I can't exit on rotating arrow app. I want to open terminal. #20

I'm running ubuntu on a MAC, usign VMware Fusion, so it's a virtual ubuntu machine, also I've a SDcard USB adapter to get mount the cards. Every time I want to access the SD files in the ROOT partition it's Read Only Filesystem. I can' do nothing to modify a file there. So, I can't apply your suggest in another issue: Change the line console::respawn:/sbin/getty -L console 0 vt100 # GENERIC_SERIAL to ttyAMA0::respawn:/sbin/getty -L ttyAMA0 0 vt100 # GENERIC_SERIAL

Neither as superuser, or root user. Maybe it is because I use a sd adapter ? Or blame the virtual machine ... I don't know.

To check a fast boot and run my own code, first, i will try as you suggested other guys, the simple HelloWorld app. That's a very good idea. !!

Thank you & Cheers ! Rick.

Finally I was able to modify the inittab file in the card ! (I should use another PC with ubuntu). Now when I boot the pi with your example, it only shows arrows images rotating on the screen, and by serial I get this messages below.... Why I can't see another image on my monitor ? Is is normal ?

Thank you Furkan !! Now I'll about the terminal problem, and then, realize a simple "HelloWorld" program to let it work instead your app.

Ok, at this point I've the terminal working fine, and in it, I can see the board booting AND the HelloWorld text also! So it's a success! Now is coming the "hard" part to get my real app working after a short time boot.... Maybe it takes me a lot of time, since statically compile it, seems to be a nightmare with my poor knowledge.

Anyway, again thank you so much for your support Furkan. Cheers. Rick.

Nice!

https://github.com/furkantokac/buildroot/blob/ftdev/build-rpi3-qt.sh This script statically compiles the Qt. You can use this as a reference. FT_CROSS_COMPILE and FT_SYSROOT what you'll need to. As I said before, if your app is not rely on some kernel features or graphical interface, it should not be that hard.

You'll do it. Keep going!

Dear Furkan. Magically I've got compile my app statically much faster as I hope. That's great for me. I've tested the app with another raspian PI card, and works fine in static way, but. When I try to get it work with the card generated by the "fastboot", I get the following error in the serial, and also can't see any graphics on screen, only the four raspberry images:

Starting syslogd: OK Starting klogd: OK Initializing random number generator... done. /root/a.out: error while loading shared libraries: libasound.so.2: cannot open shared object file : No such file or directory

Obviously the name of the app is a.out, and I never use that 'libasound' lib in the code ??? Is is a dependency of the main library ? Now, how to solve this so ?

Cheers! Rick.
