    • J-Link Semihosting: Is There a Limit on Directory Depth for File Open?

      Hi,

      I'm using J-Link semihosting to open files on the host system, and I've noticed an issue with deeply nested directories.
      When opening a file with a path up to five levels deep (e.g., C:/1/2/3/4/5/file.txt), everything works fine. However, if the file is located in a deeper directory (e.g., C:/1/2/3/4/5/6/f.txt), the file open function fails.

      Is there a known limitation in the J-Link semihosting implementation regarding directory depth? Or could this be a bug or an issue with my setup?

      Any insights would be appreciated!

      Thanks in advance.

      Hello,

      Semihosting itself is not limited in path length.

      However, depending on the tool you are using on the PC side, the path length could be limited to 256 characters (the maximum path length in Windows).
      May I ask which tool you are using for semihosting? So i can check if there is a limitation in that specific tool.

      Best regards,
      Simon
