BBG Getting Started step5

Hi,
Maybe this is a silly question?
I followed Getting Started step1 to step5.
And I have been running BBG booted from eMMC with SD card removed.
In the meantime, I kept update/upgrade on eMMC.
NOW I got BBG BRICKED.

How should I do to recover BBG by putting in SD card without delete all the upgrade/update on eMMC?
NOTE: AS the /boot/uEnv.txt file already change(STEP5 of Getting Started) to flash the eMMC.

Hi there,

You can boot from sd card and then modify /boot/uEnv.txt to enable emmc flasher. When the flashing is complete, all 4 USRx LEDs will be off. The latest Debian flasher images automatically power down the board upon completion. This can take up to 10 minutes. Power-down your board, remove the SD card and apply power again to be complete. thanks.

Code: Select all

##enable BBB: eMMC Flasher:
cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh

Thank for suggestion!
What if I would like to get the eMMC back to bootable but not reflash it!
I really want to figure out what happened !!
Maybe due to virtual machine or using up all the eMMC space or ....

Hi Charles

You can extract the files out and them check the logs to find the root cause. here is the process how to extract emmc contents. thanks.
