Hello,

That patch is working. However many configuration options are not 
implemented, and some part of the assembly startup is absolutly 
unnecessary (Some IT enable part and other absolutly board specific 
code). 

Writing such a port also not a too comlicated method, only a few line 
of code is required.

Are you sure it is not downloadable? (I think i have the original 
patch, and some modification, but I also not implemented the 
configuration related part of it)

I found the patch (I suppose your are talking about) here:
http://bugs.ecos.sourceware.org/show_bug.cgi?id=1000068
I'm having some install problems so if anyone could let me know how 
to properly apply the patch and then build ecos that would be very 
much appreciated.

Hello,

If you have run the patch it created some sub directory.
(I suppose you have run it under the ecosxxx/packages subdirectory)

These directories are practically useless, because the patch is for 
an old ecos version, but you have the platform specific c, and header 
files. 
So create an ashling library under the packages/hal/arm/ and 
copy the contains of the current directory to it. 

After this you have to modify the ecos.db file containing the package 
descriptions. Use the pach created ecos.db file and copy its ashling 
board related content to the original ecos.db file. Don not forget to 
modify the directories part of the package descriptions. You could do 
the same things to the serial driver part of the pach too.

After the modification of the ecos.db use the ecos configuration tool 
and try to use the new ashlig packages. 

If you have different platform than the ashlig board do not forget, 
that the startup part enables one interrupt, and makes the PLL init, 
therefore some modification could be needed in this part 
hal_platfor_setup.h.

Good luck for using the port. If you unable to make it work write me 
an e-mail and I will send you my version of the port. It also not 
100%, because some of the ecos configuration part option is not 
realized, but it is working fine).

Thanks! Installing works fine now. Running is a different thing 
though :( 
I'm trying to get the hello example running. I have a recent version 
of eCos and patched it. Then I build eCos, which goes fine, though if 
I run the tests I get:

/opt/ecos/gnutools/arm-elf/bin/../lib/gcc-lib/arm-
elf/3.2.1/../../../../arm-elf/bin/ld: address 0x400144e4 of /ecos-
c/cygwin/opt/ecos/ecos-2.0/ecos-
work/testashling_install/tests/infra/current/tests/cxxsupp 
section .bss is not within region ram
collect2: ld returned 1 exit status

I guess that's not important because the test is just to big for the 
memory. After that, I build the hello example (with the supplied 
Makefile) and I get two files. hello (86k) and hello.o (1k). I needed 
to convert the files to hex for the flasher to work. Both are 
converted to hex using arm-elf-objcopy, but if I convert hello to hex 
I cannot flash it (the file is to big). Hello can be converted to hex 
and flashed but the board stays dead. I looked into both (bin) files 
with a hex editor and found the following.
Hello.o is very small and only contains the Hello World sample code, 
no OS (I think). Hello contains a lot of data but I guess it contains 
a lot of useless stuff. The first half of the file (except for the 
very beginning) is filled with zero's. I believe we used to open this 
file in GDB -> insight but that doesn't work anymore.
My guess is that I am compiling / linking it wrong or that I 
completely misunderstand something here. Do you have a clue?
Thank you in advance!

Also I am interested in your port, so if you would be willing to send 
it to me I would appreciate it very much!
