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.

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

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 ....
