[ECOS] Newbie question: eCOS and Redboot for AT91SAM7S-EK

[ECOS] Newbie question: eCOS and Redboot for AT91SAM7S-EK

[Wayne Liu]

I am new to eCos and ran into some problems while trying to get started with
eCos and RedBoot ( I've searched through the mail archive, but wasn't able
to much specific information): 
 
1. I've found the eCos page which says that eCos and RedBoot has been ported
to the AT91SAM7S-EK eval board. But I cannot find any package information
specific to this processor or eval board from that page.

2. The same eCos page also claims "Instructions for installing RedBoot on
the at91sam7sT can be found in the RedBoot User's Guide. But I can't find
any mentioning of AT92SAM7S in the RedBoot user's guide either.

I am really confused how I can download and build eCos and RedBoot for my
board. Can someone point me to the right direction?  Any help would be
greatly appreciated!

You need the latest eCos from anonymous CVS:

http://ecos.sourceware.org/anoncvs.html

Personaly, i don't recommend using Redboot with this system. I do all
my development using eCos ROM applications and JTAG for download and
gdb. This removes the need for RedBoot.

You are correct in that there are no instructions for installing
RedBoot. The webpage is generated automatically using server side
includes and i don't think i can turn that off.

[oliver munz @ s p e a g]

For development, RedBoot is worthless. But if You need firmware-upgrades in
the field, then RedBoot can be usefull.
You need ~0x10000 bytes of flash-space (the hole sam7s64) and a
JTAG-emulator.
So i think RedBoot make sens only for the sam7s128 and 256...

Andrew and Oliver,

Thanks a lot for the information. I agree that RedBoot is not appropriate
for such a platform. I always built my own bootloaders on such smaller
embedded platform in the past. But was wondering if eCos must have RedBoot
installed for its HAL is from Redboot.

I am trying to install the CVS client and download eCos now.

eCos does not require RedBoot. Just build ROM applications.

RE: [ECOS] Newbie question: eCOS and Redboot for AT91SAM7S-EK

[Wayne Liu]

I ran into another strange problem: when I try to invoke the ecosconfig tool
through the desktop icon, the ecosconfig tool window displays a bunch of
messages in its output window and then disappears. I dumped the output to a
text file, and it seems to complain that my installation doesn't contain the
"*.cdl" script (see below). 

---- from configtool output window ----

ecos.db, package CYGPKG_HAL: warning
    Version subdirectory `common' does not have a CDL script `hal.cdl'.
ecos.db, package CYGPKG_HAL: warning
    This package does not have any valid version subdirectories.
....

---- end from configtool output window ----

But I can see that there is an "
C:\cygwin\opt\ecos\ecos-2.0\packages\hal\common\v2_0\cdl" directory with
several .cdl files in it. 

I tried a few things but always got the same result:
a) invoke it directly from the cygwin shell command line (after executing
/opt/ecos/ecosenv.sh)
b) pull out the current version via anonymous CVS and run the configtool
there.

Did I do anything wrong with my installation? Or did I miss some steps?
Thanks in advance!

Wayne
