CE6 EBOOT and AISGen?

Other Parts Discussed in Thread: OMAP-L138

Hello all--
Has anyone tried this?
I've got OMAP-L138 2.1, with DDR2 (not mDDR) on a custom assembly.
We've been using SFH with the canned UBLs for devt and the modules with mDDR,
and going per the Quickstart guide with putting the UBL and EBOOT into SPI1 Flash.

I'd like to just AISGen the default EBOOT binary, and use SFH (or CCS5 and SPIWriter_ARM)
to put the image in the serial flash.

Any issues to expect with this? 
Does EBOOT do any PSC / PLL / DDR configuring after the UBLs are done?

Thanks! -- Joe

    Hi Joe,

    as far as i know Ebot doesn't modify either ddr or pll settings.

    But my suggestion is read eboot source code.

    regards,

    Thanks gsr--
    It appears you're right: EBOOT expects mem and PLLs to be in place before it starts messing with PINMUX.

    It does look like EBOOT checks for bootargs in the header from the UBL, but can use a default set
    if it finds bad/missing header. -- EDIT-- No, it doesn't.  I'm Mixing up my BOOT_ARGs.

    To the general audience of Gurus as well:
    One thing that would help is if 64MB and 128MB DDR2 UBL binaries were available.
    Not that I mind studying the build process of SFH, and modifying SFT and UBLs, but this is a steep climb.

    Thanks! -- Joe

     

    --EDIT--

    PS:
    Note that BSP 1.00.10  is suited to the LogicPD SOM:  The EBOOT menu option to set MAC is removed,
    and EBOOT expects an I2C EEPROM to provide ENET MAC.
    BSP 1.00.02 provides menu option to enter MAC, and store it in flash.

    PPS: 
    To others curious about rebuilding EBOOT:  if you try executing a Debug build, you will get Data Aborts
    in the iniitialized-data copy routine. 
    Yes, using Release build only is in the documentation, and not just for amusement.
