My BBB is A5C version. We've tested more than 10 pcs BBB and all of it has the same problem... One, but not very elegant solution is to after start the board, make a jumper between pins SYS_5V and VDD_5V, in example with any mosfet transistor. With this jumper, on kernel 3.2 there was no reset from the time of three weeks. Anybody have any other solutons? Because this cannot be the final.
Best regards! I look forward for suggestions! Jakub. W dniu piątek, 8 listopada 2013 05:12:08 UTC+1 użytkownik Lei Wang napisał: > > I have the same problem with BBB running Android.
