常见问答 / 在 Keil/IAR 开发环境的除错模式(Debug Mode)下,当程序全速执行(Free Run)时,使用者可以立即增加新的断点吗?



Breakpoint 在 Keil/IAR 开发环境的除错模式(Debug Mode)下,当程序全速执行(Free Run)时,使用者可以立即增加新的断点吗? 1426759740000 由于Nu-Link驱动会在程序全速执行前,才将设定的断点信息加入。而在程序全速执行时加入的断点,Nu-Link驱动会先加入缓存中。因此,新加入的断点必须在用户停止程序并且重新执行后,才能正确地执行。


常见问答 / 在keil开发环境中,如何增加一个断点,使得当某个寄存器或RAM的某个地址被改变或读取时,程序会停止执行?



Breakpoint 在keil开发环境中,如何增加一个断点,使得当某个寄存器或RAM的某个地址被改变或读取时,程序会停止执行? 1441789447157 在调试模式(DEBUG Mode)下,请根据以下步骤增加断点: 使用快捷键组合Ctrl + B打开断点对话窗口; 在断点对话窗口的“Expression”一栏内输入要查看的寄存器或RAM的地址; 在右侧“Access”区域内,勾选“Read”或“Write”的条件,更改“Size”为数据长度,如寄存器的话需要更改为4;勾选“Bytes”单位; 点击“Define”增加新的中断点。 以M051系列为例,如果要查看UART0的UA_THR寄存器是否有值写入,请依下图所示设定: 注 1:不能够通过设置Count的值来控制中断点的数量。 注 2:一个寄存器最多只能设置2个中断点。

常见问答 / 用户在使用ICP工具/Keil RVMDK/IAR EWARM时,对Nu-Link/Nu-Link Pro/Nu-Link-Me进行升级时,若操作不当可能会产生什么样的问题?如何解决?



用户在使用ICP工具/Keil RVMDK/IAR EWARM时,对Nu-Link/Nu-Link Pro/Nu-Link-Me进行升级时,若操作不当可能会产生什么样的问题?如何解决? 1450678500000 用户在使用ICP工具/Keil RVMDK/IAR EWARM时,Nu-Link/Nu-Link Pro/Nu-Link-Me固件与ICP驱动版本不匹配时,会提示用户升级。在升级未完成时插拔Nu-Link/Nu-Link Pro/Nu-Link-Me会导致其无法正常使用。 可通过以下两种方法使Nu-Link/Nu-Link Pro/Nu-Link-Me恢复正常: 方法一: 重新打开ICP工具,继续对Nu-Link/Nu-Link Pro/Nu-Link-Me固件升级,升级完成后Nu-Link/Nu-Link Pro/Nu-Link-Me所有功能皆可恢复正常。 方法二: 使用另一个Nu-Link/Nu-Link Pro或Nu-Link-Me与无法正常使用的Nu-Link/Nu-Link Pro或Nu-Link-Me连接,如下图所示: 将配置文件“NUC1xx_ICE_M0.bin”载入到ICP工具的APROM中。该文件可在ICP工具的安装目录下找到。设置启动选项为APROM启动,选用外部晶振时钟。下载完成后,除了ID号显示为ffffffff之外,如下图所示,Nu-Link的所有功能均可正常使用,可通过下一步恢复其ID号。 选择不同版本的ICP工具,连接时工具会提示是否对Nu-Link/Nu-Link Pro/Nu-Link-Me进行升级,选择“是”,软件会自动设置好设备的ID号。

常见问答 / 如何解决在新唐开发板使用 Arm library 并以 C++ 进行机器学习程序开发时,只能运行 Debug mode 而无法正常执行的问题? (disassmebly 内持续看到 BKPT 出现)



Machine learning, ML, Continual breakpoints 如何解决在新唐开发板使用 Arm library 并以 C++ 进行机器学习程序开发时,只能运行 Debug mode 而无法正常执行的问题? (disassmebly 内持续看到 BKPT 出现) 1683014520000 若发生在 debug mode 可运行,但不接 ICE 直接 free run 程序会卡住,且从 debug mode 发现程序持续卡在断点的现象时,可能是 semihosting 错误。 在新唐机器学习范例中使用 Arm library 时,若在出现「stdout/stdin/stderr multiply defined…」等错误警告时,直接将重复定义的项目删除便会导致 semihosting 错误而发生程序不断进 breakpoint 的现象。 NOTE: 为避免 semihosting 错误问题,在删除重复定义的项目后,需在 retarget.c 内新增下列程序代码: extern void $Super$$_sys_open(void); FILEHANDLE $Sub$$_sys_open(const char *name, int openmode) { return 1; /* everything goes to the same output */ } (若编译中有其他 L6200E 函数错误警告 (Symbol _sys_XXX multiply defined),请一并新增 sys_XXXX() 的 FILEHANDLE 定义)
