我尝试按照用法部分的说明进行操作：

  • 获取gdbstub项目并将文件放在项目中名为“ gdbstub”的目录中。您可以通过签出Git仓库，或者将Git仓库作为子模块添加到项目中（如果它已经在Git中）来实现。 （完成）
  • 修改Makefile。您需要包括gdbstub源：如果您的Makefile的结构类似于Espressif示例中的结构，则可以将gdbstub添加到SUBDIRS定义中，并将gdbstub/libgdbstub.a添加到{{1 }}定义。另外，您可能希望将COMPONENTS_eagle.app.v6添加到编译器标志（-ggdb）中，如果要调试，请将所有优化标志（-O，-O2等）更改为TARGET_LDFLAGS。最后，确保您的Makefile也可以编译.S文件。

问题来了。我没有SUBDIRS定义，但是我发现

行 
-Og

所以也许最后我应该像这样添加gdbstub？

MODULES     = mdns driver user

我没有找到类似MODULES = mdns driver user gdbstub 的东西，所以我不知道将COMPONENTS_eagle.app.v6放在哪里。 gdbstub/libgdbstub.a我曾经在-ggdb中受过教育（不是CFLAGS），在TARGET_LDFLAGS中也受过-Os，因此将其更改为CFLAGS。

  • 通过编辑gdbstub-cfg.h来配置gdbstub。您可以调整很多选项：FreeRTOS或裸SDK，私有异常/断点堆栈，控制台重定向到GDB，等到调试器附件等。您还可以通过在Makefile文件中包含适当的-Dwhatever gcc标志来配置这些选项。 （此文件未更改任何内容）

gdbstub-cfg.h：

-Og
  • 在user_main.c中，添加一个#ifndef GDBSTUB_CFG_H #define GDBSTUB_CFG_H /* Enable this define if you're using the RTOS SDK. It will use a custom exception handler instead of the HAL and do some other magic to make everything work and compile under FreeRTOS. */ #ifndef GDBSTUB_FREERTOS #define GDBSTUB_FREERTOS 1 #endif /* Enable this to make the exception and debugging handlers switch to a private stack. This will use up 1K of RAM, but may be useful if you're debugging stack or stack pointer corruption problems. It's normally disabled because not many situations need it. If for some reason the GDB communication stops when you run into an error in your code, try enabling this. */ #ifndef GDBSTUB_USE_OWN_STACK #define GDBSTUB_USE_OWN_STACK 0 #endif /* If this is defined, gdbstub will break the program when you press Ctrl-C in gdb. it does this by hooking the UART interrupt. Unfortunately, this means receiving stuff over the serial port won't work for your program anymore. This will fail if your program sets an UART interrupt handler after the gdbstub_init call. */ #ifndef GDBSTUB_CTRLC_BREAK #define GDBSTUB_CTRLC_BREAK 1 #endif /* Enabling this will redirect console output to GDB. This basically means that printf/os_printf output will show up in your gdb session, which is useful if you use gdb to do stuff. It also means that if you use a normal terminal, you can't read the printfs anymore. */ #ifndef GDBSTUB_REDIRECT_CONSOLE_OUTPUT #define GDBSTUB_REDIRECT_CONSOLE_OUTPUT 1 #endif /* Enable this if you want the GDB stub to wait for you to attach GDB before running. It does this by breaking in the init routine; use the gdb 'c' command (continue) to start the program. */ #ifndef GDBSTUB_BREAK_ON_INIT #define GDBSTUB_BREAK_ON_INIT 1 #endif /* Function attributes for function types. Gdbstub functions are placed in flash or IRAM using attributes, as defined here. The gdbinit function (and related) can always be in flash, because it's called in the normal code flow. The rest of the gdbstub functions can be in flash too, but only if there's no chance of them being called when the flash somehow is disabled (eg during SPI operations or flash write/erase operations). If the routines are called when the flash is disabled (eg due to a Ctrl-C at the wrong time), the ESP8266 will most likely crash. */ #define ATTR_GDBINIT ICACHE_FLASH_ATTR #ifndef ATTR_GDBFN #define ATTR_GDBFN #endif #endif 并在user_main中的某个位置调用#include <../gdbstub/gdbstub.h>。 （完成）
  • 编译并刷新您的电路板。 （存在编译问题）

在编译程序时，它显示了很多错误：

gdbstub_init();

能帮我吗？预先感谢。

答案 0 :(得分：0)

您可以在您的Makefile中如下定义SUBDIR和COMPONENTS_eagle.app.v6。

COMPONENTS_eagle.app.v6

SUBDIRS = \     gdbstub

COMPONENTS_eagle.app.v6 = \         gdbstub / libgdbstub.a
