The solution for such serial usb connector problem as mentioned in the previous post is just buy another cable and try your luck again. So I bought a “ch 340″ serial usb cable and connected the cable to computer and hawkboard again. Open the gtkterm and set the serial port communication parameters as done in the previous post. Power on the hawkboard. We can see the uboot prompt “hawkboard>” after some initial messages.

Now the situvation is that there is no pre installed linux (ramdisk) written in Nand memory of the board or there is no linux in memory card to boot into. The hawkboard> prompt is the uboot prompt where you can set values for various kernel boot arguments before issuing the boot command to boot into the linux.
