But in my foolish mind, I thought it would be some problem with the board that it is not booting into a linux. So I decided to do a Booting uboot over the UART (serial port). I turned off the power supply to the board and changed the position of DIP switch to 1-OFF,2-ON,3-OFF,4-ON.
Downloaded the UART Host Utility from http://www-s.ti.com/sc/techlit/sprab41.zip . unzipped the file in a Windows system. Installed the AISgen_d800k006_Install_v1.7.exe and now I have a UART Host utility available in Program Files\Texas Inst… Note that it is better to install the above tool in a Windows system with .NET framework installed (you can download it from http://www.microsoft.com/net/download.aspx ).
You need to have windows hyperterminal tool for serial port communication before you do anything like booting uboot over UART. Now you need to connect your serial to usb converter into the usb port of your windows running computer. Rigth click the my computer and take the Properties. Click the tab of Advanced Settings and click button “Device Manager”. Device Manger window will open now. click on the arrow left to COM devices, there you can see all the COM peripherals connected to your computer right now. You can also your serial to usb converter and associated COM PORT like COM 19 etc. Open the hyperterminal and go to File>Properties and select COM 19 and click on its properties button and change the Bits per Second to 115200, Data bits to 8, Parity to None, Stop bits to 1, and Flow Control to None. Now click OK.
Now connect the hawkboard to serial to usb converter and power on it. Click the Telephone button on the Hyperterminal and press enter button. you can see a message
BOOT ME.
then click on the telephone hang button(else UART host utility can’t acess the hawkboard).
Then I opened the Uart Host Utility loaded u-boot_uart_ais_v1.bin from http://code.google.com/p/hawkboard/downloads/list as ais file. Selected COM19 and baud rate as 115200. Clicked on the Start button. A lot of messages came in the window and finaly something like (Serial Port): Closing COM19. Then I looked into the hyerterminal and clicked on the telephone button and pressed enter again I saw a “hawkboard>” prompt. Now I thought the board got some serious issues and it is the reason for the above behaviour.
Later after a lot of googling, I found that the problem is that I didn’t put a kernel and root filesystem into to the board to boot it up.
