I connected my board in a router. I believe that this router wasn't working well, so, after this my UDOO stopped to work. The green light turn on but the red not. I flashed the SD car again but still not booting. Maybe my last option would be install a new bootloader. I really don't know what to do. Does someone have any idea what I could do to fix it?
You could connect the serial debug console and check the messages there. https://www.udoo.org/docs-neo/Basic_Setup/Serial_Debug_Console.html
