Add printing a short string in the interrupt code (not the IST) for
insert, and one for remove. Then repeat your insert remove test. You
should see the string(s) match your insert/remove sequence without
being jumbled. If things look jumbled you need to work on your
debouncing code.

Thanks for your replay.But I have consider debouncing the card present
interrupt. Via software and hardware.
It is when card insert/remove ,there is a interrupt.
And if interrupt is happening ,My ISR will receive a event ,and will take a
few seconds(about 1.5 s) for debouncing the card present interrupt.
But "Cannt see SDMMC directory" still happen..

I take it you are using interrupts for detecting card present?
If so you should consider debouncing the card present interrupt. Via
software or hardware.

Dear all
I do some test about SD driver.
I insert SD card and can see SDMMC directory in the root.
Then I unplug and plug SD card fast asap and do a continuous repeat(unplug
and plug) about 10 times.
The SD card is inserted in the device, but cant see SDMMC directory.I check
the log, SD bus driver has loaded SDMemory.dll and process "SMC_Init(DWORD
dwContext)" successful.But I cannt see the SDMMC directory.
Can someone help how to solve or where to check it?
