Thank you for quick answer. It seems that something wrong with my PC,
because I successfully instaled it on the another computer. I will try to
copy .dll file to c:\windows\system32 to see what will happen.

Try to copy the DLL into your system32 folder, for example
c:\windows\system32.

Well, I remember that we recently had problems with the caltime sample
(unable to enter anything). It finally worked, but I can't remember how
we fixed it. Definitely not by changing the Nut/OS code.

Hi Harald,
thanks for answering immediately. You're right. The nut/os code looks
much cleaner today than yesterday.. :)
If the modes are properly specified, we end up with two FILE and
NUTFILE mallocs and just one read and write buffer.
ok. next time I'll check twice.
cheers,
Matthias

Hi!
You write you have "MSVSP71.dll" in the Ethernut directory.
I have "msvcr71.dll" in mine. It?s the Microsoft? C Runtime Library
Its also on my C:\windows\system32\ directory
And even if I rename it to "xyz.dll" (in the Ethernut directory) I can
successfully start "nutconf.exe"
Even googling for MSVSP71.dll gave me just 3 hits.
Regard
ernst

Hi Matthias!
Some time ago (still under Nut/OS 3.9.x) I tried to be able to write to the
uart while possibly receiving input chars, but I never received any input,
even when I knew I was sending chars to the rx uart pin.
I did receive the chars as soon as I disabled the output to the uart and did
not open it for write.
However, I did not use stdin/stdout, but two "private" fd's.
Eventually, I gave up and worked around the requirement, but I am still
curious if I did something wrong or if the usart driver is just not ready to
do this.
Regards
Ernst

Betreff: [En-Nut-Discussion] how to assign stdout,stdin and sterr to the
same uart?
hi there
after years of using nut/os, I've just stumbled about a newbie
question/problem.
how do I correctly assign stdout AND stdin to the uart?
the default code in many examples is:
NutRegisterDevice(&devUsartAvr0, 0, 0);
freopen(devUsartAvr0.dev_name, "w", stdout);
so far, that's fine. printf works. But when you call e.g. kbhit() it
never returns as stdin was never assigned.
Browsing the mail archive I've seen people doing it like this:
NutRegisterDevice(&devUsartAvr0, 0, 0);
freopen(devUsartAvr0.dev_name, "w", stdout);
freopen(devUsartAvr0.dev_name, "r", stdin);
this sounds logical, but with the current nut/os code (or the one
from last year..) this is not perfect / probably incorrect.
_freopen first looks for the proper __iob entry and then calls _open
for the given device with the given flags.
the usart on the avr is not written to be opened twice, especially
with different mode flags, everything is reset.
any clues how to do it properly?
cheers,
matthias ringwald

Ernst, you're sure you used the real U(S)ART, not devDebug?
The debug device is typically write-only.

Hi Harald!
I am not sure, and I don?t have the version of the program any more, where I
experimented...
But I remember that during my tests, I found out that devDebug is
write-only.
I will play around with caltime a bit to set my recollection straight on
that..
Thanks & Regards

Thanks Ole For your help,
i have don it in this way (befor you me send a mail back)
i copyed al the files and start the nut os configurator
and selekt the at91sam7s.conf
i selekt the pads for the output files
i kliked in the menu build nut os
he ask me make the pads i say yes
adn then !!!!
i go to the output buld dir and edit \arch\makefile ans deleate the part
/arm/dev/spimmc_at91.c in the file
and let generate the configurator at the end
whit OK
so the problem was solved
but you write me to de-selekt the at91_spi_mmc_access but you can not
disabel this in the configurator or how?
end how can i
Just checkout a new working copy from CVS. You won't need to copy them
over your existing tree. ?
bythe way the cpu and part of the application is now working
i looked fot the pins of the mmc card but at the at91sam7s-EK are not a
memory conector so ...
but in the at91samse ther is i look to it
and you hear from this

Hi Andras,
To make RS485 mode work, you have to setup the uart mode register in
rs485 mode and also enable the peripheral control of RTS pin.
Here is the code I use to set UART0 as RS485 mode.
if(NutRegisterDevice(&DEV_UART0,0,0)==-1)
//open the 485 port
{
//#ifdef DBG
printf("%s Registration failed\n",DEV_UART0_NAME);
//#endif
}
outr(PIOA_PDR, 0x8);
reg_value = inr(USART0_BASE + US_MR_OFF);
outr(USART0_BASE + US_MR_OFF, reg_value | 0x1);

