Keil 调试ARM时出现的 *** error 65: access violation at xxxx
实验用soc:s3c2440 分析原因:内存访问权限错误 解决办法: 1. 调试 开始后使用map命令进行分段更改内存访问权限 例如 调试 小程序时,仅在0~4kB范围内寻址时, 出现 : *** error 65: access violation at 0x00000FFC : no 'write' permission *** error 6
实验用soc:s3c2440
分析原因:内存访问权限错误
解决办法:
1.调试开始后使用map命令进行分段更改内存访问权限
例如调试小程序时,仅在0~4kB范围内寻址时,出现:
*** error 65: access violation at 0x00000FFC : no 'write' permission
*** error 65: access violation at 0x000000B4 : no 'write' permission
...
等错误
在command窗口输入
map 0,4095 read write exec
回车,PC复位,Go,即可解决问题。
更多解释:
map命令更改内存访问权限只能对16MB以内的区域进行设定
使用规则如下:如需更详细,请参见Keil的Help文档
Syntax | Description |
---|---|
MAP | Displays the current memory map. |
MAP start, end READ WRITE EXEC VNM | Maps the specified memory range (start-end) accesses as specified. |
MAP start, end CLEAR | Clears a mapped memory range. |

It allows Windows to manage how applications work in the background. For example, once you enable battery saver mode to preserve battery, the system will automatically close all apps. 5. Select [Never] to prevent the application from running in the background. Please note that if you notice that the program is not sending you notifications, failing to update data, etc., you can

DeepSeek cannot convert files directly to PDF. Depending on the file type, you can use different methods: Common documents (Word, Excel, PowerPoint): Use Microsoft Office, LibreOffice and other software to export as PDF. Image: Save as PDF using image viewer or image processing software. Web pages: Use the browser's "Print into PDF" function or the dedicated web page to PDF tool. Uncommon formats: Find the right converter and convert it to PDF. It is crucial to choose the right tools and develop a plan based on the actual situation.

How to use LeakSanitizer to debug C++ memory leaks? Install LeakSanitizer. Enable LeakSanitizer via compile flag. Run the application and analyze the LeakSanitizer report. Identify memory allocation types and allocation locations. Fix memory leaks and ensure all dynamically allocated memory is released.

This article introduces shortcuts for Go function debugging and analysis, including: built-in debugger dlv, which is used to pause execution, check variables, and set breakpoints. Logging, use the log package to record messages and view them during debugging. The performance analysis tool pprof generates call graphs and analyzes performance, and uses gotoolpprof to analyze data. Practical case: Analyze memory leaks through pprof and generate a call graph to display the functions that cause leaks.
