Re: [Mspgcc-users] (no subject)
Apparently there is material that must go into .rodata and .data (low memory) that exceeds the available space, causing it to overflow into .vectors. See other message earlier this week for suggestions of how to diagnose where things might be going wrong and how to rearrange things to fit.

Re: [Mspgcc-users] (no subject)
Everything's up on the mspgcc4 project. I use git to manage things. See http://mspgcc4.git.sourceforge.net/git/gitweb-index.cgi Baseline mspgcc4 is maintained in subversion by some folks in the EU; I have several patches submitted to them but don't muck with their repository until they've approved the changes. Nonetheless, I feel what's in git is pretty stable, and the subversion repository has most of what's needed. mspgcc4's git repository has a branch next that's always the most solid version I have available. mspgcc4 incorporates patches to a couple versions of binutils. There's a git repository in which those patches are maintained in branches, to make it easier to update them. msp430-libc is also hosted in a git repository on mspgcc4. The mspgcc4 git repository incorporates some spec files for building RPMs, based on your work in fact, but the project owners weren't thrilled about adding distribution-specific stuff. I think that's the best way to help get the latest version into various distributions, but haven't pursued it. I'd love to get debian build infrastructure as well, but haven't been able to get the equivalent to a spec file: debian tools seem to require a lot more pieces. The guy who builds them for Ubuntu has said he'll do it through his launchpad setup, but prefers to wait until the subversion repository is updated. For the OSHAN TinyOS environment that People Power distributes, I do a very crude approach based on checkinstall.

Re: [Mspgcc-users] (no subject)
I'm not exactly comfortable with building manually, but maybe it's high time to learn it properly get used to it. I will add ticket too. The deadline for my work is not yet exactly decided, but it will be around end of august/september, probably depending on how the project starts rolling. I don't know exactly what kind of promises my project leader has made though. So I'm personally interested in testing atleast, but I'm still quite a beginner. I am eager to learn new stuff too.

Hello, I am programming my MSP430F1611 with assembler using the msp430-toolchain on OpenSuse 10.3 and cannot get interrupt vector table set up in the µC. I have an OLIMEX dev board connected via JTAG, my application is supposed to blink a led on port P6.0 every second using the timerA0 CCR0 interrupt in up mode. After downloadingt the code to the µC using msp430-jtag, all interrupt vector addresses are set to 0x. The program works if I manually set interrupt vector addresses with the debugger. What is the problem In my assembler code (main.S) I set up section .vectors as this: .section .vectors .ORG DACDMA_VECTOR,0xFF .word DACDMA_VECTOR_ISR ; 0xFFE0 DAC12/DMA .org PORT2_VECTOR,0xFF .word PORT2_VECTOR_ISR ; 0xFFE2 Port 2 .org USART1TX_VECTOR,0xFF .word USART1TX_VECTOR_ISR ; 0xFFF4 USART 1 Transmit .org USART1RX_VECTOR,0xFF .word USART1RX_VECTOR_ISR ; 0xFFF6 USART 1 Receive .org PORT1_VECTOR,0xFF .word PORT1_VECTOR_ISR ; 0xFFE8 Port 1 .org TIMERA1_VECTOR,0xFF .word TIMERA1_ISR ; 0xFFEA Timer A CC1-2, TA .org TIMERA0_VECTOR,0xFF .word TIMERA0_ISR ; 0xFFEC Timer A CC0 .org ADC12_VECTOR,0xFF .word ADC12_VECTOR_ISR ; 0xFFEE ADC .org USART0TX_VECTOR,0xFF .word USART0TX_VECTOR_ISR ; 0xFFF0 USART 0 Transmit .org USART0RX_VECTOR,0xFF .word USART0RX_VECTOR_ISR ; 0xFFF2 USART 0 Receive I2C tx/rx .org WDT_VECTOR,0xFF .word WDT_VECTOR_ISR ; 0xFFF4 Watchdog Timer .org COMPARATORA_VECTOR,0xFF .word COMPARATORA_VECTOR_ISR ; 0xFFF6 Comparator A .org TIMERB1_VECTOR,0xFF .word TIMERB1_VECTOR_ISR ; 0xFFF8 Timer B CC1-2, TB .org TIMERB0_VECTOR,0xFF .word TIMERB0_ISR ; 0xFFFA TIMER B CC0 .org NMI_VECTOR,0xFF .word NMI_ISR ; 0xFFFC Non maskable .org RESET_VECTOR,0xFF .word RESET ; POR, external RST, Watchdog To compile I use the following commands: msp430-gcc -mmcu=msp430x1611 -o blink1s.elf main.o msp430-gcc -mmcu=msp430x1611 -nostartfiles -nostandartlibs -o blink1s.elf main.o Then I generate an assembler listing with: msp430-objdump -DS blink1s.elf blink1s.lst At the end of blink1s.lst I can find my interrupt vector table, which I believe is correct: Disassembly of section .vectors: ffe0 _vectors_end-0x20: ffe0: 52 40 interrupt service routine at 0x4052 ffe2: 58 40 interrupt service routine at 0x4058 ffe4: 5e 40 interrupt service routine at 0x405e ffe6: 64 40 interrupt service routine at 0x4064 ffe8: 6a 40 interrupt service routine at 0x406a ffea: 70 40 interrupt service routine at 0x4070 ffec: 76 40 interrupt service routine at 0x4076 ffee: 7a 40 interrupt service routine at 0x407a fff0: 80 40 interrupt service routine at 0x4080 fff2: 86 40 interrupt service routine at 0x4086 fff4: 8c 40 interrupt service routine at 0x408c fff6: 92 40 interrupt service routine at 0x4092 fff8: 98 40 interrupt service routine at 0x4098 fffa: 9c 40 interrupt service routine at 0x409c fffc: a0 40 interrupt service routine at 0x40a0 fffe: 00 40 interrupt service routine at 0x4000 I load the program into the µC with: msp430-jtag -e blink1s.elf --- no errors, but no blinking! Then I use ddd to debug with msp430-gdb over LPT1 (parport0): ddd --debugger msp430-gdb connect to the µC via JTAG and see the following: GNU DDD 3.3.11 (i386-suse-linux-gnu), by Dorothea Lütkehaus and Andreas Zeller.

