Re: SDSynchronousBusRequest taking long time

Sorry I was not aware that I could taget multiple groups in "to" field.
Can you suggest me how to go through the debugger? 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.

Why not just step in debugger and see where
it spends so much time?

Also separate cross posting is evil. List all
target groups in "to" field if you want to post
to multiple groups.

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.
