Hi everyone,
I'm working on a wandboard with an i.MX6DL, and I found mentions in the documentation of a bridge between the APB and the AHB bus.
Since the DAP also uses the APB to debug the cores, I was wondering whether this bridge could offer debug capability from within the cores themselves, or whether there's any way we could debug one core from another.
Thanks
Jean
Hi Jean
There is some Coresight support in the kernel :
Linux/Documentation/trace/coresight.txt - Linux Cross Reference - Free Electrons
It doesn't use all the debug capabilities but might be interesting
to take a look in case you haven't seen it earlier.
Hope this helps
Regards
