I strongly agree with Jim that the way for you to make progress is to connect up a serial cable. A FTDI FT232 USB to UART Converter is one easy way to do this. Only three wires (TX, RX and GND) from the pocket Beagle.
Once you have the serial output working, you could also try to boot something more simple off the SD CARD. You could try booting a simple app using TI starterware.

But you can keep feeling blindly and might get lucky. I have no idea what the led indicates, but it changed something. Good luck!

I hardcoded the device ID in u-boot so now when I boot all the user LEDs turn on momentarily but then turn off after one second. After they initially turn on they just turn off. Before hardcoding it, none of them turned on except the power LED. Does this mean that it is trying to boot but failed at some point? Also, one more thing I noticed is that when I plugged in the real Pocket-Beagle without a SD card Windows still recognized and allocated a COM port. However, when I plug in my version of the Pocket Beagle without the SD card, Windows doesn't recognize it. Could this be the issue?

For my project, I had an experienced friend design and fabricate a custom board based on the pocket beagle to suit my purpose using the schematics and files on Github, nearly everything is identical except for the following changes: Removed all GPIO pins (unnecessary space), and replaced the microUSB connector with a male USB 2.0 connector(so that the board could be directly connected to a computer without a cable. Everything else was untouched and I used the exact same parts as the Pocket Beagle. I am trying to boot it with the latest Pocket Beagle Debian image however unable to do so because of the hardware change(I'm assuming). This is my first time working with something like this (I'm a software guy) so I apologize if I have a lack of knowledge about some aspects with regards to hardware. What do I have to do to be able to boot the Pocket Beagle's Debian image on it? Originally I thought that because the hardware change was so minimal it should be able to boot the pocket beagle's images. However, I realized that there is probably gonna be problems with regards to hardware id and such. Thanks, and I would appreciate any help. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
