求助！MC68HC908JL8芯片的编译问题

只看该作者 · 2010-8-22 14:27

小弟是新手。最近在用MC68HC908JL8做实验。这款芯片和匠人的那本书里是一个型号。我使用从网上下载的codewarrior 6.2（不知如何**）进行编译，被告知out of allocation space in segment RAM at address 0X14A.
segments定义如下：
SEGMENTS /* Here all RAM/ROM areas of the device are listed. Used in PLACEMENT below. */
Z_RAM                   =  READ_WRITE 0x0060 TO 0x00FF;
RAM                   =  READ_WRITE 0x0100 TO 0x015F;
ROM                   =  READ_ONLY 0xDC00 TO 0xFBFF;
/* INTVECTS                =  READ_ONLY 0xFFDE TO 0xFFFF; Reserved for Interrupt Vectors */
END
敢问大侠，是不是我用的codewarrior受限，只能编译这么多代码？有什么方法能找到没限制的codewarrior？如果找不到，有没有其他的什么开发环境能够支持MC68HC908JL8芯片？
期盼高手能帮小弟解答。拜谢！

不会的,没有**也是32K限制的
你是否重新建立的项目呢?

要么用的内存过多，减少一下全局变量试一下

是的。是在原有代码基础上建立的新项目。
Project.prm内容如下：
SEGMENTS /* Here all RAM/ROM areas of the device are listed. Used in PLACEMENT below. */
Z_RAM                   =  READ_WRITE 0x0060 TO 0x00FF;
RAM                   =  READ_WRITE 0x0100 TO 0x015F;
ROM                   =  READ_ONLY 0xDC00 TO 0xFBFF;
/* INTVECTS                =  READ_ONLY 0xFFDE TO 0xFFFF; Reserved for Interrupt Vectors */
END
PLACEMENT /* Here all predefined and user segments are placed into the SEGMENTS defined above. */
DEFAULT_RAM                      /* non-zero page variables */
                                    INTO  RAM;
_PRESTART,                         /* startup code */
STARTUP,                         /* startup data structures */
ROM_VAR,                         /* constant variables */
STRINGS,                         /* string literals */
VIRTUAL_TABLE_SEGMENT,             /* C++ virtual table segment */
DEFAULT_ROM,
COPY                               /* copy down information: how to initialize variables */
                                    INTO  ROM;
_DATA_ZEROPAGE,                   /* zero page variables */
MY_ZEROPAGE                      INTO  Z_RAM;
STACKSIZE 0x30
VECTOR 0 _Startup
