Hardware Details

• Technical Reference Manual for OMAP L 138 Processor is Here
• Applications of OMAP L 138 are Here

Software Details

Tools

• ARM Cross Compiler
• DSP Cross Compiler c674x via option -mv6740
• AIS Generator / UART Host Tool

Sources

• Linux Kernel
• u-boot

Building verification images from source

Compiling u-boot (bootloader)

1. Issue compile commands with make:

  make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- distclean
  make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- omapl_hawkboard_config 
  make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

Signing u-boot for UART boot

1. Copy u-boot (elf) file to the host machine where AIS Generator is installed. Follow the below steps
2. 
3. 
4. 
5. 

Signing u-boot for NAND boot

1. Copy u-boot (elf) file to the host machine where AIS Generator is installed. Follow the below steps
2. 
3. Configure PLL0, PLL1, DDR tabs as shown above. The File name to generate remains as in the step above.

Compiling Linux Kernel

1. Issue compile commands with make:

  make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- distclean
  make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- omapl138_hawkboard_defconfig
  make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage

Booting

Booting u-boot over UART

• Power OFF the board
• Close any previously running terminal programs
• Connect the UART cable to the Host machine.
• Configure the Boot Switches as 1-OFF 2-ON 3-OFF 4-ON
• Start the UART Host Utility, should have been installed with AIS Generator / UART Host Tool
• Select the AIS FILE Generated for UART
• Click on the Start button
• Power UP the Device
• If you see errors click on stop and press start again and give a board reset.
• Wait till you all the below messages and COM is closed:

  (File IO): Read 414964 bytes from file D:\hawk_release\u-boot_uart_ais.bin.
  (Serial Port): Opening COM1 at 115200 baud...

• Now Start any standard UART Terminal and hit enter key, should see the u-boot prompt

Procedure to flash u-boot on NAND

After booting the u-boot over UART as mentioned above,

• On the u-boot prompt in the terminal window
• Configure the Ethernet server and Client IP addresses

  hawkboard.org > setenv serverip 172.24.156.199
  hawkboard.org > setenv ipaddr 172.24.190.58</pre>

• Download the u-boot generated for NAND

  hawkboard.org > tftpboot 0xc0700000 u-boot_nand_ais.bin
  
  TFTP from server 172.24.156.199; our IP address is 172.24.190.58
  Filename 'u-boot_nand_ais.bin'.
  Load address: 0xc0700000
  Loading: #################################################################
           #################
  done
  Bytes transferred = 414988 (6550c hex)  

• Erase NAND Flash

  hawkboard.org > nand erase

  NAND erase: device 0 whole chip
  OK

• Flash the NAND with u-boot

  hawkboard.org > nand write.e 0xc0700000 0x20000 0x70000

  NAND write: device 0 offset 0x20000, size 0x70000
  458752 bytes written: OK

• Switch off the board
• Change the DIP Switches for NAND boot 1-ON 2-OFF 3-OFF 4-OFF

Booting u-boot over NAND

Flash u-boot into NAND as mentioned above

• Switch off the board
• Change the DIP Switches for NAND boot 1-ON 2-OFF 3-OFF 4-OFF
• Switch on the board

Booting Linux Kernel and Mounting RAMDISK

Booting Linux Kernel and Mounting NFS (Network File System)
