Hi,
ADS CE 3.0 has a build in CIO1: driver and CIOtest program as a example howto access to the Ethernet controller LAN911C.
Since I upgrade to CE.NET 4.12, I can not open the CIO driver to access the LAN911c registers because the CE.NET doesn't have CIO driver.
1. Which driver in CE.NET has the same function like CIO driver in
CE 3.0 to access the LAN911c controller ?
2. Does it have the CIOtest program for CE.net ?
3. Is the LAN911c address map change in CE.NET 4.12 ?
Best Regards.
Nghia.

Hi Nghia:
As we discussed earlier this week, we're phasing out the WinCE CIO1: driver in favor of the faster CF driver library we've recently developed. You can find that driver posted at topic 845.
While it will take a few minutes to convert your code over to the new driver format, I think you will find the performance improvements well worth your while. Let us know how it goes! |

Hi Drew,
It doen't work on my ADS development system running CE 4.12 ( BitSy Plus). I compile with eVC++ 4.0
The following message is a debug output:

I discussed this problem with Nghia and it turns out that he had nothing in the PCMCIA slot when he ran the test.
As the header of the application code states, this test writes to the PCMCIA slot and then reads back the same address for comparison. This works only if there is a card in the slot and the Memory space is writeable (i.e. an SRAM card). |

Hi Chis,
We buy a new CF memory and insert into a PCMCIA Slot and run the ReadPCMCIA application. I get the folloeing result:
1.EthernetDetectThread: OK.
2.ReadWriteTestThread : Fail.
3.ReadOnlyTestThread : Fail.
DEBUG output:

2. Beside that I integrated the MappAddress(..) function into my CPcmciaCF C++ class as follow:
LPVOID CPcmciaCF::MapAddress(DWORD dwPhyBaseAddress)
{
DWORD LastError = -1;
LPVOID pAddr = (DWORD *)VirtualAlloc(NULL, MEMORY_SIZE, MEM_RESERVE, PAGE_READWRITE);
if(pAddr)
{
RETAILMSG(1, (_T("Virtual Alloc OK\r\n")));
if(VirtualCopy (pAddr, (LPVOID)(dwPhyBaseAddress >> 8), (DWORD)MEMORY_SIZE,
(DWORD) PAGE_PHYSICAL | PAGE_READWRITE | PAGE_NOCACHE) )
{
//RETAILMSG(1, (_T("Virtual Copy OK\r\n")));
byBaseAddress = (BYTE *) pAddr;
wBaseAddress = (WORD *) pAddr;
dwBaseAddress = (DWORD *) pAddr;
RETAILMSG(1, (_T("0x%08x mapped to: 0x%08x\r\n"), dwPhyBaseAddress, byBaseAddress));
}
......
and it executes "VirtualAlloc" and "VirtualCopy" without error, but if it executes the
" byBaseAddress = (BYTE *) pAddr;"
line code then the LCD screen is blank ( all Icons are disappeared)
unless I have to eject the PCMCIA adapter.
My question is: Did I do something wrong here ?
1. I run BitSy Plus ADS development system wit CE.NET 4.12
2. I run eVC++ 4.0 with SP1 on PC under Win2000
3. ActiveSync 3.6.
Thanks for your advice.
Nghia.

Nghia,
Is this a RAM card or an ATA filesystem card? The ReadWrite test will only work if the card has writable Memory space. If you're using an ATA card, then you should try the ReadOnly test.
The device "hanging" when you run the code sounds like the CARDB_WAIT signal is telling the CPU to go into a wait state. The line of code you state causes the hang should have no effect on the system as you are simply assigning a variable to the allocated memory's base address. Are you sure this is where is halts?
Also note that the ADSCF2 source does not have this code. Is there a reason you aren't simply using the ADSCF2 source files as-is?

Chris,
It is a ATA Card but I did use the ReadOnly option (see the debug output).
I guess that after make a execution "VirtualAlloc" and "VirtualCopy" (without error return) the system assign the memory address "out of range"(?) because after I reject the PCMCIA card the Windows CE.NET 4.12 pop up the error message:
"Application Lan91C_4.exe has performe dan illegal
operation and will be shut down.If problem persists,
contact the program vendor.
Program: Lan91C_4.exe
Exception: 0xc0000005
Address: 00013564 "
and with the remote dedug tools I do not find the address location 000013564.
and on the PC I get the error message:
" You can not continue debugging
The platform Manager server is not available
You must stop debugging, exit EVC.EXE, and restart.
OK
"
Is is possible that System returns the invalid address from VirtualAlloc and VirtualCopy functions ? or
do I configure something wrong in my system setup ?
Thanks.
Nghia.

Hi
I am having problems writing to the Board. The read seems to work as I can see the data value change . But when I write & then read. I do get my expected values. I am not sure as to how only write can fail.
(Or is that both are failing??)
BTW, I am trying to write to registers on a board connected using through the CF Interface. I am using the SLOT1_IO_ADDR for MapAddress()
Any Suggestions
Thanks |
