MSP430 - Silicon Erratasheet - USCI28 - Workaround

Sven Flachm��ller

Other Parts Discussed in Thread: MSP430F2132

Hi together,

My environment

Target:            MSP430F2132
IDE:                Code Composer Studio v5
Compiler:        MSP430 v4.1.1

My problem

I want to implement the workaround for the Bug USCI28 of the Device Erratasheet (see www.ti.com/lit/pdf/slaz163 ). My decision was made to paragraph 3 with modifying the boot.c file. I followed the instruction exactly but now there's to few space:

Error:  program will not fit into available


My question

  • Does the possibility exists to enlarge the memory of the RESET vector?
  • Is there another way to solve the problem?

Thank you guys,

Sven

    It sounds like you've ended up with two interrupt service routines defined for the reset vector. Perhaps the linker is still finding the original version as well as the modified one created by following the workaround instructions.

    I checked it without success, the same error occurs. Here is my modificated boot.c file (the section is commented out):

    Do I have to delete a section from the file?

    I also would be happy with a reply directly from TI. When you assemble errors in your products, you should have workarounds that are easy to implement. Directed at TI not Robert!

    Thanks.

    I think there might be a second copy of boot.c coming from the compiled RTS library. Have you tried a clean rebuild of the project? Also, in the build output folder there should be a .map file. Attaching that might reveal what the problem is.

    You could be right. First I tried to compile the software including the workaround and it failed. After I deleted the content of the file and it worked.

    So can you give an advice to me how to solve the problem? I can't delete the boot.c file out of the rtssrc.zip folder because of other projects.

    Perhaps the .map files helps you:

    Had to change the file endings because of the TI upload rules...

    Ok, those map files are interesting. When the workaround is not present the symbol _reset_vector is given the address 0xFFFE (ie the last word of flash memory). With the workaround it instead ends up at address 0x0. That's not in flash memory, it's in the address range of the special function registers (the SFR "IE1" lives at address zero).

    That explains why the linker is complaining: it can't place _reset_vector at 0x0 because IE1 is already at that address. That's just one symptom of the problem, however, the real issue is that _reset_vector is at address zero.

    Looking at the modified boot.c again I can see what the problem is. The USCI28 workaround instruction says "In the copy insert the [workaround] code prior to stack pointer initialization", which is a bit vague. You've put it before this code:

    /*---------------------------------------------------------------------------*/
/* Macro to initialize stack pointer.  Stack grows towards lower memory.     */
/*---------------------------------------------------------------------------*/
#if defined(__LARGE_DATA_MODEL__)
#define STACK_INIT() __asm("\t   MOVX.A\t   #__STACK_END,SP")
#else
#define STACK_INIT() __asm("\t   MOV.W\t    #__STACK_END,SP")
#endif

    ...but that's not where the writer of the workaround intended. The workaround needs to go at the location marked here:

    /*****************************************************************************/
/* C_INT00() - C ENVIRONMENT ENTRY POINT                                     */
/*****************************************************************************/
#pragma CLINK(_c_int00)
extern void __interrupt _c_int00()
{

   // <-- INSERT USCI28 WORKAROUND HERE

   STACK_INIT();

    Thank you! It seems to be the solution of my problem. I can compile the project now without any error!

    So the next "problem" is: I want to test the workaround. But how can I force the error? My rendition of the USCI28 description is, that the error occurs accidentally.
    My system is configured as:
    CPU clock = 8 MHz
    I2C clock = 66 kHz

    Any further good idea?

    If you have access to a digital pattern generator you can use that to emulate the I2C bus for the problem case. The timing window is quite tight though - in your case just 750ns after the interrupt flag is set.
  • 0 in reply to Robert Cowsill

    That would be a good possibility to test the problem case. But now I punched in another question. You gave me the advice to put the workaround code in here (_c_int00):

    /*****************************************************************************/
/* C_INT00() - C ENVIRONMENT ENTRY POINT                                     */
/*****************************************************************************/
#pragma CLINK(_c_int00)
extern void __interrupt _c_int00()
{
       <--- USCI28 BUG WORKAROUND
   STACK_INIT();

   INIT_EXIT_PTRS();
   INIT_LOCKS();

    But I made out, that my software jumps in the initialization function _c_int00_noexit(). And when I implemented the workaround code in there it seems to work. So does the program always jump in the  _c_int00_noexit() function after a reset or does it depend on what kind of reset occurred? Otherwise where is the definition of which initialization function will be used?

    Hope this will be my last question :) Thanks in advance!

    A given program will always jump to the same function after a reset.

    In order to minimize the code size, the compiler/linker can select a different reset function based upon which C run time library facilities are used by the program.

    e.g. with a simple "blink LED" example for a MSP430F2132, which didn't use any global variables, then TI compiler v4.4.5 selected _c_int00_noinit_noargs_noexit as the reset function. Where "noinit" means no global variable initialization and "noargs" means no arguments passed to main.

    Therefore, if your program is modified need to check that the work-around has been placed in the _c_init00 function which is being used.

    It's probably safest to put the workaround in all versions of _c_init00. That way you won't get caught out if changes to your code make the compiler choose a different reset function.

    Fortunately it's not possible. In this case the Label "Start_Normal" would be placed at several locations. That's the reason of not placing the workaround in the macro STACK_INIT(). A possibility would be to place the workaround in each _c_init00 function with different labels as target address. But I drop further adaptions. Thank you guys ;)

    That's a good point. In case anyone else wants to do this I think it's still possible with local labels, like so:

    __asm("\t.newblock"); // Directive to start a new local label block (ensures $0 not already defined)
__asm("\t BIT.B\t #0x08,&0x0001"); // if TXIE is set, errant call occurred
__asm("\t JZ\t $0"); // if not start main program
__asm("\t RETI"); // else return from interrupt call
__asm("$0");
__asm("\t.newblock"); // Directive to start a new local label block (undefines $0)
