Today I worked with my BBB on 5V supply and everythings works fine. Then I
did connect an Lipo battery to the TP5/TP6 and TP8 and a 10Kohm between TP7
My idea was to research how the charger of the PMIC works, I connected an
5V supply for about 1.5A and everythin works fine, the battery charges
correctly and when the supply is disconnected it works ok.
After a while I disconnected the battery and connected the supply of 5V
again, but now the power LED flashes up, about 1 second off and 100 a
250msec on. It seems the PMIC is not starting, what is strange because
earlier it works fine.
When I connect the battery again and put on the 5V supply everything works
normal, the battery is going to charge and BBB is starting up.
Does somebody has an idea why the BBB wont work anymore with only the
Thanks in advance
