Hi Enrico,
I'm not sure what are you reffering to when you say bootloader env, but 
here's what I get on my console:

All I did to build it, was to add meta-ti to my bblayers.conf and try 
bitbake with MACHINE=pandaboard. The build was screaming about some QA 
errors, which I had to disable to get the build finish. I'm assuming 
those are the reason for my failure. However, I did not investigate 
further into these.

Thanks,
Radu
