Ok, I think that the bug is in msp430F47xx.h file.
All the vectors are defined with the vector base address (0xFFC0) ! It
is wrong ! the correct base address for the vectors is 0xFFE0 !
wrong definitions
#define BASICTIMER_VECTOR 32 /* 0xFFE0 Basic Timer / RTC */
#define PORT2_VECTOR 34 /* 0xFFE2 Port 2 */
#define USCIAB1TX_VECTOR 36 /* 0xFFE4 USCI A1/B1 Transmit */
#define USCIAB1RX_VECTOR 38 /* 0xFFE6 USCI A1/B1 Receive */
#define PORT1_VECTOR 40 /* 0xFFE8 Port 1 */
#define TIMER0_A1_VECTOR 42 /* 0xFFEA Timer A CC1-2, TA */
#define TIMER0_A0_VECTOR 44 /* 0xFFEC Timer A CC0 */
#define SD16_VECTOR 46 /* 0xFFEE ADC */
#define USCIAB0TX_VECTOR 48 /* 0xFFF0 USCI A0/B0 Transmit */
#define USCIAB0RX_VECTOR 50 /* 0xFFF2 USCI A0/B0 Receive */
#define WDT_VECTOR 52 /* 0xFFF4 Watchdog Timer */
#define COMPARATORA_VECTOR 54 /* 0xFFF6 Comparator A */
#define TIMER0_B1_VECTOR 56 /* 0xFFF8 Timer B CC1-2, TB */
#define TIMER0_B0_VECTOR 58 /* 0xFFFA Timer B CC0 */
#define NMI_VECTOR 60 /* 0xFFFC Non-maskable */
correct definitions
#define BASICTIMER_VECTOR 0 /* 0xFFE0 Basic Timer / RTC */
#define PORT2_VECTOR 2 /* 0xFFE2 Port 2 */
#define USCIAB1TX_VECTOR 4 /* 0xFFE4 USCI A1/B1 Transmit */
#define USCIAB1RX_VECTOR 6 /* 0xFFE6 USCI A1/B1 Receive */
#define PORT1_VECTOR 8 /* 0xFFE8 Port 1 */
#define TIMER0_A1_VECTOR 10 /* 0xFFEA Timer A CC1-2, TA */
#define TIMER0_A0_VECTOR 12 /* 0xFFEC Timer A CC0 */
#define SD16_VECTOR 14 /* 0xFFEE ADC */
#define USCIAB0TX_VECTOR 16 /* 0xFFF0 USCI A0/B0 Transmit */
#define USCIAB0RX_VECTOR 18 /* 0xFFF2 USCI A0/B0 Receive */
#define WDT_VECTOR 20 /* 0xFFF4 Watchdog Timer */
#define COMPARATORA_VECTOR 22 /* 0xFFF6 Comparator A */
#define TIMER0_B1_VECTOR 24 /* 0xFFF8 Timer B CC1-2, TB */

#define NMI_VECTOR 28 /* 0xFFFC Non-maskable */

Thanks, but I don't use -nostartfiles option !
I think that it is a bug, because if change the MCU (like F2274) there
is no problem!
Regards!
Wayne Uroda a écrit :
Are you compiling with the -nostartfiles flag? If so, you can define the
vectors yourself (maybe you need to, I am not sure...)
Make an array which is the size of your vectors, and initialise it manually
Something like
__attribute__ ((section(".vectors"))) unsigned short loadVectors[] = {(unsigned
short)&unexpected, (unsigned short)&unexpected, (unsigned short)&someISR, ... };
Make sure that it has the correct number of entries.
Apologies if this code is incorrect as I don't have mspgcc here to check. I use
something similar except my ISR routines are fixed stubs which branch to other
locations, so I am not sure if the &function will work correctly at
compile/link time.
If you are not using -nostartfiles, then sorry I don't think I can help!
Good luck!

Subject: [Mspgcc-users] Interrupt vectors are ignored with asm rountines
(MSP430F4783)
project with MSP430F4783
first problem solved here :
http://sourceforge.net/mailarchive/forum.php?thread_name=49BF8544.7090708%40ap3.fr&forum_name=mspgcc-users
Thanks 'Sergey A. Borshch'
In my projects, I use my own startup routine (in assembler) ! I use
several interrupts :
NMI_VECTOR, WDT_VECTOR, BASICTIMER_VECTOR, PORT1_VECTOR
but all of theses are ignored (see below) only _reset_vector__ is correct
00008008 <__ctors_end>:
8008: 30 40 0c 80 br #0x800c
0000800c <_unexpected_>:
800c: 00 13 reti
0000800e <_reset_vector__>:
800e: 31 40 ee 05 mov #1518, r1 ;#0x05ee
8012: d2 c3 31 00 bic.b #1, &0x0031 ;r3 As==01
8016: d2 d3 32 00 bis.b #1, &0x0032 ;r3 As==01
...
00008144 <vector_60>:
8144: d2 d3 32 00 bis.b #1, &0x0032 ;r3 As==01

00008314 <vector_40>:

832a: 00 13 reti
...
0000832c <vector_52>:
832c: 12 12 70 01 push &0x0170
part of HEX file :
*:10FFE00008800880088008800880088008800880D1*
*:10FFF00008800880088008800880088008800E80BB*
reset vector : good (0x800E) !
all others vectors are wrong : point to 0x8008 !!!
Thanks for reply!
