It seems that your eMMC is full. Try to free space (for example with apt-get clean)

df -h shows you the usage.

Hi all,
thanks Nicolai. I tried this and after executing "apt-get clean" the black screen is gone and I get a login dialog on the desktop but it reappears all the time without continuing.
My application is very small (around 400KB src + 600 KB exe). How is it possible to get into a memory leak?

Hi Harry,

try to login on the tty console (CTRL + ALT + F1-3) and try again. As the system hasn't any disk space left the graphical environment can fail (cannot write temp data). I would also uninstall unused software packages and clean up the home dir.

The following command lists all files with their size in the current directory and sorts them by size:

Hi Dirk, Nicolai,

the issue could be resolved with writing the default stretch image. Then I updated the system and installed some packages. My application is running fine now.
I cant explain what went wrong with the first installation procedure.

There should be enough available memory, this is the overview in the end:

Thank you very much for your help!

@JEPOYTEK how is it going? Do you still have the error?
