libnjb-tools binary package in Ubuntu Focal riscv64

 libnjb is a C library and API for communicating with the Creative
 NOMAD JukeBox and Dell DJ digital audio. The protocol these devices
 use is presumably called PDE (Portable Digital Entertainment protocol)
 at Creative. Newer devices using the Microsoft MTP (Media Transfer
 Protocol) are not supported.
 .
 This package contains the library tools each performing a simple
 function, such as transferring a track to the jukebox. The source
 code for these tools is in the package libnjb-doc.
