This tutorial shows how to use VisualGDB to build and debug embedded firmware for ARM devices using the GCC ARM toolchain <\/a>maintained by ARM.<\/p>\n

Before you begin, install VisualGDB 5.0+ and download the ARM toolchain from https:\/\/launchpad.net\/gcc-arm-embedded<\/a><\/p>\n

    \n
  1. Install the GNU ARM toolchain to a directory that does not contain spaces:
    \n    \"gnuarmdir\"<\/a><\/li>\n
  2. Enable the “Add Registry Information” checkbox on the last page of the toolchain installer:
    \n    \"gnuarm\"<\/a><\/li>\n
  3. Launch Visual Studio and start creating a new project via File->New Project->VisualGDB->Embedded Project Wizard:\"prj\"<\/a><\/li>\n
  4. Proceed with the default settings on the first page of the wizard:
    \n    \"def\"<\/a><\/li>\n
  5. VisualGDB should automatically detect the toolchain location and show it in the toolchain list as “GNUARM”. Select it and then choose your device:\"device\"<\/a>If the toolchain location is not detected, check the HKLM\\SOFTWARE\\Wow6432Node\\ARM\\GNU Tools for ARM Embedded Processors\\InstallFolder<\/strong> value in the registry. The GNU ARM toolchain installer should set it to the toolchain location.<\/li>\n
  6. Select the sample you want to use for your project. The simplest one is LEDBlink:\"sample\"<\/a><\/li>\n
  7. Select the debug method you want to use. You can read here <\/a>about various debug methods supported by VisualGDB.\"debug\"<\/a><\/li>\n
  8. Press “Finish” to create the project. Build it by pressing Ctrl-Shift-B:\"build\"<\/a><\/li>\n
  9. You can start debugging the project like any other Visual Studio project by pressing F5:\"debug\"<\/a><\/li>\n
  10. You can change various toolchain settings by right-clicking on the project in Solution Explorer, selecting “VisualGDB Project Properties” and changing the settings on the first page. E.g. you can switch the C library from newlib to newlib-nano and disable syscall support to reduce the size of your image:\"settings\"<\/a><\/li>\n
  11. If you build your project now, you will see that its size has decreased substantially after we switched to the lightweight newlib-nano library:\"smaller\"<\/a><\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
