The issue you are facing usually arises when the Linux file system on the board is mounted as read-only and thereby preventing you from creating directories or modifying files.
You can follow the below steps to rectify the issue:
- Verify the current mount status of the file system. Connect to the Zed Board using a terminal (e.g., via SSH) and run the following command:
mount | grep /mnt
- If the file system is mounted as read-only, you may need to remount it as read-write using the following command:
sudo mount -o remount,rw /mnt
- Replace “/mnt” with the specific mount point if it's different.
- If the issue persists, consider re-flashing the SD card with a fresh Linux image provided by Xilinx. Ensure that you have the correct image for your ZedBoard and that it supports the SoC Blockset functionalities you need.
- Ensure you have the right permissions and ownership for the directories you are trying to modify. You can change ownership with:
sudo chown -R user:group /mnt/directory
- Replace “user” and “group” with the appropriate user and group names.
