Error when usiing TFTP SCript in Uboot to flash images to QSPI

I have a cyclone V enclustra SA2 module that I am trying to Flash through QSPI using ethernet. While I am able to individually flash each file to QSPI using TFTP, I am unable to flash when using the script provided on the enclustra github page ( . I have created the cmd.txt file and converted to the cmd.img file as specified in the website and establish TFTP connection but see the below messages when executing the script. I am not sure I understand what might be going wrong here. The TFTP folder exists and there is no permission issue since I am able to transfer the cmd.img file through TFTP. I would greatly appreciate it if I could get some pointers on what might be going wrong.
