Init does not return error code

[csBlueChip]

MassStorage::Init() does not return its errorcode - so the sketch cannot detect a failure and act accordingly

eg.

int sderr = SD.Init();
if (sderr == SD_MMC_OK) {
  logToFile();
} else {
  serial.print("SD error ");
  serial.printf(stderr, DEC);
  logToSerial();
}

but the change is not obvious because this function

• initialises the media controller
• mounts the media device
• mounts the filesystem
  each of which can produce an error :/

To clarify, it does return a value indicating failure. This request is for the failure reason to be indicated by the return?

https://github.com/JoaoDiogoFalcao/Arduino_Due_SD_HSCMI/blob/master/src/Arduino_Due_SD_HSCMI.cpp#L275 appears to be returning void
But, yes, rather than the core library spamming the serial port [which there is (apparently) no user-friendly way to disable #define Debug(...)], I want to receive back an error code so my program can handle the error condition gracefully.

Regarding the upstream library, you will need to follow up with @JoaoDiogoFalcao. Specifically, you may be interested in JoaoDiogoFalcao#4.

Brilliant. Thank You...
Do we know if the latest version of this library has any "breaking changes"?
If not, is there a specific reason why the Macchina devkit indexes an old version of the library?
..."No breaking changes; No specific reason" would be my preferred answer ;)
