意外位置的地址错误

这3个参数是如何声明的？



      以下为原文

    How are the 3 parameters declared?

I2CYEEPROMYPAGE和I2CYEEPROMETHT来自MCCit产生的EEPROM LIB V1.00是24FC512 EEPROM，EEADR在CARCURNE2CYEEPROMPEX Page之前被检查为页面的开始。



      以下为原文

    typedef struct
{
  unsigned char busAddress; ///< Slave Address bits A2, A1
  I2C_CHANNEL channel; ///< I2C channel identifier
} I2C_EEPROM_T;

#define PAGESIZE (128)

uint32_t ee_adr;
I2C_EEPROM_T eepromInstance={0x50,I2C_EEPROM_CH1};

uint8_t page[PAGESIZE]
 
I2C_EEPROM_PageWrite and the I2C_EEPROM_T are from the EEPROM lib V1.00 generated by MCC
it is a 24FC512 EEPROM and eeadr is checked to be at start of a page before calling I2C_EEPROM_PageWrite
 
if (ee_adr%PAGESIZE == 0)
    I2C_EEPROM_PageWrite (...);

你还*创建了一个“I2CYEEPROMYTHT”类型的EEPROMASTATION变量？



      以下为原文

    You also *did* create a eepromInstance variable, of type "I2C_EEPROM_T" ?

MCC做到了，我把代码插入了最后一篇文章。



      以下为原文

   
 
MCC did, I have inserted the code in last post.

听起来不错：那时还不确定，我从来没有使用过那些库函数…



      以下为原文

    Sounds good enough: not sure then, and I never used those library functions...

仍然有问题。现在我已经从这个线程中插入了来自GUYMC的代码。不幸的是地址数组[0-2 ]的值是0x000。我必须使用一个调用而不是rCALL。为什么我不能得到导致地址陷阱错误的正确地址？这是内联汇编程序：



      以下为原文

    Still have the problem.
Now I have inserted the code from guymc from this thread.
Unfortunately the address array [0-2] has a value of 0x0000.
I have to use a call instead of rcall. 
 
Any idea why I can not get the proper address that cause the address trap error?
 
 unsigned int AbortAddressContainer[3];

 void __attribute__((interrupt(preprologue("call _where_was_i")),no_auto_psv)) _AddressError(void)
 {
    Nop(); // Set breakpoint here. When hit, variable _RA shows the return address
    Nop();
    Nop();
 }
 
and this as inline assembler:
 

 ;
 ; Storage for the exception return address
 ;
 .section *,bss,near
 .global __AbortAddressContainer
 __AbortAddressContainer: .space 4 ; address where the exception occurred
                          .space 2 ; previous word of stack data
 ;
 ; Function to read exception return address
 ; from the stack, plus the previous word
 ;
 .text
 .global _where_was_i
 
 _where_was_i:
 
         push.d w0
         sub w15,#12,w1 ; twelve bytes pushed since last trap!
         mov [w1], w0
         mov w0, __AbortAddressContainer
         mov [w1+2], w0
         mov.b WREG, __AbortAddressContainer+2
         mov [w1-2], w0
         mov w0, __AbortAddressContainer+4
         pop.d w0
         return
 
 ;
 ; Tabulation of stack usage since the exception
 ; occurred (read from bottom to top).
 ;
 ; current SP +12
 ;
 ; push w1 +10
 ; where_am_i push w0 +8
 ;
 ; rcall in PC 22->16 +6
 ; handler PC 15->0 +4
 ;
 ; PC 22->16 +2
 ; TRAP! PC 15->0 +0
