Hi 

TI,

when will be the kernel ready for unlocking DCSM(f28388d) by command prompt in SCI serial interface (because we can't connect to jtag and ccs in the field for firmware update).

Thanks

    Harshit,

    Your question is essentially when we will have a F28388x SCI Flash Kernel. We are currently working on it. I don't have a specific date I can provide, but it should be in the near future.  I suppose you have looked at our App note sprabv4?

    Thanks,

    Sira

    Hi 

    Sira

    Could it be possible to run "serial flash prommer .exe " to unlock DCSM zones using command prompt without kernel project only by application project?

    Another way of asking the same question as follows: the "serial flash prommer .exe "  itself contains unlocking code or we need to write unlock code either in the main application project or in the Kernal project?

    Thanks 

    Harshit

    Harshit, not sure I understood your question correctly, I will answer based on how I interpreted your question.

    - the host sends a command along with Password to unlock the specific zone, and the target (code within the Flash kernel) has the logic to implement this unlocking feature using the provided information. So it cannot be done by the host itself. 

    - Possibly this feature can be moved into your application from the kernel.
