Yes, try some other power supplies. and if they stay between 4.75 and 5.25 under all the different load conditions a BBB can create, it will work fine.
USB power is highly variable from computer to computer. Sometimes it works fine, sometimes it does not. USB-1 was 0.5 Amps max, not enough to run a BBB, while booting or updating the eMMC. USB-2 is 0.9 Amps, about enough to handle the peak current from a BBB. The Voltage limits for USB are 4.5 to 5.5 Volts. No margin if at the limits under full load. --- Graham == On Wed, Nov 8, 2017 at 12:35 PM, <pekkajrouv...@gmail.com> wrote: > thanks for the answer. i think i need to find other power and test with > that.
