Nios II and eCos - David Brown - 2004-06-18 06:22:00

Does anyone know if there are concrete plans for
a Nios II port of eCos?
There are several other OS'es ported to the Nios II already, such as
uC/OS-II and ucLinux, but I've heard nothing regarding eCos other than
four-year-old promises that Altera and Red Hat were working on it.

Go to http://ecos.sourceware.org/ml/ecos-discuss/ and do a search
for NIOS and you'll turn up some links to ports for NIOS and
people working on NIOS-II.

Also, RedHat isn't working on eCos anymore, a while back
they gave up on it, but the people who were working on it
formed a new company called ecoscentric, and it is still
being worked on.

Re: Nios II and eCos - Mustafa - 2004-06-30 22:49:00

Hello Everyone, <br><br>I have a port
of Ecos built under Cygwin using binutils-2.13.1. I build applications that run with this
build of Ecos for the PPC405 (in a VP7) using the EDK (6.2). The application compiles and
runs OK. However, I am unable to debug using Insight under EDK because it generates DWARF
errors when opening the executable.elf file. The problem is that the version of binutils
used by 'xygwin' is 2.11.2 which is older than the binutils used to build ecos.
<br><br>Has anyone had a similiar problem? Several solutions I can think of
are: <br>
1) building ecos with older binutils, though this is not recommended by ecoscentric guys.
<br>
2) building the application under cygwin. I've tried this, though i get a very strange
linking issue. The same linkerscript that works under EDK, generates an empty data segment
under cygwin.  <br><br>Any suggestions? <br><br>Regards,
<br>
Mustafa.
