Hi Miroslav
It happens very often...
I tried create-sdcard.sh script to create SD card with my custom images.While i connect a charger with BBB, it starts booting and user LEDs were blinking.
I thing it happens when i connect the beaglebone black with UART debug cable(TTL-232R-3V3) towards PC means it stuck at uboot command prompt and also showing some junk characters.(not exactly)
Any suggestions????
Thanks
