sdcard detection

Zakaria Taleb Bendiab

hello

i am working on a project using stm32f205, i am using the file system component v6.6 to
access an sdcard connected to the MCU via SDIO interface.

the sdcard reader i am using dont have card detection switch, so i have to check every time
if the card is present in the reader.

is there any function in the file system component v6.6 that let me do this process.

thanks

    Maybe you can try to reinitialize the card in case this does not happen very often?

    int32_t drive_id = fs_ioc_get_id ("M0:");
uint32_t arg = FS_CONTROL_MEDIA_INIT;

if (fs_ioc_device_ctrl (drive_id, fsDevCtrlCodeControlMedia, &arg) == fsOK) {
  /* Memory media present */
} else {
  /* Memory media removed */
}

    hello

    thanks vladimir for the response.

    i have tried this method but now i have another problem.

    the sdcard is used by the USB MSC thread, and i have to place a semephore
    before checking the card.

    the problem is that i can not found the usb msc task functions.

    thanks
