Then the download link for OS 4.0 in https://github.com/nspire-emus/firebird/wiki/First-Time-Setup is misleading, you should fix it.

I have tried with OS 4.0.3 downloaded from ti planet link. ndless installs but then I can not run giac.tns nor khicas.tns, it just reboots
Warning (1219d8d0): Resetting due to watchdog timeout
This happens for both alpha and released firebird.
In other words, it took me 2 hours to try to upgrade to a better configuration, and in the end it's unusable :-(
I think that unless somebody sends me the required files (flash and snapshot) I abandon.

Let me guess, no tns works at all? That means a key is stuck. (Ctrl or Shift, most likely).
Restart firebird and the emulation.

If it still doesn't work, I'll send you both files.

I'll just say that for real-time help instead of waiting for forum replies, IRC is a much better medium - things would have been solved in a matter of minutes :P
(there is a dedicated Firebird channel: #firebird-emu on EFNet)

And yes, [Ctrl] is bound to [Cmd] on Mac. Generally the keymap is trying to be as easy as possible.

Indeed restarting firebird and resetting worked.
It seems I can now debug!! these 2 days were not lost after all :-) thanks for the help (I think this should be copied somewhere in a troubleshoot documentation page).

I got a backtrace of the "1°" crash: It's a stack overflow.
giac::chartab2gen("1°") calls gen("1°"), which calls giac::chartab2gen("1°") and so on:

Mise a jour de khicas http://www-fourier.ujf-grenoble.fr/~parisse/calc/khicas.zip (note aux admins: ca meriterait sans doute une mise a jour dans la section des Archives).
Nouvelle commande en beta-test tabvar qui affiche un tableau de variations, par ex.
tabvar(sin(x))
Fonctionne aussi pour des courbes parametriques, par ex. tabvar([cos(2t),sin(3t)])
Je ne sais pas dans quelle mesure il est possible de faire afficher les etapes intermediaires (recherche du domaine, de certaines symetries et des asymptotes) comme dans la derniere version de Xcas.

Le téléchargement de la page d'archive est en fait externe vers cette adresse-là, donc ça devrait être tout bon :)