Can the non-maskable interrupt (NMI) handler be located in the ROM? Yes. 3. Is it possible to use the DMA and the I2C bus within the NMI context?

Hi, Thanks for your answers. Just a couple of more follow up questions. 1. Can the BLS be user-programmed or is it default factory programmed? the BSL is hardwired but can be extended with code in RAM. That's the BSL update, which is an extension/patch. 2. Can any interrupt handler (DMA, I2C etc) be located in the ROM? The not ancient versions do have only RAM or Flash you can use. Because of the Von-Neumann-Architecture and linear addressing (and address space = I/O space) it doesn't matter where the code is. But the RAM gets cleared at power up reset. Regards, Rolf

Hi everyone, I am a new user of mspgcc and using msp430F1611. As compilation goes fine, debugging using Insight(GDB) is giving me problem of getting locked in whle loop waiting for timer flag set. The same program works fine for IAR Kick start. TI suggested to port their latest *.xcl,*. ddf and *.srf to gcc. Can anyone give me hints how i can update my gcc. Thanks in advance Sankar

Hi everyone, I am a new user of mspgcc compiler. we designed a board using msp430F1611. I successfully installed and compiled my program in windows XP machine. Now i got stuck in dubugging using Insight(GDB). While debugging, the debugger get locked at while loop requiring setting of timer (Both timer A and B) flag (TAIFG). It seems to me that debugger is indefinitely waiting for response from target and fails to have timer flag set. Now, the same program does work for TI demo board. So logically i suspect the problem is in our board. However, our board does also work, if you reset the board by terminating debugg session. I would apprecite it very much if you share with me if anyone of you have ever experienced such problem. thanks in advance Sankar
Re: [Mspgcc-users] (no subject)
Insight is not supported now. I suggest you to used Eclipse instead, it work perfectly with MSPGCC! A readme file posted on this group explain how to install it! --- Frederic Beaulieu, M.Sc.

