Hello again,
I'm still trying to return a value from "arm946e cp15" command to the
calling script.
I was not able to identify code patterns of return values
fromCOMMAND_HANDLER()
to the script engine.
The only method I found is to use .jim_handler instead of .handler
I'm ready to upload a patch to gerrit.
Is there anyone else who is interested in ARM9E architecture?
I guess to change the behavior of existing command, the other way
is to add new "arm946e_cp15" for example, command.
Which will be preferrable?
Regards,
Alex.
