian (9.1)image flashed correctly.

      Please, help.

          I have spent the last 4 days trying to flash eMMC memory to an
          Embest Element14 Beaglebone Black. I have followed all there instructions.
          Nothing worked for ther product. I have bought 10 and am returning them
          To the manufacturer for a refund.
             I have never seen such garbage put out using the BeagleBone.org logo
          As is been put out by Embest Element14, they are going to end up destroying
          The Beaglebone Black brand name.
             Good luck to them, as for me I am moving on. They don’t even offer a solution on their web site.

          Thanks

            Shimon,

             

            There was a change in the eMMC (JEDEC 5.1) as the previous version (JEDEC 5.0) was EOL’d. Older kernels do not support JEDEC 5.1 so you will need to update to Debian Image 7.11 or later for compatibility. You can also use older image and upgrade the kernel.

            Please follow the instructions in the following link:

            https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Kernel_Upgrade

             

            cd /opt/scripts/tools/

            git pull

            sudo ./update_kernel.sh

            sudo reboot
