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 :

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>:
8314: f2 c0 40 00 bic.b #64, &0x0023 ;#0x0040
8318: 23 00
...
0000832a <vector_32>:
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!
