C6472/TCI6486 EMAC boot

To whom might concern,

 

Does anyone have experience or example code for EMAC boot for C6472?

For me understanding from SPURA7D, EMAC boot require EMAC boot parameter table.

DSP EMAC will sent Ethernet-Ready announcement format packet to host processor.

host process should response EMAC boot table frame to boot-up DSP.

There are some question for this senerio:

  1. When I completed a DSP executable file "xxx.out" and transfered it to "xxx.hex" by c6xhex tool, how can I separate "xxx.hex" into EMAC boot table frame?
  2. How does EMAC boot table frame fill "xxx.hex" into DSP? I didn't see load address in EMAC boot table frame.
  3. Is there any code size limitation for DSP image by EMAC boot?

Does anyone can help this?

Thanks.
