C6748 EMAC Boot

Other Parts Discussed in Thread: OMAPL138

Is there an EMAC boot capability for the C6748 (or the SOM from Logic PD)?

If so, where is the documentation and any support packages for it?

Is there an implementation of U-Boot for the C6748 SOM?

    C6748 device does not support EMAC boot mode.The supported boot modes are listed in the Bootloader Appnote here

    uboot is implemented/offered on our ARM+DSP based devices alone, OMAPL138 which is from the same product family as C6748 , has uboot support. Why do you need uboot on c6748? If it is do initialize the device PLL, external memory , clock enabling (PSC etcc) similar to what ubl would do, you can do this via the AISGEN tools, also described in the boot loader appnote

    Hi Mukul,

    We do not need uboot specifically, anything that will act as a boot loader and support emac, will do.

    We need to boot the SOM by loading an image over ethernet, from a linux host (connected by cross-over cable).   We could run a tftp server in the linux machine, or similar if needed, and then go to raw ethernet for operation.

    We need to use ethernet because the configuration does not provide enough host uarts for the number of dsp's.

    Regards,
