Description:

After calling FFat.begin(), doing some file work and then FFat.end(), subsequent calls to FFat.begin() always fail.

Way to reproduce:

Open the included FFat_Test example. Confirm it works (don't forget to use a partition scheme with a FAT partition). Then, on setup() around line 163, replace the following block:

    if(!FFat.begin()){
        Serial.println("FFat Mount Failed");
        return;
    }
    Serial.printf("Total space: %10lu\n", FFat.totalBytes());
    Serial.printf("Free space: %10lu\n", FFat.freeBytes());
    listDir(FFat, "/", 0);
    writeFile(FFat, "/hello.txt", "Hello ");

with this one:

    if(!FFat.begin()){
        Serial.println("FFat Mount Failed");
        return;
    }
    Serial.printf("Total space: %10lu\n", FFat.totalBytes());
    Serial.printf("Free space: %10lu\n", FFat.freeBytes());
    listDir(FFat, "/", 0);
    FFat.end();
    delay(5000);
    if(!FFat.begin()){
        Serial.println("FFat Mount Failed");
        return;
    }
    writeFile(FFat, "/hello.txt", "Hello ");

The second FFat.begin() returns false. and "FFAT Mount Failed" prints on serial. If debug is enabled, the following message appears.

Yup. I'll take a look.
