Re: i386 problem


Thank you, Mr. Nick Garnett.
I will try to do what you said.
I will now try to start using Redboot during the development.

Thank you again.

GonÃalo Antunes.

Hello again!

I tried to start with a plain net template, changed the HAL_STARTUP to
FLOPPY and the error on the "make tests" is the same:

>> /home/gmma/config_install/lib/vectors.o:/tmp/ccfRQjJM.s: undefined
>> reference
>> to 'hal_saved_interrupt_state'
>> make: leaving directory '/home/gmma/config_build'
>> collect2: ld returned 1 exit status


If I put it to RAM, it works fine...


When I first installed ecos (without any CVS update), the FLOPPY
startup worked fine...

What can I do?

The main problem seems to be with the profiling support that Bart added in March. I'll leave him to decide what to do about it in the repository, but in the interim you could try moving the

#endif // CYGPKG_PROFILE_GPROF

in hal_misc.c to just after the

#endif // SMP

I've not tried this, so I have no idea whether it will work.


However, FLOPPY startup only allows for applications that occupy the lower 640k of RAM. Given all the packages you want to load, you may find this a bit of a squeeze. You would be better off using the GRUB startup type for large stand-alone programs, since these get loaded into RAM above the 1Mb boundary.

During development, you should be using RedBoot and load RAM
applications. You should only switch to FLOPPY or GRUB startup when
you are ready to turn in to a product, not before.
