Why not just step in de{*filter*} and see where
it spends so much time?
Also separate cross posting is evil. List all

- 1. FTP & WEB server on CE .NET - how to define password?
Hi, I have set up both FTP and WEB server for CE 4.2 image and defined a list of users for the FTP server, but how do I define the password for this user? I have also tried to run the WebAdmin on the CE .NET unit, but access is denied. The following is my Platform.reg settings: [HKEY_LOCAL_MACHINE\COMM\ftpd] "IsEnabled"=dword:1 "UseAuthentication"=dword:1 "UserList"=multi_sz:"windowsce" "AllowAnonymous"=dword:0 "AllowAnonymousUpload"=dword:0 "DefaultDir"=\\windowsce ;Root directory [HKEY_LOCAL_MACHINE\COMM\HTTPD\VROOTS\/BasicOnly] @="\\" "a"=dword:1 "Basic"=dword:1 "NTLM"=dword:0 "dirbrowse"=dword:1 [HKEY_LOCAL_MACHINE\COMM\HTTPD\VROOTS\/NTLMOnly] @="\\" "a"=dword:1 "Basic"=dword:0 "NTLM"=dword:1 "dirbrowse"=dword:1 [HKEY_LOCAL_MACHINE\COMM\HTTPD\VROOTS\/BothAuth] @="\\" "a"=dword:1 "Basic"=dword:1 "NTLM"=dword:1 "dirbrowse"=dword:1 I have it all running when I set the user authentication to false. I have even defined a password in the Control Panel Password and Owner Network credentials but it did not help either. I hope someone can give me a hint on this matter. Thanks, Rolf - 2. web server.how to use adoce3.1 in asp in web server of windows ce4

I created a IST for a GPIO interrupt. Can I do polling and sleep() function inside the IST ? Will the sleep function block other thread ? Is there any size effect ? Thanks, Benson - 5. Internet access problem !
Hi everyone, I am newbie in Windows CE and have to developp an application that will put some files on an FTP server. In fact, my BIG problem is that I can't go on Internet ! I have to be connected over a GPRS modem with serial cable. I use the standard modem configuration of WinCE. I created a new distant connection with the dial number and manage to connect to the server : user authentification is succesfull and i get an IP address. But I can't exchange any datas by IE or even by ping ! I really don't know where the problem comes from ! I work with a PCM-5820 motherboard and WinCE 4.1 tools (eVc and Platform builder). Do I have to include some special features on my platform except RAS/PPP, AsyncMAC & other internet tools ? If someone has already got this trouble, please give me some advice. Thanks in advance, Regards, Julien BACLET

SDSynchronousBusRequest taking long time
by QWR2YWl0 » Wed, 17 Oct 2007 16:40:03 GMT
Hi,
From the SDIO driver we get from Arasan they use SDSynchronousBusRequest()
to issue a bus request to their chip.
We timestamp before and after calling this API, and it takes > 230ms. Why it
takes so long and how can we make it
much faster? The following are the code sample:
SDSynchronousBusRequest(pDevice->hDevice,
SD_CMD_IO_RW_EXTENDED,
argument,
SD_WRITE,
ResponseR5,
&response,
1,
blockLength ,
pBuffer,
0);
where:
argument = BUILD_IO_RW_EXTENDED_ARG(SD_IO_OP_WRITE,
SD_IO_BLOCK_MODE,
pDevice->Function,
wAddress,
SD_IO_FIXED_ADDRESS,
1);
SD_COMMAND_RESPONSE response
Your kind responses are greatly appreciated.

Sorry I was not aware that I could taget multiple groups in "to" field.
Can you suggest me how to go through the de{*filter*}? The code runs on a
Windows Mobile device. Currently I am debugging by writing to a file. I
thought SDSynchronousBusRequest is a call in a library provided by Microsoft.
How can I step through? I am new to Platform builder.
Thanks for your help.

