Marcin,
I had a similar issue that I think I solved by checking on
CYGHWR_HAL_I386_PC_LOAD_HIGH (This option enables building RAM
applications which have a start address outside of the area used by
redboot_GRUB.) The other description says 'Load into higher memory
(2MB)'.

Have you tried that?

I really stuck on this problem for i386 target. I've searched maillist
several times and found only this thread:

http://sourceware.org/ml/ecos-discuss/2006-04/msg00184.html

Which is about exactly the same problem as I have.

I tried also both types of discovering available RAM - bios and
hardcoding. No results. All I need is about 1MB for application...

Thanks in advance for any help

Marcin

FLOPPY startup will only load into the bottom 640K and will only use
memory in that area. It is really only intended for use with RedBoot,
although applications that can live in 640K will work too.

To run applications above 1M either load RAM startup applications with
a FLOPPY RedBoot, use a GRUB-loaded RedBoot to load them, or load the
application directly using a GRUB startup type.

Laurie,

Yesterday I tried your tip, but it didn't help in my case. I will
explain how I do it:

I take i386 Realtek template, choose redboot in packages, then I go to
eCos HAL -> i386 architecture -> I check Load into higher memory (I
accept solutions for conflicts) and then I go for Startup type - I
change it for floppy and I get a conflict that I should use GRUB, but I
discard a solution so it stays Floppy. It builds fine and image starts
properly but still the same amount of available RAM appears (about 64k) 

Any ideas??? Thanx;)

Marcin

I boot from floppy and it still works.
You can search for the macro name in configtool using 'Edit/Find'.

OK, now I understand, I had to select for GRUB startup... But what if I
want to boot form floppy????
