无编号警告类型：1、Sat Jun 23, 2012 17:41:05: The stack pointer for stack Stack (currently Memory:0xF5336) is原因：/s/blog_4c0cb1c0010153l9.html????IAR相关设置：Tools-Option-Stack-Warn when stack pointer is out of bounds.?2、无法查看结构体/共同体/联合体变量[Syntax error, unexpected $end, expecting COLON2] column 1? struct? drpoint? {???? uint16 x;???? uint16 y;?? }drpoint[10];?改成：? struct??? {???? uint16 x;???? uint16 y;?? }drpoint[10];?参考：/group/lpc2000/messages/34213?threaded=1m=evar=1tidx=1?UESTC 2012.12?IAR 各版本BUG错误修正历史：/pub/efo-ftp/TMP/pub/atmel/_AVR32_MCUs_32bit/Compilers/IAR/IAR_2.20/Install software/EWAVR32-KS-CD-220A/doc/common/doc/CorrectedProblems.pdf有编号警告类型：?Error[e16]: Segment XDATA_Z (size: 0x19a1 align: 0) is too long for segment definition. At least 0xe4c more bytes needed. The problem occurred while processing the segment placement command-Z(XDATA)XDATA_N,XDATA_Z,XDATA_I=_XDATA_START-_XDATA_END, where at the moment of placement the available memory ranges were XDATA:f1ff-fd53Reserved ranges relevant to this placement:XDATA:f000-f1fe XSTACKXDATA:f1ff-fd53 XDATA_NBIT:0-7 BREGBIT:80-97 SFR_ANBIT:a8-af SFR_ANBIT:b8-c7 SFR_ANBIT:d8-df SFR_ANBIT:e8-ef SFR_ANA：其实这个问题并不是你的程序本身有问题，主要是因为你编写的程序太大了，超出了芯片本身的定义。今天在群里学习了一招，就是将数组定义到code里，我们看一下例子。我们定义一个5100个元素的数组，有以下两种方法：mermaid提出的方法是：typedef unsigned char const __code INT8U;extern INT8U shuzi[5100];文晶提出的方法是INT8U code shuzi[5100];这两种方法其实效果是一致的，定义完数组之后，调用的部分就是需要用指针来调用数组里面的数值了。Error[e16]: Segment DATA16_I (size: 0xa80 align: 0x1) is too long for segment definition. At least 0x27f more bytes needed. Thepro××em occurred while processing the segment placement command-Z(DATA)DATA16_I,DATA16_Z,DATA16_N,HEAP+_HEAP_SIZE=0200-0A00, where at the moment of placement the ××aila××ememory ranges were CODE:200-A00经过验证是由于RAM耗尽，程序里估计有很大的数据量，最好使用const定义到FLASH里面，问题基本可以解决。Error[e16]: Segment DATA16_Z (size: 0x6b9 align: 0x1) is too long for segment definition. At least 0x317 more bytes needed. The problem occurred?while processing the segment placement command?-Z(DATA)
