Hi PTG

We want to be able to load executable programs onto core B of a BF561 where we are running uClinux on core A. We want to initiate the loading from core A userland or application. I have seen there is the "corebld" utility mentioned in your documentation. Does this have support for loading any form of executable images generated by ADI's VDSP tools? Or is there any other such thing that would do that, which you support?

Thanks,

Hans

it should work provided VDSP creates a correct ELF

It sounds like it has not been tried?

It seems like this would be a good idea to support uClinux on core A loading VDSP type programs on core B. Is there any plans for the 2 teams to collaborate on this?

we havent heard anyone complain about coreb not working with VDSP.  it's pretty trivial for you to try it out and see if it works.

and again, the source of the ELF is irrelevant.  if the ELF is formatted correctly, then there shouldnt be any problems.  if VDSP is producing incorrect ELFs, then that is a bug to be reported to the VDSP team.  we are not them.

We don't test/support it - because there is little way to debug it.

Many times connecting the VDSP debugger/ICE to the system will kill the kernel on core A. We can't help with this.

We have also seen many times that the Core B (VDSP applications) causes problems in the system, and causes the kernel to crash. - this is almost impossible to debug at this stage in time.

Some people have gotten it to work - but they have done with without our help.
