PIC32 PINGUIONO's and SD

RE: PIC32 PINGUIONO's and SD
Hi Dale,

I have looked at the PIC32 Pinguino Micro Schematic (Rev_B) and :-
  • the line going to SD/MMC Pin 2 (CD/DAT3/CS) is labelled MMC_#SS
  • the line going to IC Pin 28 (TDI/AN13/PMA10/RB13) is also labelled MMC_#SS
Therefore I would expect SDCS to be associated with Port/Register RB13.
Also
  • the line going to IC Pin 46 (OC1/INT0/RD0) is labelled BUT
  • it it linked via Jumper BUT_J to CON2-3 and IC Pin 52
  • the line going to IC Pin 52 (OC5/IC5/PMWR/CN13/RD4) is connected directly to CON2-3
So there is no indication that IC Pin 46 (RD0) is connected to any of the SD/MMC connections.

Looking at the X.3 r350 digitalw.c file, then I would also agree that IDE P40 = RB13 and IDE P41 = RD0.

I have also checked the past changes to these files and the changes to sdmmc.h occurred around X.3 r317/r318 whereas the inclusion of P41 for the Micro did not come till X.3 r324.

Therefore it does look like for the PIC32 Pinguino Micro SDCS although the comment in the sdmmc.h file is correct the IDE Pin number should be 40 not 41.

For the sake of completeness I would suggest checking the physical connection between IC Pin 28 and SD/MMC Pin 2.

Also for the sake on completeness I also noticed that LED1 (the green LED) is connected to the SCK line, so LED1 should not be addressed directly when the SD card functions are being used. This is the same as on the PIC32 Pinguino OTG board (where it is also connected to D13/IDE P13).

I would say that it is definitely worth trying changing the line in sdmmc.h to read :-
Code:
#define SDCS                            40      // RB13/MMC_#SS Card Select output
and seeing how the PIC32 Pinguino Micro responds.
