Updating Sysroot for Raspberry PI Cross-Toolchain

This tutorial shows how to update your sysroot directory for the Raspberry PI cross-toolchain. It is highly recommended to update the sysroot after downloading the toolchain, or after switching to a new SD card image.

The sysroot synchronization ensures that the versions of headers and libraries used by the cross-compiler match the versions of the files located on your Raspberry PI board.

  1. Ensure you have downloaded and installed the cross-compilation toolchain.
  2. Run <toolchain>\tools\UpdateSysroot.bat
  3. Click on the "select" button. In the "New SSH Connection" dialog specify the host name of your Raspberry PI board and the login/password. Note that default login is "pi" and the default password is "raspberry".
  4. If you want to synchronize any additional directories, add them to the list in the bottom of the window. Click "Synchronize" to begin the synchronization process:
  5. The synchronization process will start. Depending on the amount of installed libraries it can take 5-20 minutes:
  6. Once the synchronization is complete, you can start using your cross-toolchain. Remember to re-synchronize sysroot after installing new libraries on your device or after changing the used image.
