AM263P4: Multi-core Project updates

Kunukuntla Geetha
Intellectual 410 points

Part Number: AM263P4

Hi,

In AM263P4, each core .out is formed and at the final .mcelf will be loaded into flash.

The SBL will take care of loading of firmware into the respective core based on the linker .cmd file. The information about which core is present and its address to be loaded will contain in NOTE SEGMENT.

But, if there is only one core's firmware say R51-0 to be updated(remaining fimware should not be disturbed). How do I do that? 

How do I flash independent software? 

I should generate certificate each mcelf file, but how would this be stored in flash? Like, seperate from previous entire(all cores included) mcelf file?

Regards,

Geetha

    This is not possible with mcelf, there is no incremental update provision as such supported.

    No as stated before this would not be possible, you will need to manually take care of it in your build process.
