Works for me. I suggest you talk to your network administrator and see
if your firewall is causing you a problem.
I tried it again a little later without the 2401 and it worked
fine. I'm guessing that the 2401 was causing me some problems.
I'm the admin and I don't think that any ports are blocked
going out. Except for MS stuff (Netbios et al).
Second question. I'm working with the AT91EB40A board.
I have external RAM (@0x2000000). When I attempt to
d/l an srec (compiled by gcc, no libraries) It complains
that I doesn't have any RAM there. How do I tell the
compile that I have RAM at 0 (256K internal after remap)
and RAM at 0x2000000 (External, 1Mx16)?
Are you getting a linker error, or is redboot telling you you have not
RAM there?
No linker error, arm-elf-gcc worked fine.
If redboot is the problem you have two options:
1) Disable the checking so that it will allow you to load to any
address. You need to disable CYGSEM_REDBOOT_VALIDATE_USER_RAM_LOADS.
2) Let Redboot know about your extra memory. You need to set
CYGBLD_REDBOOT_MAX_MEM_SEGMENTS to 2 and implement the function
cyg_plf_memory_segment() which reports the extra memory
locations. Take a look at cyg_start() in redboot/src/main.c and
hal/powerpc/moab/current/src/hal_aux.c:cyg_plf_memory_segment() for an
example.
Thanks, I'll try the second one, that looks like it will
do what I want. :-)
