ais_image.bin How and where to find this file for OMAP-L138 LCDK?

Other Parts Discussed in Thread: OMAP-L138, OMAPL138

Dear all,

I am a new hand and I am learning DSP programming for 0. This is my first project during study. My board is OMAP-L138 LCDK. I want to program it in the Windows system. I am following the "LCDK User Guide" ( http://processors.wiki.ti.com/index.php/LCDK_User_Guide)

In the Section Procedures NAND Flashing , serial port method,

sfh_OMAP-L138.exe -targettype OMAPL138_LCDK -flashtype NAND -p COMx -flash_noubl ais_image.bin

Run the commands and then power cycle or reset the board to initiate the process.

Result: failed

it seems that I do not have the ais_image.bin file.  Where or how can I get this file?

Thank you.

P.S.

Maybe I should first restore the default u-boot image? How should I do that?

In this link http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L138#Obtaining_the_software

A pre-built u-boot image is located in the images/u-boot/ directory of the PSP installation

But I can not find the u-boot image.

 

Thank you again.

    Hi Jinlong Shen,

    As per below link, You can get the U-Boot image in Linux SDK path.

    http://processors.wiki.ti.com/index.php/OMAP-L138_LCDK_Linux_Software_Developer%27s_Guide#OMAP-L138_LCDK_Related_Info_and_Activities

    You need to bring the u-boot image to the your Windows PC to use with this tool.
    The pre-built image of u-boot, u-boot-lcdk.bin, under <LCDK Linux install path/board-support/prebuilt_images,
    can be used to test out this procedure as well.

    And in command:

    As per link, http://processors.wiki.ti.com/index.php/LCDK_User_Guide#Debug

    You have to find out the Serial port in Host PC.

    In command,

    sfh_OMAP-L138.exe -targettype OMAPL138_LCDK -flashtype NAND -p COMx -flash_noubl ais_image.bin

    You need to specify the COM port number as -p COM5 For example, serial port is 5.

    1. Thanks, Baliji, in Order to move the u-boot image file u-boot-lcdk.bin from the Linux SDK to a Windows PC, I will have to have access to a linux PC, am I right?

    Or can I download it from the TI website?

    2. I understand that , the demo applications about face detection and fingerprint detection "will" be readily flashed on my NAND Flash memory. Am I right?

     

    3. Is there a step-by-step "Hello World"-style manual for just doing a "Walk through"? The two latest books about OMAP L138 Experiment Kit do not help me.

     

    Thank you.

    Sorry again, I would really appreciate it if someone here can help me out.

    I need to obtain u-boot-lcdk.bin.

    I am using Windows 7, CCSv5.2 and OMAP-L138 DSP ARM9 Development Kit (LCDK). I have found the ubl-OMAPL138_LCDK_NAND.bin. I am lacking the u-boot-ldck.bin.

    I have no access to Linux. Note: I was told here and also in guides that this file is in the SD Card for Linux.

    Thank yooooooooou!

    Hi Jinlong,

    To get the U-Boot image, you need to install the Linux SDK.

    Install the C6000 BIOS SDK to get the Face detection and fingerprint detection
    programs.
