[Gumstix-users] no boot after power problem

[Nghiem D. <nd...@uc...>]

Hello all:

 

While working with the 400mx connected to the breakout-gs, we used the USB
cable as well as a regulated 5V power supply connected to a LiPo battery,
not knowing that the breakout-gs was also being powered by the USB.  Long
story short, regulator heated up and now Gumstix will not boot.  Is it
fried?

 

On another note, reading the wiki gave us the impression that the
breakout-gs is NOT powered by USB by default, since it is written that a
ferrite bead needs to be soldered at FB2 in order to enable that.  That was
why we assumed that we needed to apply power.  Did anyone else get this
impression?

 

Regards,
