Make cload Error

[kul46]

Hello, I am using Ubuntu 24.04.01 LTS and installed the cfclient and firmware. However, on following the "Getting started with development" doc I am getting this error when I use the last "make cload" command. Would really appreciate any help to flash the firmware successfully.

$ make cload
