(toppers-users 3547) Issues on SafeG/NT-/T-ASP/IDEA6410 execution

[Roman Kochanek]

Hello,

I just started to investigate the SafeG/ASP Project Implementation as a
starting point for another project that
I am working on. So I managed to figure out how to use the different
Cross-Development-Toolchains
as well as to compile different source codes like u-boot, safeg etc. for
the IDEA6410 platform on my own.
Therefore I used the guide which is provided in
"safeg-0.2-10jun2011-src". The result is that compiling is
fine but the execution does not work properly. To emphasize the problem,
I modified the output
values on the console in order to distinguish between the trusted ASP
and the non-trusted ASP.
As far as I understand the execution, firstly Safe_G initializes the
hardware layer and after that starts the
trusted ASP. In the trusted ASP two different tasks are defined and
executed whereas the one w/ a low priority
jumps towards the non-secure world by means of SafeG and starts the
non-trusted ASP executable. And here the
problem occurs so far. On both OS run times, a cyclic task is defined
which will be executed like the name already
says cyclically. But only on the trusted ASP. The attached log shows
that the MAIN task on both sides will be
deployed properly but the cyclic task is only executed on the trusted
ASP. What is the reason for this misbehavior?

NT-ASP:

INCLUDE("target_timer.cfg");

#include "sample1.h"

CRE_CYC(CYCHDR1, { TA_NULL, 0, cyclic_handler, 1000, 0 });
CRE_TSK(MAIN_TASK, { TA_ACT, 0, main_task, MAIN_PRIORITY, STACK_SIZE,
NULL });

T-ASP:

INCLUDE("target_timer.cfg");
INCLUDE("syssvc/syslog.cfg");
INCLUDE("syssvc/banner.cfg");
INCLUDE("syssvc/serial.cfg");
INCLUDE("syssvc/logtask.cfg");

#include "sample1.h"
CRE_TSK(TASK1, { TA_NULL, 1, task, HIGH_PRIORITY, STACK_SIZE, NULL });
CRE_TSK(BTASK, { TA_ACT, 2, btask, LOW_PRIORITY, STACK_SIZE, NULL });
CRE_CYC(CYCHDR1, { TA_NULL, 0, cyclic_handler, 4000, 0 });
CRE_TSK(MAIN_TASK, { TA_ACT, 0, main_task, MAIN_PRIORITY, STACK_SIZE,
NULL });

DEF_EXC(EXCH_NO_UNDEF, { TA_NULL, default_exch_undef });
DEF_EXC(EXCH_NO_SWI, { TA_NULL, default_exch_swi });
DEF_EXC(EXCH_NO_PABORT, { TA_NULL, default_exch_pabort });
DEF_EXC(EXCH_NO_DABORT, { TA_NULL, default_exch_dabort });
