Hi. I am having trouble using the GPS on the APF27 Wireless (APW)
module with the APF27Dev.

# /etc/init.d/S50gpsd start
Starting gpsd: OK
# cgps
Segmentation fault
#

I followed the instructions on:
http://www.armadeus.com/wiki/index.php?title=GPS_daemon
and
http://www.armadeus.com/wiki/index.php?title=GPS

but I can't see NMEA frames:

# stty -F /dev/ttySMX4 raw -echo -echoe -echok 38400
# cat /dev/ttySMX4

# gpsd -N -n -D 2 /dev/ttySMX4

Jumper j3 is on.

What else can it be?

Context:
The first edition of the mini workshop "Embed With Linux!" (EWiLi'11) is a
joint event that will take place during the RenPar/SympA/CFSE
(www.renpar.org) conferences.
The workshop lasts half a day and is integrated to SympA and CFSE
conferences programs.

Workshop Presentation:
During the few last years, the Linux operating system has progressively been
positioned as a strong alternative to proprietary and/or commercial
solutions in the embedded domain, whether it is deeply embedded (for
instance behind a virtual machine) or not, for application domains such as
multimedia (set top boxes), telephony, transports, etc.
The purpose of this workshop is to present research work, experimentations,
significant and original realizations that lie upon the implementation of an
embedded Linux in both academic and industrial projects.
This workshop also intends to be a meeting place for both industrial and
academic partners.
The expected contributions include but are not limited to the following
topics:
                - Embedded Linux and education
                - Embedded Linux and reconfigurable architectures
                - Linux and MPSOC
                - Methods, software and tool chains
                - Data management and memory hierarchy optimization
                - Real time, scheduling and temporal performance
                - File systems and I/Os in embedded Linux
                - Energy and power optimization in embedded Linux
                - Debug and profiling
                - Case studies and application projects
                - Performance evaluation and optimization

Invited Keynote :
Dr. John Williams of the university of Queensland (Brisbane) and founder of
Petalogix (Petalinux: first Linux solution for Microblaze softcore on FPGAs)
is invited to give a keynote on Embedded Linux and reconfigurable
architectures.

Submissions:
Papers should not exceed 6 pages and can be written in French or in English.
They should follow the formatting instructions that will soon be provided on
the web site: http://renpar.irisa.fr/satellite_eng.htm  

Submission can be made on:
https://www.easychair.org/conferences/?conf=sympa2011  . 

Authors should specify that submission is for the EWiLi workshop.

A selection of some papers will be proposed for submission in the "Open
Silicium" (open silicon) magazine, the French magazine of open source for
embedded systems (éditions Diamond).

Ideally I 'd like to use the SAHARA module but I'll just begin trying to
figure out how these drivers are coded.

Thanks for the information,

Hi,

I'm trying to catch the signal SIGXCPU, in order to know when a task goes in
secondary mode.
I would like to know, why I have to comment the fonction mlockall.

PS : The problem is not related to the Code, but, there is a piece of it :

#include "config.h"
#include <native/task.h>
#include <stdio.h>
#include <assert.h>
#include <signal.h>


void WorkingTask (void* cookie)
{
   while (1) {};
}

static RT_TASK Rt_Work_Task;

void go (void * cookie)
{
   printf("Test for switch : %d\r\n",(int)rt_task_self());
}

  void warn_upon_switch(int sig __attribute__((unused)))
{
   printf("/!\\ Secondary Mode /!\\ : ");
}

int main (void)
{
   RT_TASK Rt_main_task;
   int erreur;

   /* Pagination Locked */
  // mlockall( MCL_CURRENT | MCL_FUTURE );   <- This is the line which makes
my question


    signal(SIGXCPU, warn_upon_switch);

    /* Real-Time Task */
    rt_task_spawn (&Rt_main_task, "go", 2048, 20, T_FPU | T_JOINABLE,
&go,&Rt_main_task);

    /* Waiting for the end */
    rt_task_join(&Rt_main_task);

    return 0;
}

Charles

Hello,

i don't see 'pps_defconfig' any more ?
Previously i was using 'git clone' then 'make pps_defconfig' to try but no
more pps_defconfig :(

see you,

How may I configure the firmware ??

OK, you mean they SHOULD be relevant, but that's up to the module to do something correct... I will see what I get if I can have the 2nd dongle working someday.

Hi.

I am building a buildroot for the APF27, and it looks like fpga27regs is
built but fpgaregs is installed instead:

% find . -name fpga'*'regs -type f -ls
2006932    8 -rwx------   1 sam      sam          6848 Jan 18 11:04
./build_armv5te/fpgaregs-1.0/fpgaregs
2006933    8 -rwx------   1 sam      sam          6848 Jan 18 11:04
./build_armv5te/fpgaregs-1.0/fpga27regs
1820869    4 -rwxr-xr-x   1 sam      sam          3306 Jan 18 11:04
./project_build_armv5te/apf27/root/usr/bin/fpgaregs

Shouldn't fpga27regs be installed instead of fpgaregs? Could it be that
BR2_TARGET_ARMADEUS_APF27 is not defined at "make install" time, which would
lead to the build+installation of fpgaregs instead of installing the
previously built fpga27regs?

Toolchain is from today's git.

Thanks for the report !
It should be corrected now (board selection has changed).

Regards,
Julien

Found another problem but I have the fix. :)

simplegpio + button did not work together. When I load the modules I
get the error: "can't get major 250" on board_button or
board_simplegpio module. Just on the last module that is loaded.

I have attached the patch.
