[ECOS] ARM SDT & eCos

[ECOS] ARM SDT & eCos

[Niclas Anderberg]

Hello again!

I am one of many, many people who want to use the ARM Multi-Ice to debug
eCos. We have been on the phone with many companies, including ARM
themselves (RedHat is by far the hardest company to get hold of :), and
there are obviously some legal hassles which prevents RedHat from releasing
the multi-ice-gdb-server.exe file. It could be resolved in weeks some said,
but we don't have that kind of time.

So a different solution would be nice. We were thinking of using the ARM SDK
compiler and linker to compile eCos from scratch. In an ideal world this
would work, but my guess is that reality will show otherwise. What i would
like to do is replace the GNU tools with the ARM SDK tools so that I can
debug eCos with the Multi-Ice. Anyone has any experience in this matter, or
enough experience to just give me a flat no?

Thanks in advance

I'd go with the flat no, but I gave up quickly at the time :-)

steps:
	make sure ARM compiler supports init sections and C++ constructer
init stuff (am I right here??)
	re-write all assembler code to use ARM assembler.
	compile and link..

as I said I gave up and bought the EPI Jeeni, if someone else does it I'd
love to see it though..

Dave.

Wiggler from Macraigor is also a much cheaper Jtag Emulator, 
without Ethernet or serial line connection but perfectly functional 
with Insight for base debugging (we own also a Jeeni, and see the 
difference, but as a second buy Wiggler is good). Just take into 
account that the hours spent porting eCOS to ARM SDT will cost 
much more than a brand new Insight-compatible emulator!!!

Just a warning though: I believe wiggler support is going to be removed
from GDB (or perhaps it already has been). This is because of the use of
proprietary DLLs. You'll need to ask on the GDB lists though to be sure.
