RE: [ECOS] which gcc toolchain to use ?

[Harsha D]

Gary,

As i said earlier ... my redboot hangs in do_version.  (at the place
where the RAM range is printed).
I thought may be optimization flag was playing around..(as was in the
case of v4.0).  So just tried 
removing it.

Even then how can optimization flag effect the working of redboot as a
whole ? 


Andrew, 

I just went around looking for the toolchain and i came across this "
... some problems with gnu 
tools on cygwin... ecos on cygwin is not supported... "

And Now i have this doubt "Development on cygwin?" or "Development on
linux?".  Although i am 
more comfortable working on windows, i would definitely like to avoid
extra work needed (if its 
the case) to make it work using cygwin.


regards
hasha

I've also had good luck with 3.4.3.  However, I never build
without optimization (why would you want to?)

The toolchain available for download from the eCos site works OK on
cygwin. The configtool has problem with modern versions of cygwin. To
fix that you want to use a recent snapsnot. You can download that from
www.ecoscentric.com, from the DevZone section, or just use the CLI
tool, ecosconfig.

Having said that, i beleave most of the maintainers use Linux as there
host platform. Its generally just less hassle. Also, using the
synthetic target is very useful and it is Linux only.

[ECOS] "Fis init" failed on EB40A

[Jaws]

Hi all,
    I have some problem with flash and fis commands.
I' using the EB40A with the redboot versio

RedBoot> version

RedBoot(tm) bootstrap and debug environment [ROM]
SRI release, ATMEL bootstrap v2.20 - built 11:05:22, Mar  6 2002

I wonder if it could be the flash bug mentioned in atmel erratas.
Is CYGHWR_DEVS_FLASH_ATMEL_AT49XXXX_ERASE_BUG_WORKAROUND set
in the at49 flash driver cdl?

Did it come to your mind that there might be a major difference between 
EB40 and EB40A?

EB40A is not supported in ecos 2.0, you have to use cvs.

Re: [ECOS] "Fis init" failed on EB40A

[Jaws]

Hi Dirk,
i know the difference beetwen the two platforms, but i don't know why the
atmel provide the redboot with the version string "EB40" on the directory
EB40A. So the dubt could be an error on the version string or ont hte
directory name. Anyway the EB40A is supported on ecos 2.01 infact the
redboot image build for my platform is compiled from that version and the
EB40A template exist in it.
My problem is that when I run the RAM version of my redboot on EB40A,
everithing works fine, also the fis init comamnds and so on, But when i
tried to launch the ROM or ROMRAM version the result is the same:

$T0a0f:a08c0202;0d:eccf0e02;#71
$T0a0f:a08c0202;0d:eccf0e02;#71
$T0a0f:a08c0202;0d:eccf0e02;#71

for each time I pressed Enter. i supposed it was a problem related to a
change in the serial baudrate, but I tried different rate with similar
output but nothing related to redboot prompt.

any idea about this?

Thanks
Jaws

No, this message tells you that RedBoot got an error, probably within
the FLASH access code itself.  In this case the code was executing
at location 0x02028CA0 - you can look this up in your ROM .elf image.

What you see is GDB strings which indicate the failure.  Unless you
connect with a GDB client, you won't be able to make much sense of them.
If you type characters, it will just spit out the same string (unless
you know how to type GDB internal protocol!)

Are you running with the two halves of the flash swapped? I'm not sure the
driver is smart enough to deduce that.

Re: [ECOS] "Fis init" failed on EB40A

[Domenico La Fauci]

Hi Paul,
    sorry but I don't understand what you said. Could you please explain me?
Now I have a new version of Redboot for EB40A that works with all of fis
commands.
The problem that I have now is that the RAM version of redboot works
properly but the ROM or ROMRAM version doesn't start. when the board is
powered up led D1-D5 are on but no communication the serial line.

When I tried to load the ROM version in RAM and launch it, this is the
result:

RedBoot> fis lis
Name              FLASH addr  Mem addr    Length      Entry point
RedBoot           0x01000000  0x01000000  0x00020000  0x00000000

RedBoot>

This will not work. eCos is position dependant. The ROM version is
linked so that it runs at the address location the ROM is at. 

Another thing a ROM version might do is setup the RAM controller. With
most processors, setting up the RAM controller when running in RAM
will cause a crash.

So if you want to run the ROM version you need to put it into ROM. I
suggest you have a JTAG flash programmer handy. If your ROM image does
not boot you have a dead board which you can only recover using the
programmer.

Re: [ECOS] "Fis init" failed on EB40A

[Jaws]

Thanks Andrew,
    I did also this test with  JTAG programmer but the ROM or ROMARAM
version doesn't work.
The board remains blocked. I don't understand why the RAM version work
properly and the ROm version doesn't.
Could be a problem related to the startup? How can I investigate this
problem?

Thanks

I've also had good luck with 3.4.3.  However, I never build
without optimization (why would you want to?)

See:

Get the toolchains from there. They are known to work well.

[ECOS] which gcc toolchain to use ?

[Harsha D]

Hi

I have been trying to port ecos on ARM9 based board.
I tried with gcc v4.0 (cygwin) and gcc v3.4.3


In my case i have observed that

in v4.0 > 
	Removing optimization(O2) flag... redboot works
	Including optimization flag... redboot fails 

in v3.4.2	>
	Removing optimization flag... redboot FAILS
	Including optimization flag... redboot works


also....redboot seems to hang at do_version, printing the RAM range.


I would like to know which is the best/suitable gcc toolchain to be used
with eCos


regards
harsha
