I would say start the debug session and have it run until you need to
investigate things. You could even
use  'mspdebug' for that.

Re: [Mspgcc-users] Mspgcc-users Digest, Vol 120, Issue 3

2017-11-29 Thread Kees Schoenmakers

Hi,

I don't have the latest MSP FET model (black) but the older grey
version MSP-FET430UIF.

I learned the hard way that it may pay-off to save the i2c eeprom
contents upfront too.
I used Ponyprog2000 with a simple LPT port adapter to access the I2C
bus to the eeprom.
Furthermore use mspdebug -bsl to save the current contents of the FET
firmware for later use. Verify that you got all, don't forget the info
memory.
Now I have 2 versions around, one with the V2 version and one with V3
that understands tilib.

best regards,

Kees

[Mspgcc-users] buildscript for mspgcc-4.7.0

2014-12-17 Thread Kees Schoenmakers

Hi Friends,

Here my script. I had to workaround for some problems, most notably
for makeinfo.

When trying to build mspgcc with the host 4.8.2 compiler I ran into an
ICE too. But as
I have some older versions around I tried one and that let it build
successfully.

I hope it is useful for somebody.

best regards

Kees

Hello Friends,

I have a shellscript from the past that I used to build my mspgcc tools. I am
testing it now if it still works.

It builds mspgcc 4.7.0, msp binutils, mspgdb and the libraries.

I will post it if the results are good. I'am running Ubuntu 14.04  LTS
for some time.

[Mspgcc-users] code size

2014-12-12 Thread Kees Schoenmakers

I tried the newer msp-GCC (TI/RedHat) distribution on my project(s).

It still builds with _far_ more code then my present msp430-gcc
(4.7.0). This compiler
has also some minor habits but produces compact code.

So for the moment I will not switch to the newer version, my project
would not fit in the flash.

best regards,

Kees

[Mspgcc-users] no .infomem for msp430f449 ???

2014-09-25 Thread Kees Schoenmakers

Hello all,

Our project makes extensive use of infomem and even more 'infomem'
pages taken from the code space.

The first botch is that the linker script does not specify .infomem at all

error: no memory region specified for loadable section `.infomem'
collect2: error: ld returned 1 exit status


My question is:
is it possible to use a 'local' copy of the link script, modify it and
reference it in the Makefile?
And how should this local copy be referenced correctly to override the
system default?

[Mspgcc-users] default interrupt vectors

2014-09-25 Thread Kees Schoenmakers

Hi All,

I liked the way (old) mspgcc did preload all interrupt vectors with
UNEXPECTED(). That way it was easy to catch wrong interrupt
operations/assignments during debugging and also during normal
operation.

However this is not supported any more with the new toolkit.

[Mspgcc-users] code size

2014-09-25 Thread Kees Schoenmakers

Hello All,

I have a project that build fine with the 'old' mspgcc (4.7.0). I
managed to get it build and linked with the new toolkit. At first the
code did not fit, where it did before.

I disabled some features in the source tree and now I can build with
both GCC versions (4.7.0 vs 4.9.1). However the difference in code
size is significant, se the following comparison:

mspgcc   4.7.0   .text sizes

Main.o 0x184
Timers.o   0x226
Subroutine.o   0x21e
Eerom.o0x51c
Modbusmaster.o 0x1fa
Hartserial.o   0x422
Hartprocess.o  0x8ae
Hartunivers.o  0xa60
Hartcompractice.o 0x1a52
Hartransmspec.o   0xbfe
Hartmain.o 0x81a
Harttimers.o   0xb4
Sensors.o  0x2ee
Modbuserial.o   0x11e
Hartconversion.o   0x348
Hartplatformdep.o 0x2d0
libs   0xe4c

etext=0x9664

mspgcc 4.9.1  .text sizes

Main.o 0x1f4
Timers.o   0x27e
Subroutine.o   0x30a
Eerom.o0x68a
Modbusmaster.o 0x22a
Hartserial.o   0x436
Hartprocess.o  0xc5c
Hartunivers.o  0xb30
Hartcompractice.o 0x1c98
Hartransmspec.o   0xdda
Hartmain.o 0xa24
Harttimers.o   0xc0
Sensors.o  0x452
Modbuserial.o  0x142
Hartconversion.o   0x3dc
Hartplatformdep.o 0x32c
libs   0x306c

etext= 0xc906

I hope someone can use these numbers. I compiled with the same
CCFLAGS, optimizing etc.

Hi All,

I have a software project that builds fine met mspgcc (4.7.0)

I installed the toolkit via the T.I. site, modified the Makefile to
reflect this compiler and support files, Trying to build gives a long
list of messages, Here I snipped from the top.

 By specifying -std=c99 you have disabled all the GNU extensions, including
 asm.

 Try --std=gnuc99 instead, or replace asm with __asm__ in those headers.

Thank you, I'll try.

2014-09-10 Thread Kees Schoenmakers

Hello All,

I found the archives for the newest msp430-gcc on the TI site via
.
http://www.ti.com/tool/MSP430-3P-GCC-MSPGCC-TPDE

I found that it installs by default in /opt/ti/gcc  which does not
interfere with my existing msp430-gcc toolchain. I also installed the
support files in /opt/ti/support

I modified my Makefile to refer to the new toolchain, includes and libs.

When doing a make I get a complaint about an Interrupt routine entry:

In file included from /opt/ti/support/include/msp430.h:367:0,
 from Mainapp.h:22,
 from Main.c:15:
Main.c: At top level:

 ^
Main.c:205:12: note: in expansion of macro 'PORT1_VECTOR'

make: *** [Main.o] Error 1

I tried various changes but no result. How to satisfy this error complaint?

