Other Parts Discussed in Thread: AM3715, DM3730

Hi all,

I am doing android porting on AM3715 processor. I referred  "TI-Android-GingerBread-2.3-DevKit-1.0_DeveloperGuide.pdf " for porting  and selected omap3_evm_config and omap3_evm_android_defconfig with respective x-loader, u-boot and  kernel build.After successes build I got the  x-load.bin in x-loader folder then i converted that into MLO ,u-boot.bin in u-boot folder and  "omap3evm" folder in the out folder.My question is now i am doing SD boot,shall i use this  MLO,u-boot.bin,uImage and filessystem on my development AM3715 board.I want know some other information like in TI documents saying  DM3730 and AM3715 are same,so shall i use DM3730 uImage on AM3715 processor.

Thanks & Regards

    The DM3730 and AM3715 are not the same.  They are pin-for-pin compatible devices, but the DM3730 is a superset device which includes a C64x+ DSP inside.  A MLO, u-boot.bin, uImage and filesystem appropriate for the AM3715 will run on the DM3730, because the AM3715 is a subset of the DM3730.

    Thank  you very much BrandonAzbell.

    I am trying to boot AM3715 processor board, In TI android porting document they given below command for AM37XX  that’s why I used these command and get MLO and u-boot.bin and kept in the SD card.For SD card boot I made pin configure like boot_sys[4-0]=10001 for mmc2 but my board is not getting any x-loader prompt

     

    To build x-loader

    Execute the following commands

    $ make CROSS_COMPILE=arm-eabi- distclean

    $ make CROSS_COMPILE=arm-eabi- omap3evm_config

    $ make CROSS_COMPILE=arm-eabi-

    This command will build the x-loader Image "x-load.bin"

    To create the MLO file used for booting from a MMC/SD card, sign the x-loader image using the signGP tool found

    in the Tools/signGP directory of the Devkit.

    $ ./signGP ./x-load.bin

    The signGP tool will create a .ift file, rename the x-load.bin.ift to MLO

    $ mv x-load.bin.ift MLO

     

    To build boot loader (u-boot)

    • Change directory to u-boot-omap3

    $ cd u-boot-omap3

    • Do the following to build u-boot for AM37x / DM3730 EVM

    $ make CROSS_COMPILE=arm-eabi- distclean

    $ make CROSS_COMPILE=arm-eabi- omap3_evm_config

    $ make CROSS_COMPILE=arm-eabi-

    This command will generate the u-boot Image "u-boot.bin"

    NOTE: Copy the "mkimage" from "tools" folder to ~/usr/bin folder on your host machine, this is needed for kernel
