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

(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:

Khicas update http://www-fourier.ujf-grenoble.fr/~parisse/calc/khicas.zip

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.