Hello Ben,

Yes I downloaded them from

http://www.ti.com/tool/msp430-gcc-opensource

so they are the production version.

Thank you any way,

 The production version of GCC for MSP430, which TI announced* on August
 18,
 lives here:

   http://www.ti.com/tool/msp430-gcc-opensource

 ... whereas the URL you mentioned seems to refer to a beta release.

 I don't know whether the production version fixes the syntax error you saw,
 but
 perhaps it's worth a try.

 Hello!
 I've got an issue with using __delay_cycles() while also utilizing
 TimerA interrupts.
 It seems that __delay_cycles(); is not working if TimerA interrupts
 are enabled. Even if nothing is done in interrupt routine.
 Here is a sample code:
 == main.c 
 #include msp430g2553.h

 // Timer A0 interrupt service routine (at top value)
 #pragma vector=TIMER0_A0_VECTOR
 __interrupt void Timer_A0 (void) {
 TACCTL0 = ~(TAIFG); // clear interrupt  flag
 }

 // Timer A1 interrupt service routine (in the middle)
 #pragma vector=TIMER0_A1_VECTOR
 __interrupt void Timer_A1 (void) {
 if (TACCTL1  TAIFG) {
 TACCTL1 = ~(TAIFG); // clear interrupt  flag
 }
 }

 int main(void) {
 WDTCTL = WDTHOLD | WDTPW; //halt watchdog
 P1REN = ~(BIT6); // pull-ups are disabled on pins 0 and 6
 P1DIR |= BIT6; // pins 0 and 6 are outputs
 P1OUT = ~(BIT6); // pin 6 and pin 0 are LOW

 TACCR0 = 0x0fff; // set top value for timerA
 TACCR1 = 0x00ff; //set LED glow power
 TACCTL0 = (CCIE); // enable compare interrupt for TACCR0
 TACCTL1 = (CCIE); // enable compare interrupt for TACCR1
 TACTL = (TASSEL1 | MC0 | TACLR | TAIE); // SMCLK, cnt UP, clear,
 interrupt
 _BIS_SR(GIE); // enable blobal interrupts
 for (;;) {
 P1OUT ^= BIT6;
 __delay_cycles(100);
 }
 return 0;
 }
  end of main.c =

 I expect this code to blink with a LED on P1.6 with approximately 1
 second interval (no precise timing required). But all I see is the LED
 just lit all the time.
 If I comment out the line with _BIS_SR(GIE); the LED is blinking as
 expected.

 What could be the reason? My guess is interrupt routine is somehow
 spoiling registers used by __delay_cycles(). Is that true?
 Would be thankful for a workaround if there is such.

 I'm using msp430-gcc (GCC) 4.6.3 20120301 (mspgcc LTS 20120406
 unpatched) from Debian repository to build code for TI Launchpad
 MSP-EXP430G2 (M430G2553 chip).

 Thank you!

[Mspgcc-users] weird code with MSPGCC

2014-06-26 Thread Kees Schoenmakers

Hello,

I experienced some odd effect when msp430-gcc tries to inline  memcpy
and/or memset.

the code

#include stdint.h

void test_memcpy(void)
{
uint8_t mybuffer[10];
memset((uint8_t*)mybuffer, 0, 10);
}

when compiled with
msp430-gcc -c -O2 -mmcu=msp430f449 mspgcc_memcpy.c
results in

Disassembly of section .text:

 test_memcpy:
   0:   31 50 f6 ff add #-10,   r1  ;#0xfff6
   4:   81 43 06 00 mov #0, 6(r1)   ;r3 As==00, 0x0006(r1)
   8:   81 43 08 00 mov #0, 8(r1)   ;r3 As==00, 0x0008(r1)
   c:   31 50 0a 00 add #10,r1  ;#0x000a
  10:   30 41   ret

In my opion thats not clearing 10 bytes
Without optimation the code appears sound.

[Mspgcc-users] why mspgcc does ICE

2014-06-26 Thread Kees Schoenmakers

Hello,

The following piece of code cause an ICE to happen.

typedef struct {
unsigned long maskbits:20;
char extra;
} MYSTRUCT;

MYSTRUCT mys = {0};

void test_ice(void)
{
   unisgned  long lvar = 0x0f;

mys.maskbits = lvar;   // == ICE here
}

kees:$ msp430-gcc -mmcu=msp430f449 -c mspgcc_ice.c
mspgcc_ice.c: In function 'test_ice':
mspgcc_ice.c:13:15: internal compiler error: in convert_move, at expr.c:437

smaller bitfields work well. I don't know if later mspgcc versions
does ICE here too.

[Mspgcc-users] Bug in MSP430-AS

2014-03-24 Thread Kees Schoenmakers

Hello All,

I have a project which is build with IAR in the past and contains a
couple of assembly sources.
When building it with the lastest binutils(msp430-as) I am struck with
a bug in calculation of offsets. ALL versions of msp430-as, the latest
included, generate faulty code here.

I simplified one code sample to

intern1:mov #1,r15
   dec r14
   jz  lab1
   nop
   jmp lab2

intern2:dec r15
   jnz intern2
   ret

lab1:   mov #2,r14
  callintern1
  callintern2
  ret

lab2:   mov #3,r13
  ret
  .end

When I assemble it with
msp430-as -c bug430as.S

the resulting code shows weird offsets for the 'jumps' (jmp, jz jnz),
even the calls...

What is happening here?  In the final linked binary with a lot of .c
and .S files the offsets are also wrong in the same way.
Another project, solely of .c files runs well
