L1981 "no copydown created" - what am I missing?

Question asked by Tom Collins on Jun 16, 2010

HC08, CodeWarrior for Microcontrollers v6.3, IDE version 5.9.0 build 5292.

 

Using Start08.c, .prm file for project includes a "COPY" (segment? org?) in the placement section.

 

What do I need to change in order to allow static variables in my functions to be initialized.  I'm trying to get a cross-platform library working on this target, and really need to make use of static variables if at all possible.

 

I'm an experienced C and embedded programmer, but very green with CodeWarrior and Freescale.  Explicit instructions without too many abbreviations (WTF does feeding the COP mean in Start08.c?) appreciated.

 

I was given a skeleton project file as a starting point, since it's sharing the flash with a bootloader and some shared data, so using the Project Wizard is likely out of the question.

 

Here are the SEGMENTS and PLACEMENT sections of my .prm file:

 

 

SEGMENTS /* Here all RAM/ROM areas of the device are listed. Used in PLACEMENT below. */    Z_RAM                    =  READ_WRITE   0x0080 TO 0x00FF;    FLASH_RAM                =  READ_WRITE   0x0100 TO 0x01FF;        /* Reserved for flash code that executes in RAM */    SHARED_RAM               =  NO_INIT      0x0200 TO 0x0215;        /* Used to send data between bootloader and application */    RAM                      =  READ_WRITE   0x0216 TO 0x087F;        /* The rest of RAM */    /* Application areas */    APP_RESERVED             =  READ_ONLY    0x8000 TO 0x83FF;        /* 1KB storage for app - never touched by BL */    APP_VER_DATA             =  READ_ONLY    0x8400 TO 0x841F;    APP_FLASH_ROM            =  READ_ONLY    0x8420 TO 0x850F RELOCATE_TO 0x100;    APP_ROM                  =  READ_ONLY    0x8510 TO 0xF1BB;    APP_VERSION              =  READ_ONLY    0xF1BC TO 0xF1BF;        /* 4 byte pointer to app version string */    APP_IVT                  =  READ_ONLY    0xF1C0 TO 0xF1FD;        /* Application Interrupt Vector Table */    APP_START                =  READ_ONLY    0xF1FE TO 0xF1FF;        /* Application start address */    /* Bootloader (BL) areas */    FLASH_ROM                =  READ_ONLY    0xF200 TO 0xF2EF RELOCATE_TO 0x100;  /* Flash routines that get copied to RAM */    BOOTLOADER               =  READ_ONLY    0xF2F0 TO 0xFFA9;                    /* Bootloader ROM area */    BL_VERSION               =  READ_ONLY    0xFFAA TO 0xFFAD;                    /* 4 byte pointer to BL version number */ENDPLACEMENT     SHARED_DATA            INTO SHARED_RAM;    _DATA_ZEROPAGE,                                 /* zero page variables */    MY_ZEROPAGE            INTO Z_RAM;    FAR_RAM,                                        /* non-zero page variables */                           DEFAULT_RAM            INTO RAM;    APPLICATION_VERSION    INTO APP_VER_DATA;    FLASH_ROUTINES         INTO APP_FLASH_ROM;        _PRESTART,                                    STARTUP,                   /* startup data structures */        ROM_VAR,                   /* constant variables */    STRINGS,                   /* string literals */          VIRTUAL_TABLE_SEGMENT,     /* C++ virtual table segment */    DEFAULT_ROM,    COPY                   INTO APP_ROM;            /* copy down information: how to initialize variables */  END

 

 

Thanks in advance for any guidance.
