There are no problems for using most CAMs on TGS100. I have successfully tested the following :
=> evocamd 2.11 + newcs
=> mgcamd + newcs
=> xcamd
=> gbox
Newcamd can not be used because of some devices it try to access that do not exists on tgs100.
Most images, like Juliet or DSTeam, propose download centers that provide fully functionnal CAMs packages with auto installation process. You can also find "install.tar" files that you only have to upload to /var/etc and reboot the demo to get them automatically installed. A lot are available around different boards / sites, for instance with evocamd or gbox.
For my tests, I directly used softcams downloaded from
www.dreamboxworld.com without any problem (excluding newcamd, that start but can not work, as explained before).