RE: [Mspgcc-users] (no subject)
Hi Frederic, I have tried (sorry for my english) to work with eclipse and mspgcc for a long time and I have not obtain good results. Actually I can compile my msp430 programs, but when I try to debug (simulate or emulate) nothing works. And the problem is that I have not found any information about eclipse and mspgcc, a good tutorial about it. All I have is the eclipse info, but what I need is something like eclipse+mspgcc for stupids (I want to say for people who has no idea about it). Do you know where can I obtain this information? For example, what releases of eclipse, cdt and mspgcc must I install? Must I launch mspgcc-gdbproxy before start debugging? Whats the meaning of the error messages and what can I do to solve it? and this basic things. You have said that you have post a tutorial file to the list ... where can I find this? (I am new in the forum and I do not know where I must search this info) Finally I want to say that every time I try to debug an simply program (and I have configured as the eclipse help explains) I usually obtain next error: Info threads Warning: RMT ERROR: failed to get remote thread list Warning: Remote failure reply: E00. Thanks in advance, Jose Maria.
RE: [Mspgcc-users] (no subject)
There are a lot of discussion about this in this group and in Yahoo MSP430 group. Just search in them. We write a little readme file which can, may be, help you: 1- Install Eclipse - just copy directory into hard disk 2- Install cygwin(click cygwin setup.exe in eclipse folder) from the Internet with gcc(dlevel), gdb(dlevel), openssh(net), openssl(net), cvs(dlevel), tcsh(shell) and xinetd(net). The red hat and calgary servers worked for me. Red hat is faster. 3- Modify environmental variables(control panel, system, advanced): create: CYGWIN ntsec tty JAVA_HOME (Home java directory) add in PATH: C:\cygwin\bin %JAVA_HOME%\bin C:\cygwin\usr\X11R6\bin 4- Run net.sf.mspgcc.zip in Eclipse folder and extract files in Eclipse\plugins 5- Run Cygwin (you should only have to do this once) 6- Reboot the machine 7- Click eclipse.exe and create new project(file, new, project) 8- Select Standard Make C project, next, select a project name, finish 9- Click on the navigator and right-click on the project name(you should see .cdtproject and .project underneath) 10- Select new file if you want to create new c files, or import and then filesystem if you want to copy c source code from an another location, then choose directory where the files are located, select the files and then finish. If the files are spread into different folders, create folders in the project and then import the files in each folders. 11- If the makefile is made correctly with the right compiler after CC you should be able to build the executable. Click on project and unclick build automatically (It's personal. I prefer that). Then click on Ctrl-B to build it. Ifyou did the aforementioned steps, it should work fine. Verify that the executable (.elf file) is present in the folder. Test it on the command line. 12- Now click on Window, open perspective, debug 13- Click Run, Debug... 14- In main, give a new name(it must be the same name as the .elf file) to the configuration, select the right project and select the right .elf file in C/C++ Application 15- In Debugger, browse into your filesystem and find the debugger executable. Select it in GDB debugger. Then, select the .ini file in GDB command file (in our case gdb_load.ini). it should be C:\mspgcc\bin\msp430-gdb.exe if you installed mspgcc in C:\. Select the TCP Connection, choose localhost for the Host name and type for the port number. If the steps 3, 4 5 and 6 above worked, you should see %CygwinGDBDebugger.name or mspgcc GDB debugger in the form Debugger. If not, redo these steps. 16- In source, select the right project name 17- Run the msp430-gdbproxy program to open the connection and leave the window open 18- Click Apply and Debug. 19- You should see a breakpoint at the beginning of the program click resume. You should see the program running! for more details on how to debug please read the documentation but it's not harder than visual studio.

has anyone implemented bit-banging i2c code for both the master and slave for the msp430s? i am working with the olimex kit which has the msp430f449, but any input in this direction will be helpful. thank you, karan CM II Resolution Systems Inc.

G'day, How do I find the top most address of flash used by applications at runtime? I want to load and execute applications under the control of a monitor program. Is there a symbol that can be queried for this purpose? At this point of time, I only managed to do this by creating a section that is placed at the top flash memory address that can be queried by the application, see below: Assembler Code: .section Boundary .global HiFlash HiFlash:; .end section information found in monitor.lst [...] CONTENTS, READONLY, DEBUGGING 16 Boundary 2320 2320 cf8c 2**0 [...] Test output from monitor program info Highest flash address used by monitor = 0x2320 Which indeed is, with the exception of the interrupt vector table, the highest address used by the monitor program. Is this the way to do it or is there an easier way? Sysinfo: NetBSD-i386-2.0G, mspgcc/gcc-3.4.0, msp430x149 cheerio Berndt

c302 PLANT_TickHandler:
/*/
/** \brief Tick processing.
* \par Functional Description:
* This is the low level driver for the relays for the RWG outputs.
* It checks the state of the power supply and if shit is about to happen,
it will
* shut off all the relays. If the power is OK it checks for discrepancies
between
* the desired and required output states. If there is and it is not
protecting
* the plant against rapid mode changes, it will instigate a change. Any
change will
* result in all the relays being refreshed. If the relays have not been
checked for
* a while, it will refresh their state.
*
* Not all the possible output functions can be mapped to the relays at any
one
* time. The plant info arrays define which virtual outputs are mapped to
physical
* outputs as well as the ports to which they are mapped.
* \par Usage:
* This function MUST be added to EXEC_InitSW() in exec.c if you want your
software
* packages configured properly!
