How to power up when power applied

Former Member
Former Member over 7 years ago

I have an embedded application in mind for the ultra96 board that requires booting automatically when power is first applied.  I believe in the 96boards specification (consumer boards, low cost, rev 1.0 2015 pg. 10) says that that boards should either have a switch that manually control power to them or boot automatically at first application of power if they are using a soft power switch.

I tried to find a way to power up and boot automatically in the user guide and by looking in the schematics but there didn't seem to be a way to do it.

In the schematic there are two 0 ohm resistors on the power_en line going to CTL4 input of the TPS6508641: R161 and R56.  Usually 0 ohms are there for config. purposes.

There's also an I2C interface to the TPS6508641 part.  Does the part have the ability to be configured over the I2C bus through the OS ?

Board power-up/boot when power is first applied is very common and necessary for embedded applications.  Hopefully there's a way to do this on the current boards and if not this feature will be added on the next revision if not.
