[ECOS] Redboot available RAM

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????

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
