Hi,

How do you verify the reported capacity?

At hal_sdc.c :

Code: Select all

  else {
    /* The card is an SDC, capacity from the normal CSD.*/
    sdcp->capacity = _mmcsd_get_capacity(sdcp->csd);
  }

I'm illiterate at SD Card code, so may be it's not the way to check it

[Giovanni]

Could you try another card? is the capacity still wrong? if so then there could be a bug there.

With a 8GB card, it reports 15.130.624, with a 64GB, it reports 122.138.624 and with a 256MB, 491.520

I have checked on a PC, and the reported capacity by Chibios is correct, although it's in number of sectors of 512 bytes; that's the reason I saw half the capacity

[Giovanni]

Ah OK, it is the number of available blocks
