Re: [beagleboard] power up using +5 volt jack

2014-05-02 Thread DLF 
Sounds like the explanation to me.   - thanks for that.

  I don't have the skills to rework the board so I'll just put up with 
it.  Not a huge issue for me.

cheers,

 is correct.

 To power on all you have to do is plug in the power, either USB or DC.

Re: [beagleboard] power up using +5 volt jack

2014-05-02 Thread Brandon I 
The beaglebone had a power up issue. Rev A6A fixed it:

>From the wiki
:  "Changed C24 to a 2.2uF capacitor. This extends the reset signal to 
solve an issue where some boards would not boot on power up."

I have around 40 beaglebones running and this was a pretty serious problem 
for us. Our users guides have a somewhat embarrassing "If the board doesn't 
boot, unplug the power and wait 10 seconds." I have around 20 Rev. B 
boards, and I haven't seen one fail to power up.

You could always rework the board yourself! :D

 Hi,

 now I am confused because I thought it was normal procedure to hold the 
 power button after inserting the 5V jack.   (as noted by Richard-tx)

 I always have to hold the power button after inserting the jack.  When 
 I insert the jack, I see a brief blue light from the pwr LED next to the 
 5V 
 connector and then nothing.  If I hold the power button it boots.  - every 
 time.

 This thread lead me to believe the power button was the right way to do 
 it !https://groups.google.com/forum/#!topic/beagleboard/FGeL6jzOcB0

 however the SRM indicates otherwise   :(

 7. Booting the Board
 As soon as the power is applied to the board, it will start the booting 
 up process.
 When the board starts to boot the LEDs will come on in sequence as 
 shown in Figure
 15 below. It will take a few seconds for the status LEDs to come on, so 
 be patient.
 The LEDs will be flashing in an erratic manner as it boots the Linux 
 kernel.


 It is not the end of the world for me, but just interested all the same.

 cheers,

[beagleboard] power up using +5 volt jack

2014-04-27 Thread Richard-tx 
The way my BBB works is like this:

To power up the BBB from OFF when powered from the 5 v jack, I have to 
press the power button.
To power up using the mini-usb connector, all I have to do is turn on the 
USB power.

My question is this.  Is there a way to have the BBB automatically power up 
when power is applied to the +5 jack?
