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.

It's basically impossible to diagnose further without a serial cable like I 
described above. But you can keep feeling blindly and might get lucky. I have 
no idea what the led indicates, but it changed something.

 

Good luck!

Ok so I followed the guide and made some progress. 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?

Hello, I am currently working on a project based on the pocket beagle. 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.
