Are you happy with how the project is going?

Hello all,

I was able to proceed further via setting rtems_minimum_stack_size manually
to 0x200.
Now I have another error, my backtrace:

Is RTEMS trying to allocate 2976696 bytes?
It seems to me, that .data region is not properly initialized. What do you
think about this?
