While working with Beagleboard-xm, It got hanged while booting.
After powering it again and after pressing reset button, no output is seen on console.
It won’t make any difference with and without mmc. Only LED D5 and D14 is glowing.
LED’s D7 and D6 which are near microSD wont glow.
Remove the SD card and power on. If you can’t see something like “60” (Not sure about Rev A3. For Rev B, it works) on minicom, there is something wrong with your host serial port/configuration. Meantime, if you have a signal tracer, see what comes out of the beagleboard serial port.
