Re: [beagleboard] Watching boot without HDMI
I can recommend the USB to TTL serial cable from adafruit: http://www.adafruit.com/products/954 It's inexpensive and I'm using it with my BBB. I know it says it's for Raspberry Pi but it's actually universal and works with both. On Thursday, March 6, 2014 11:42:00 AM UTC-5, Brad Hopper wrote: Great, thanks guys, truly a newb question.

Just to share, I have and use this one($20) which provides all 6 lines on a single 1x6 header and plugs directly into J1(black wire to J1-1) and it's used for Arduino(DC Boarduino). http://www.adafruit.com/products/70 -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Watching boot without HDMI
Folks, It seems to take a while for the BBB to boot. I'm going to check out the newly posted Debian image soon, but also wanted to know if there's any way to watch the boot in a terminal i.e. without using HDMI. I don't have a micro HDMI cable and was hoping not to get one. Is there a type of terminal connection which will persist through a reboot, so that the boot sequence could be seen? Not even sure if there's anything to see, just suspected that the boot sequence spends some time waiting on xyz... where xyz is probably something I don't need. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Watching boot without HDMI
Yes. It is called the debug port.

A TTL to USB cable will probably be most appropriate for you. -- Jack Mitchell (j...@embed.me.uk) Embedded Systems Engineer Cambridgeshire, UK http://www.embed.me.uk -- -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Stick a usb-serial adapter on J1 and watch the full boot process, plus the terminal is enabled, so you can use it once it boots.
