[ECOS] Problem with Config Tool on Cygwin

[ECOS] Problem with Config Tool on Cygwin

[Tom Smithkowski]

Hello,

I'm new to eCos, and trying to get the Configuration Tool running. I'm
running the latest Cygwin on WinXP Pro SP2.

I initially had the problem noted below.

I have since tried the patched version from eCosCentric, but instead
of exhibiting the same problem, I'm getting an abort with a stack dump
(see attachment).

Is anyone else seeing this problem, and are others able to
successfully run the Configuration Tool with the latest Cygwin?

Thanks,

- Tom

You need a more recent build of the eCos Configuration Tool for use with
Cygwin 1.5.10 and later. Ref:

I will investigate this issue. Please raise a bug report at
http://bugs.ecos.sourceware.org/ which includes the versions of the
Cygwin DLL and tcltk libraries you are using:

  cygcheck -c | egrep cygwin\|tcltk

I can now confirm that there is a problem with the eCos Configuration
Tool and version 1.5.19 of the Cygwin DLL. The eCos Configuration Tool
fails during initialisation inside a call to pthread_key_create():

This looks similar to the issue discussed at:

  http://www.cygwin.com/ml/cygwin-patches/2006-q2/msg00065.html

As a workaround, it is currently possible to revert to version 1.5.18-1
of the "cygwin" package using the Cygwin Net Release Setup Program.

Since the probable cause of this issue has been identified and patched,
I will wait for a new release of the Cygwin DLL before investigating any
further.

Thank you for investigating this issue. Just to make sure I am
understanding correctly, your conclusion is that this is due to a
cygwin bug, and that you would expect that to be fixed in a future
release. Therefore, no changes to configtool are required at this
time.

I'll try with an older cygwin version and post again if by chance it
is not working.

Thanks again,

- Tom

That is my hypothesis, yes.

Hi John,

So is this the same issue as:

Thanks,

[ECOS] eCos & RedBoot on AT91SAM7S

[Evgeny Belyanco]

Hi!

If I will write RedBoot image to AT91SAM7S256 (for example)
http://ecos.sourceware.org/ecos/boards/at91sam7s.html

will I be capable of writing code to FLASH via GDB (RS-232
connection)?

Can I make debugging in FLASH via GDB (RS-232 connection)?

Which version of GDB should be used?

Using gdb, no. You need to use redboot itself to do an xyzmodem load
into flash.

You cannot have break points, or single step. So this makes it very
hard to do anything useful.

The only practicaly way to debug code in Flash is over the jtag
interface.

If I will use simple JTAG tool, for example Macraigor usb2Sprite™
http://www.macraigor.com/usb2sprite.htm
will I can make FLASH write, break points, or single step in
AT91SAM7S?

Or I need only "serious" JTAG tool like PEEDI for this features?

I've never used the MacGraigor tools.

Does anybody successfully use Macraigor tools for complete JTAG (LASH write, break
points, or single step) debug ARM MCU with embedded FLASH?

RE: Re[2]: [ECOS] eCos & RedBoot on AT91SAM7S

[Laurie Gellatly]

Hi Evgeny,
I'm using the sprite with a phyTec2294 board with an ARM7.
I use the Philips Flash Utility LPC200 to load the flash (actually I
have to do that thru 'flash buffer operations' as the front screen
didn't work for me).
Using the OCD commander I've been able to single step thru the flash
code (took some efforts to get thr right config :endian and speed), but
its pretty slow. Trying to use it thru GDB/insight remotely partly
works. It does not like setting break points or single stepping in
flash.

Good luck.                ...Laurie:{)
