I am having an issue. I have successfully been able boot from eMMC. I have also configured the dip switch to use OFF ON ON OFF OFF so the boot media would be eMMC. I have been able to bring up the machine on ubuntu (using serial comm and putty on my desktop) and install tools I wanted. and perform normal task I wanted from the console. The problem I am having is when I disconnect the serial connection (micro usb cable) from the board and reboot it, it goes directly into uboot mode and gets stuck in uboot. To get the system out of uboot I have to re-connect the micro usb cable and reboot using putty terminal (from my desktop). Why does the system get into uboot automatically if there serial connection is not connected? is there anything I can configure from uboot mode to avoid this from happening?
here are my environment variables:
