Hi.
My code is:
static FX_MEDIA * p_media;
// Wait until device inserted. status = tx_event_flags_get (&g_usb_plug_events, EVENT_USB_PLUG_IN, TX_OR_CLEAR, &actual_flags, TX_WAIT_FOREVER);
// Get the pointer to FileX Media Control Block for a USB flash device p_media = g_fx_media_pd_ptr;
// Retrieve the volume name of the opened media from the Data sector status = fx_media_volume_get(p_media, volume, FX_DIRECTORY_SECTOR);
if (status == FX_SUCCESS ) {
}
The value of status is FX_PTR_ERROR
I do not understand where the cause of this may be. Can somebody help me?
Thank you
The call to fx_media_volume_get() will return FX_PTR_ERROR if either the media_ptr pointer or the volume_name pointer are NULL :-
