(toppers-users 3552) Re: Issues on SafeG/NT-/T-ASP/IDEA6410 execution

[Roman Kochanek]

Hey Daniel,

your proposed changes are working but have a "strange" side effect.
Depending on the length (number of chars) of the output the execution is
running properly or not. From my point of view it has something to do
with the scheduling of the RTOS on the secure world and switches between
the two worlds. Could you provide me some information about the
scheduling of the RTOS and especially how the "jump" is done from the
nt-rtos to the t-rtos? In the source code I only see the call inside the
btask towards the secure monitor/non-secure world. Could you also
explain the changes (idea6410nt.h) in more detail?
A further question is if you could provide a short instruction to run a
native linux kernel on the nt-side? The available instruction describes
patching the linux kernel but unfortunately the
safeg-linux-XXXXX-all.patch is not included for the IDEA 6410 board.
Using the provided patches in the idea 6410 folder, a large number of
errors occur while executing the patch on the android linux kernel sources.
