【求助】ADS调试ARM板出现Data Abort 错误（系统是uCOS）

要善于利用百度google啊。。。 if you look at the ARM ARM (ARM Architecture Reference Manual, just google "arm arm"), Programmers Model -> Processor modes and Registers sections. When in abort mode you are priveledged so you can switch from abort to say supervisor and then make a copy of r13, then switch back to abort mode and dump the stack from the copy of r13. Your r14 also tells you where the abort occurred. I wouldnt be surprised if this abort was from an alignment. Trying to read/write a word with an address with something other than zeros in the lower two bits or a halfword with the lsbit of the address set. Actually if you take the link register and a dump of the registers (r0-r12) since abort and user/supervisor use the same register space, you can look at the instruction that caused the abort and the address to see if it was indeed an alignment problem or something else. Note that the pc is one, two or three instructions ahead depending on the mode thumb or arm that had the abort, if you are not using thumb at all then this nothing to worry about. 【 在 ChandlerWang (Chandler) 的大作中提到: 】 : 小弟刚上手arm+uC/OS-ii，现在有个2410的开发板，上面有个wince的系统。 : 目前还没有移植其他系统，是直接在SDRAM上跑uc和一些简单的任务。 : 但是ADS在编译和make之后，debug后，打开了AXD和JTAG，向板中下载程序 : ...................

关键是不懂。。。好好研究研究。。。谢谢~~~ 【 在 ArmStrong 的大作中提到: 】 : 要善于利用百度google啊。。。 : if you look at the ARM ARM (ARM Architecture Reference Manual, just google "arm arm"), Programmers Model -> Processor modes and Registers sections.

楼主的问题解决了么？我也遇到了同样的问题。。。
