Assuming you're using a news reader, try refreshing your newsgroup list --
that worked for me.

Hi,Martin

First of all, I apologized for my precipitance.
Please allow me to ask you a question which is irrelated to this
post.
--------------------------------------------

I found your post in
http://groups.google.com/group/microsoft.public.windowsce.platbuilder/browse_thread/thread/420dd6c26470188c/991b3d22ffebe6c1?lnk=gst&q=com16550.dll&rnum=6&hl=zh-CN#

you said that I have ported the 16550 driver from MS to my ARM9
Platform (Mutiple UART EXAR 16C554) and it works fine.

I am doing the same work,but I have some problems.
===================================
I have a arm development baord(s3c2410 + wince5.0) with a ST16C550.
nGCS1 is connected to ST16C550's CS2 pin.EINT13 is connected to
ST16C550's INT pin.

I had did the following works:
1) nGCS1 is bank1,It's physical address is 0x0800_0000 . I found "DCD
0x82000000, 0x08000000, 32 ; 32 MB SROM(SRAM/ROM) BANK 1" in the
map.a(PLATFORM\SMDK2410\KERNEL\HAL\ARM\map.a),so I write
"IoBase"=dword:82000000 ; in platform.reg(this is virtual address
after mmu,is that right?)
2) I added following code in cfw.c(platform\smdk2410\kernel\hal
\cfw.c)
2.1)in OEMInterruptEnable function:
case SYSINTR_16550:
s2410IOP->rEINTPEND = (1<<13);
s2410IOP->rEINTMASK &= ~(1<<13);
s2410INT->rSRCPND = BIT_EINT8_23;
if (s2410INT->rINTPND & BIT_EINT8_23) s2410INT-

>rINTPND = BIT_EINT8_23;

s2410INT->rINTMSK &= ~BIT_EINT8_23;
RETAILMSG(1,(TEXT("::: SYSINTR_COM4
OEMInterruptEnable\r\n")));
break;
2.2)in OEMInterruptDisable function£º
case SYSINTR_16550:
s2410INT->rINTMSK |= BIT_EINT8_23;
s2410INT->rINTSUBMSK |= (1<<13);
break;
2.3)in OEMInterruptDone function£º
case SYSINTR_16550:
s2410INT->rINTMSK &= ~BIT_EINT8_23;
s2410IOP->rEINTMASK &= ~(1<<13);
break;
3) I added the following code in arminit.c
in OEMInterruptHandler function:
else if (IntPendVal == INTSRC_EINT8_23) // EINT8 ~ 23
{
// ...............
if ( submask & (1 << 13))
{
s2410IOP->rEINTMASK |= 0x2000;
s2410IOP->rEINTPEND = 0x2000;

s2410INT->rSRCPND = BIT_EINT8_23;
if (s2410INT->rINTPND & BIT_EINT8_23)
s2410INT-

>rINTPND = BIT_EINT8_23;

RETAILMSG(1, (TEXT("INT:SYSINTR_16550
INT..........\r\n")));
return SYSINTR_16550;
}
// ...................
}
4) I add the code "#define SYSINTR_16550 (SYSINTR_FIRMWARE+20)" in
PLATFORM\SMDK2410\inc\oalintr.h
5)the code in platform.reg:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\SERIAL4]
"DeviceArrayIndex" = dword:3
"SysIntr"=dword:24 ;SYSINTR_FIRMWARE+20 = 16 +20 = 36 =0x24
"Irq"=dword:14 ;20 = 0x14
;"MemBase" = dword:08000000
"IoBase" = dword:08000000
;"MemLen" = dword:10
"IoLen" = dword:2C
"Prefix"="COM"
"Dll" = "Com16550.Dll"
"Order"=dword:0
"Index"=dword:4
"Priority"=dword:0
"Port"="COM4:"
"Tsp"="Unimodem.dll"
"DeviceType"=dword:0
"FriendlyName"="Serial Cable on COM4:"
"DeviceConfig"=hex:10,00, 00,00, 05,00,00,00, 10,01,00,00, 00,4B,
00,00,00,00,08,00,00,00,00,00,00
"IsrDll" = "isr16550.dll"
"IsrHandler" = "ISRHandler"

;[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Serial4\Unimodem]
; "Tsp"="Unimodem.dll"
; "DeviceType"=dword:0
; "FriendlyName"="Serial Cable on COM4:"
; "DevConfig"=hex: 10,00, 00,00, 05,00,00,00, 10,01,00,00, 00,4B,
00,00, 00,00, 08, 00, 00, 00,00,00,00

============================
I build the nk.nb0 and download it to board. and , see the COM4 in
<ACTIVE> key.

But when I send data,the program hangs after WriteFile function.The
dwBytesWritten is 0.

When I read data from com4,the return value of ReadFile is 1,but
dwLength is 0.

Sorry for my poor English.

Pls help me .

1/ Are these settings in flatform.reg ,such as,

"IoBase" = dword:08000000 ;or mmu virtual address dword:82000000 ??

right?

Maybe you can show me your code in platform.reg about these settings?

2/ Anythings that I missed or mistaked?

Thans a lot^_^

You can reply after my post or maybe you can give me a email.

Hi Colin:
We just have one TV Tuner card which to receive Digital TV through USB, and
the driver is BDA driver. What is 'non-BDA tuner card' exactly?
BTW, I have download the latest WDK pakage and installed the DTM again, but
not any TV Tuner cases offered nither?

In addition to the (digital) TV tuner you are trying to test, you need
another tuner card e.g. an old analogue tuner. I don't have full details on
the bug, but as I understand it, it has to be a driver which does not use
BDA interfaces i.e. one with a proprietary API - then DTM will find the card
you *do* want to test! As I said, I use an old (approx 3-4 yrs) Pinnacle PCI
card, and that corrects the problem.
There is no fix available yet for this bug - I'm told there will be a new
version of DTM soon which its claimed will fix it.
