I think you need /file, not \file

Thanks... Embarassed

Suggests you are trying to talk to the card too quickly at boot. There is an initialisation time specified in the SD documents, that they require before they can start. The demo code does a print befo ...

OK. It was just that it could wake up in the wrong mode otherwise....

I really think you need to triple check the connections.

Working now, just did :

Do you have the required resistors on the SD connections?.

Ideally 10K pull-ups on SCK, SDO, SDI, and SDCS.

The SCK one is only to speed the rising edges (you can get away without this), The SDI ...

Sorry, I made some undocumented changes, this is my new code:

#include <main.h>

#define MMCSD_PIN_SCL PIN_B11 //o
#define MMCSD_PIN_SDI PIN_B13 //i
#define MMCSD_PIN_SDO ...

Just using mmcsd.h and trying to do a mmcsd_init() will keep on giving me timeout. I'm totally clueless right now, any ideas?

I've got the lines pulled up, I'm using a 3v uC and I'm still getting n ...

Ok, here it is:

Have you actually tested that you have the sector read and write working on the device?.

Fat_init, calls the mmcsd_init. This does the speed changes to switch the device up to the faster SPI clock. ...

Hello again Smile

, things got really busy and I couldn't work on this project, but I'm back on it :D.

It seems the program keeps looping at fat_init();

If I comment this line here:

#use ...

Whoa.

Your way of 'fixing' it, means you can be writing to an undeclared area of memory. It'll compile, but won't necessarily work.....

Problem is that:

File *file_stream;

Means that 'file ...

Fixed:

Added the line

#device PASS_STRINGS=IN_RAM

after the #include <33EP512GP504.h>

and changed the declaration of
FILE file_stream;

to
FILE *file_stream;

One warning. In the code library you will find three threads, including an SDHC modification, and a couple of fixes for faults in the standard SD driver. There is then an 'accrued' version at the star ...

The point is that you shouldn't have to be doing this, as I said, contact CCS.

Will do! Smile

well first place to look is in the 'code library' here...
