A problem that BBB is rebooted at boot time

I am using a Beaglebone black debian version 4.19.31

Beaglebone black occasionally reboots after sending the following message during booting.

U-Boot SPL 2019.01-dirty (Apr 14 2019 - 23:23:18 -0700)
Trying to boot from MMC2
Loading Environment from EXT4... Card did not respond to voltage select!

U-Boot 2019.01-dirty (Apr 14 2019 - 23:23:18 -0700)

I don’t know what’s the problem.
Input voltage is 5.0V ~ 5.5V
Could you know what’s the problem?
and what is ‘Card did not respond to voltage select!’?
How can I fix it. Please help me…


@taek8461, 5.5V? Uh-oh! The BeagleBone Black needs 5.0V as the sticker on the barrel plug shows.

Please, re-test with a different microSD card (one that didn’t get hit with 5.5V) with this specific image:



I have a feeling your going to see the exact same boot pattern, sadly your Board may have taken too much over 5.0V