Hi Alain,
I share your opinion regarding Nut/OS vs. Linux, but we both may be a
very small minority. :-)
In fact the SAM9260 is overkill for a tiny system like Nut/OS. On the
other hand, if you want a blindingly fast and tiny system optimized for
a special purpose, Ethernut 5 may easily outperform larger systems
running at higher clock rates. I recently heard about a customer, who
wanted to grab 200 fps from the SAM9 ISI port. It fails, because the
designers simply forgot to add one more register to the ISI/PDC
interface, which would make this possible on Linux. With Nut/OS, this
should still work because of very short interrupt latency times. Image
processing is also my major motivation for Ethernut 5.
I intended to publish a first schematic some weeks ago, but soemhow I
got stuck on the non-trivial power supply options (DC, USB and PoE).
Nut/OS has been successfully implemented on the AT91SAM9260 Evaluation
Kit. You may want to take a look to the Atmel Application Note 'AT91 SAM
Internet Radio'.
Regarding image processing: I purchased a kit from Omnivision, the
OV7720 ECX. It runs quite well via USB, but I do not know, whether this
sensor will work with the AT91SAM ISI. Informations about Atmel's image
sensor interface in the net are rare and I'd appreciate any pointer to
similar projects.

Hi,
Can anyone help me out with how to use the banked memory in the Ethernut 2.
I need an additional 32k to store some structure data.
How do you initialize and use the banked memory?
I remember reading something about the PNut file system some time ago.
Problem is I am already using the XFlash for http pages and I don?t think
you can use both.
Any help would be appreciated.
Thanks Steve

In this particular case, I want to run just one single program! The
speed could be an issue, so with ARM9 am sure it will not be. Also
memory could be more than 256k, so maybe I will have 63Mb just sitting
there heating up the atmosphere...
One stryking point is that from AT91SAM7X266 to AT91SAM9260+SDRAM the
difference is just $5.73 (at digikey's prices)

STR911FM44X6 at digikey: $17.82 and there is none available
STR912FAW44X6 at Mouser: $14.12 (in stock)
Anyway, I don't trust them. And I can say why: A friend of mine worked
at ST (here in Brazil) and he once received an *express* order from the
matrix: DO NOT to loose time with small clients.
I am a small client.

Hi,
Can anyone help me out with how to use the banked memory in the Ethernut
2.
I need an additional 32k to store some structure data.
How do you initialize and use the banked memory?
I remember reading something about the PNut file system some time ago.
Problem is I am already using the XFlash for http pages and I don't
think you can use both.
Any help would be appreciated.
Kind Regards,

hi,
Is there anybody, who used successfully at91sam7x uart in rs485 mode? If I
read the datasheet correctly, I need only setup the uart mode register in
rs485 mode.
(at least on at91rm9200 it's working in this way). I did that, but the RTS
pin isn't toggling as expected.
Another thing is I'm trying to add xyssl lib to the sam7x. Anybody does some
work on it, or has some experience, performace tests?
One more ask, is there anybody who have ported the AHDLC driver to the
SAM7X?
Thanks.
Best Regards,
Andras

Here's a simple API
nut/os/bankmem.c
It's used by
nut/app/playmp3/playmp3.c
The PNUT file system also uses banked RAM
nut/fs/pnutfs.c

Just checkout a new working copy from CVS. You won't need to copy them
over your existing tree.

If you want to disable mmc you could do so in the NutOs configurator
Architecture/Arm/AT91_SPI_MMC_ACCESS
> Have somebody some solutions to fix it?
Yes. I looked into arch/arm/at91_spimmc.c and found the reason:
Line 90:
#else /* MCU_AT91SAM7X256 */
#warning "MMC SPI mode not supported on this MCU"
#endif
Sorry, I do not own a sam7S board, so I can not fix it on my own. But it
should be quite simple. Simply copy the configuration for AT91SAM7X256 a
few lines above. They are
#ifndef MMC_CS_BIT
#define MMC_CS_BIT SPI0_NPCS1_PA13A
#endif
#define MMC_DATAOUT_BIT SPI0_MISO_PA16A
#define MMC_DATAIN_BIT SPI0_MOSI_PA17A
#define MMC_CLK_BIT SPI0_SPCK_PA18A
and modify for your your needs. You will find the correct pins in the
SAM7S datasheet.
If you got it working please send me a patch so I could add it to the
mainline sources.
Bye,
Ole Reinhardt
