Two possibilities that I can think of. #1 somehow your Linux image became corrupt, and "aborts" early in the boot process. #2 The processor is somehow damaged.
Usually the board will flash a USR LED or 4, but this is not always the case - when you have a bad Linux image, or boot loader. Additionally, if you gave us a schematic to look at or very minimum give a detailed bom + description of how things are connected . . . someone should be able to tell you what went wrong. If the processor in fact went south.
