C6472 EMAC boot configuration table

Is it possible to sen a Boot Configuration Table when using the EMAC boot mode for C6472 (i.e. to conifgure DDR2)?

Based on the bootloader users guide, it seems like this is only possible from I2C boot mode.

Thanks,
David

    Hi David,

    In C6472 EMAC boot mode you can send only bootp packets and receive that packets only using ethirial softaware.

    Thanks.

    Naresh, thank you for your response.

    I was more curious to know if you can send a boot configuration table to the DSP using EMAC boot mode, similarly to how you can send a boot table (as described in section 4.3.5.3 of SPRUEC6G, the Bootlaoder User's Guide).

    You cannot send boot configuration table, but you can indded write your application that you sending from host to first goahead and configure DDR and then load the real image you want into the DDR and execute. If you don't want to go through the pain of writing the application, then I2C boot and EMAC secondary boot will be a good way to do it. And I would suggest to follow the route as it will be easy to implement.

     

    Thanks,

    Arun.