Well, if you have no possibility to debug on the target device
it is getting more complicated. There are not too much things
you can do about it on a ready made WM5 device. Especially because
the bottleneck may be in the lower level sdcard host controller
driver (device specific) and not in the sdbus driver
or sdcard lib (device independent thing). Try different
WM devices, try to analyze sdcard sources, fortunately you have
PB installed. Look here:
...\WINCExxx\PUBLIC\COMMON\OAK\DRIVERS\SDCARD\SDBUS\*
It is definitely worth buying a development KIT if you
want to untie your hands. Try to google around, there
are enough devkits with SDCARD on board and Windows CE
support ...

hanks for the much helpful info. We will follow your suggestions to find the
problem.
Associated with this I have some more questions. The SDIO card we have is
NOT identified by the Symbol M70 running Windows Mobile 5.0 after a reboot.
We have to remove the card and re-insert it back for the OS to recognize the
card and load the driver dll. The registry settings are right as the driver
loads successully when we re-insert the card. So questions are:
1. Are there sources in Platform Builder that I can add some print
statements and find out what is happening during the boot process when the
devices are being loaded?
2. Is it possible to write a EXE that I can run to force load the driver
instead of physically re-inserting the card.

Does M70 recognize any other sdcard after reboot, say sdmemory?
Try turning it off, then insert the memory card and power on.
Is the card detected?

In theory, you can clone sdbus driver/sdcardlib and add some
additional debug output to it. Next you can patch registry
on WM target to load your new sdbus driver instead of original
one. This may or may not work properly, do not forget that
WM is a bit different thing although it is based on CE core.
>> 2. Is it possible to write a EXE that I can run to force load the driver

No, you can't do that. The client drivers get loaded in response
to the slot state change notification initiated by the host
controller driver (which is normally triggered by the card
detection interrupt). Something what you don't have sources for.

es other cards work fine and are recognized after a reboot.
How do I clone the sdbus and sdcard libraries? I was thinking of changing
the source for these libraries and build their libs. Use these libs when I
compile my dll. Will this NOT suffice? Are the sdbus and sdcard libraries a
separate dll in the system?

It is definitely bad idea to modify public sources
in place. Instead copy SDCARD tree to your platform
directory and correct SOURCES files to build from
there. Or you can use sysgen capture tool (I'm not
a big fun of it):
http://msdn2.microsoft.com/en-us/library/aa459163.aspx
Sdcardlib is a statically linked library containing
various sdcard related functions that you are using
in your client driver. While sdbus driver is a true
standalone driver, sdbus.dll or something like that
on WM devices. I pointed you to the sources.

I see the sdbus.dll built in my workspace but when I tried to copy it across
to WM device it says access denied. I cannot even see sdbus.dll in the
\Windows directory BUT when I try to copy it across it shows that the file is
in there and is being overwritten.
Any suggestions on this.

How do you see that? If you are using WM File Explorer
make sure "Show All Files" option is turned on.

I'd suggest you to build the binary using different
file name and then patch registry under:
HKLM\Drivers\Builtin\SDBusDriver
"Dll"="My_SDbus_Driver_With_Debug_Output.dll"

es I have "Show All files" turned on as other dlls show up. Also this dll
does not show up when I connect the handheld to the cradle.
I tried using the SDBus.dll that I built. Changed the filename to SDBus.dll
to SDBus_debug.dll and updated the registry to look at it and rebooted the
device and nothing really shows up after I restart. Does the boot sequence
keep some log somewhere?
Also are you available to help us this problem in person? Are you in Bay

Thanks

No, you can't get any boot log on retail WM device.
That is why I suggested you using a development kit
instead if you want full featured debugging capabilities ...
Keep in mind that some WM devices will not accept
unsigned binaries. You may need to sign your driver
binary first:

If your target is WM devices (at least WM5/6), it makes
sense to look for the boards with Windows CE 5.0 support.
I'd suggest you to pick one initially supported by PB
(have a look at ..\WINCE500\PLATFORM\* directory) to not
additionally pay for the BSP itself, note that some OEMs
will separately charge for the BSP ...
For example, have a look at SMDK2410 and Mainstone.
Both are including SDCARD support and both are natively
supported by CE.
If you have in mind playing with different interfaces
as well (not only SDCARD) make sure they are all
included/supported by the dev kit and BSP.
Here you can find some more boards with Windows CE
support:
http://msdn2.microsoft.com/en-us/embedded/aa714506.aspx
Just keep in mind that getting an embedded OS running
is not a 5 min job. You may need to dig a bit deeper
into various building/configuring etc aspects...
