I’ve been experimenting with different SD card images and something I don’t understand…probably completely simple…it seems any OpenROV images or stock BBB images on an SD Card will boot from the SD card automatically, without holding down the S2 button during power on. I’ve tried this after disconnecting power completely. I’m pretty sure this is the case (my SD card has files on it that do not exist on the emmc). I also see the blue LED representing SD card access going wild, nothing on the blue emmc LED.
If I load up, say, an Ubuntu Beaglebone image, the TI SDK image…I can only get the SD card to boot when holding down the switch.
The load in emmc for me right now is the stock BBB image.
Do the OpenROV/Stock SD Card images really manage to cause a boot from the SD card? The common thread between the two is Debian.
Any insight as to how this works or confirmation that I’m crazy and this can’t really happen is appreciated.
