I've got a BBB powered from a battery via USB, and then a barrel connector providing power from a power supply. At startup, the power supply is off, thus the need for the battery in order to boot. Once the BBB is up, it checks some sensors, and if all is well, starts the power supply via relay.
<Guest4494>
When the BBB detects power on the barrel connector, it switches to that for its power, which is what I want.
<Guest4494>
But the BBB may decide it needs to switch back to the battery because it needs to shut the power supply down. If I use i2cset to disable the barrel connector power, it causes the BBB to shutdown, even though 'i2cget -f -y 0 0x24 0x0a' shows power is present on both the USB and barrel connectors.
<Guest4494>
Is there a way to force the BBB to switch back to the USB power without triggering a shutdown or reboot?

Hmm. The problem may be with my battery. Never mind.

AKN: you probably just missed some settings in your kernel config?
<zmatt>
my suggestion for customizing the kernel would be to use rcn's build scripts used to build the offical beagleboard.org kernels, and then just apply your customizations on top
<zmatt>
for the bbai you'll want to use the https://github.com/RobertCNelson/ti-linux-kernel-dev/ repo and then e.g. the ti-linux-5.10.y branch or the ti-linux-4.19.y branch depending on what major kernel series you want to use
