keil5 仿真出现ERROR L121:IMPROPER FIXUP如何解决?,如题，用keil5仿真出现了ERROR L121:IMPROPER FIXUP的问题，第一次遇到，那个code也已经是large了，不知道怎么解决。
,源码呢？,

源码呢？
不好意思，才看到，真的不好意思。我把报错部分发上来。
#include “keyboard.h”

//功能；只扫描一个按键，按键为号小优先
//返回键值：
// 1 2 3 10 //10:清零重量，兼去皮功能
// 4 5 6 11 //11:清除单价
// 7 8 9 12 //12:显示数值偏大调节按键
// 14 0 15 13 //14:无功能（用于扩展）15：小数点 13：显示数值偏小调节按键

,I/O口有问题吧，重新拔插一下,

是在keil里不能编译成功，我同时还试了别的程序，正常的。
,楼主解决了嘛 遇到同样问题,bdata 问题 keil5 不认bdata,我今天也遇到了同样的问题,IMPROPER FIXUP,研究了半天终于解决了,原来这个问题是因为Keil4和Keil5不支持bdata的问题导致的,所以退回Keil2,新建工程,加入文件,重新编译就OK了,你这个上面也有bdata所以也可以用我的办法来成功解决的.
参考资料:
The variables ibase and bary are bit-addressable. Therefore, the individual bits of these variables may be directly accessed and modified. Use the sbit keyword to declare new variables that access the bits of bdata variables. For example:
sbit mybit0 = ibase ^ 0; /* bit 0 of ibase */
sbit mybit15 = ibase ^ 15; /* bit 15 of ibase */
sbit Ary07 = bary[0] ^ 7; /* bit 7 of bary[0] */
sbit Ary37 = bary[3] ^ 7; /* bit 7 of bary[3] */
The above example represents declarations, not assignments to the bits of the ibase and bary bdata variables. The expression following the carat symbol (‘^’) in the example specifies the position of the bit to access with this declaration. This expression must be a constant value.
The range depends on the type of the base variable included in the declaration. The range is:
0-7 for char and unsigned char, 0-15 for int, unsigned int,
short, and unsigned short, and
0-31 for long and unsigned long.
并没有定义bit类型的bdata。因此定义成char。
OFDM_PHY_ext char bdata bLib_RxPlcEnd;
OFDM_PHY_ext char bdata RX_BUSY;
OFDM_PHY_ext char bdata TX_BUSY;
Comm_ext char bdata bCommRxEnd;
Comm_ext char bdata bCommRxstart;
