Dear Sir,
I have two board of BBB, the same SW, one is OK, but the other one can not power on.
When I insert USB cable to power on, the power LED D1, light on about 1 second, then power off.
we test the output of the TPS65217C, find everything is OK, the pin 9 PMIC_PWER_EN is off.
when I remove Y1, then D1 is light on.What is the cause of the phenomemon?
Please help us and give some hints for the problem.
