Hi,
I have made Analog / Digital IO ( ADC, DAC, OPTO and Relay) Device
drivers for MVME162-512 VME CPU Board using RTEMS 4.10.2 on Windows with
MinGW-get-inst-20110802 and RTEMS4.10 tools
Before integrating ADC / DAC Drivers, I have successfully configured,
build and run all sample and test applications on my CPU board.
Now I have added ADC/DAC Device Drivers for Four IO boards i.e ADC, DAC,
RELAY and OPTO. I have integrated Device Driver files in following steps :
1. First created a new folder ADCDAC in
..\rtems-4.10.2\c\src\lib\libbsp\m68k\mvme162
And added following Files
ADC.c
DAC.c
OPTO.c
RELAY.c
in ..\rtems-4.10.2\c\src\lib\libbsp\m68k\mvme162\ADCDAC directory.
2. Then modify makefile.am in ..\rtems-4.10.2\c\src\lib\ libbsp\ m68k\
mvme162
With
# ADCDAC
libbsp_a_SOURCES += adcdac/adcdrv.c adcdac/dacdrv.c adcdac/optodrv.c \
adcdac/relaydrv.c
to include ADC/DAC C files in makefile.
3. Then added Header files adc.h, dac.h, opto.h and realy.h
In ..\rtems-4.10.2\c\src\lib\libbsp\m68k\mvme162\include
And modify makefile.am in ..\rtems-4.10.2\c\src\lib\ libbsp\ m68k\
mvme162
With
include_bspdir = $(includedir)/bsp
dist_project_lib_DATA = bsp_specs
include/adc.h include/dac.h include/opto.h include/relay.h
The modified makefile.am in ..\rtems-4.10.2\c\src\lib\libbsp\m68k\mvme162
is :

4. I have included Header files in Drivers C Files (ADC.c, DAC.c etc)
With
#include <ADC.h> [ in adc.c ]
#include <DAC.h> [ in dac.c ]
#include <OPTO.h> [ in opto.c ]
#include <RELAY.h> [ in relay.c ]
Also modified ..\RTEMS\rtems-4.10.2\cpukit\sapi\include\condefs.h
To include ADC /DAC Device Driver Header files and Driver Table entries
just
(like CONSOLE AND CLOCK DRIVER TABLE ENTRY points :
/* Default Device Driver Table. Each driver needed by the test is
explicitly
* choosen by that test. There is always a null driver entry.
*/
The relevant part of this condefs.h file is as given below :
#define NULL_DRIVER_TABLE_ENTRY \
{ NULL, NULL, NULL, NULL, NULL, NULL }
#ifdef CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER
#include <rtems/console.h>
#endif
.
.
.
/******** ADDED BY MEDHAVI ***********************************/
#ifdef CONFIGURE_APPLICATION_NEEDS_ADC_DRIVER
#include <adc.h>
#endif
#ifdef CONFIGURE_APPLICATION_NEEDS_DAC_DRIVER
#include <dac.h>
#endif
#ifdef CONFIGURE_APPLICATION_NEEDS_OPTO_DRIVER
#include <opto.h>
#endif
#ifdef CONFIGURE_APPLICATION_NEEDS_RELAY_DRIVER
#include <relay.h>
#endif

#ifdef CONFIGURE_APPLICATION_NEEDS_IDE_DRIVER
/* the ide driver needs the ATA driver */
#ifndef CONFIGURE_APPLICATION_NEEDS_ATA_DRIVER
#define CONFIGURE_APPLICATION_NEEDS_ATA_DRIVER
#endif
#include <libchip/ide_ctrl.h>
#endif
And
#ifdef CONFIGURE_INIT
rtems_driver_address_table Device_drivers[] = {
#ifdef CONFIGURE_BSP_PREREQUISITE_DRIVERS
CONFIGURE_BSP_PREREQUISITE_DRIVERS,
#endif
#ifdef CONFIGURE_APPLICATION_PREREQUISITE_DRIVERS

#ifdef CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER

/*----- BEGINING : ADDED BY MEDHAVI ----------*/
#ifdef CONFIGURE_APPLICATION_NEEDS_ADC_DRIVER

#endif
#ifdef CONFIGURE_APPLICATION_NEEDS_DAC_DRIVER

#endif
#ifdef CONFIGURE_APPLICATION_NEEDS_OPTO_DRIVER

#endif
#ifdef CONFIGURE_APPLICATION_NEEDS_RELAY_DRIVER

#endif
/*----- END : ADDED BY MEDHAVI --------------*/
#ifdef CONFIGURE_APPLICATION_EXTRA_DRIVERS

#endif
#ifdef CONFIGURE_APPLICATION_NEEDS_NULL_DRIVER

#elif !defined(CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER) && \
!defined(CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER) && \

!defined(CONFIGURE_APPLICATION_NEEDS_FRAME_BUFFER_DRIVER) && \

#endif
};
#endif
5. Then I have defined following in samples\hello\init.c :
#define CONFIGURE_APPLICATION_NEEDS_ADC_DRIVER
#define CONFIGURE_APPLICATION_NEEDS_DAC_DRIVER
#define CONFIGURE_APPLICATION_NEEDS_OPTO_DRIVER
#define CONFIGURE_APPLICATION_NEEDS_RELAY_DRIVER
just to include ADC /DAC Header files and
6. Then after running configuration with following options :
When I run “make – w all”,I have observed following ERRORs in
..\rtems-4.10.2\
Testsuites\samples\hello\init.c
I. ../../../../../mvme162/lib/include/rtems/confdefs.h Error : adc.h
: No
such file or directory
“
II. ../../../../../mvme162/lib/include/rtems/confdefs.h Error : dac.h
:No
such file or directory
III. ../../../../../mvme162/lib/include/rtems/confdefs.h Error : opto.h :
No such file or directory
IV. ../../../../../mvme162/lib/include/rtems/confdefs.h Error : relay.h :
:No such file or directory
I have also found that makmefile.in and preinstall.am
..\rtems-4.10.2\c\src\lib\libbsp\ m68k\mvme162
Have not been updated though I have modified makefile.am (in same
m68k]mvme162).
My drivers source files like adcdrv.c and adc.h are not appearing in
makefile.in
Though I have included ADC / DAC Device Driver C and Header files and
included
these in relevant makefile.am just like CONSOLE and CLOCK Driver, I am
not sure why
header files like adc.h are not included in makefile.in
I have following queries regarding this problem :
1.why makmefile.in and preinstall.am are not updating (by generating
automatically by automake) as per modifications done in makefile.am
I believe that makefile.in and preinstall.am have to be automatically
get modified once we build RTEMS with modified makefile.am
2. What to do to get modified makefile.in and preinstall.am
3. Whether I have to modify some other makefiles / configuration files
Kindly provide your suggestions and solution to resolve the problem at the
earliest.
Further The Prototype Application for Testing ADC / DAC driver on
MVME162-522A is ready for Integration with RTEMS-4.10.2 and then testing
ADC/DAC Device Driver.
