SDSPICC26XX driver file post failure

Changjian,

So I may better assist you, would it be possible for you to zip and upload your project?

Derrick

Hi Derrick,
I don't know how to upload my project to forum,Can you tell me?

Hi Derrick,
I think my SPI cfg could be have a problem,because I don't use the DMA and Interrupt, the code as follows

erminal I/O display like this:
Starting the FatSD example
Drive 0 is mounted
Creating a new file "fat:0:input.txt"...Error: "fat:0:input.txt" could not be created.
Please check the Getting Started Guide if additional jumpers are necessary.
Aborting...

Changjian,

When you press reply, you will see an option to "Use Rich Formatting". From there, you will be able to add an attachment via the 'paperclip' icon.

3678.SD_SPI.zip

I have uploaded my project..If you meet a problem when compiling or linking,you can ask me, Thinks for you help again.

Changjian,

Where do you configure the GPIO pins for the SPI Bus? Also, are you remembering to enable the SSI peripheral?

Could you also include your files: SDSPICC2650.c & SDSPICC2650.h?

Derrick

Hi Derrick,
You need to rebuild a path for the project, you can read the readme.txt in folder. I have included the flie: SDSPICC2650.c &SDSPICC2650.h,and SPI is working ,I can see waveform by oscilloscope and the SPI time sequence is right by sending a command.

Changjian,

I am taking a look at your SSPICC2650 files.

In the meantime, are you using a SD BoosterPack? I'd recommend double checking your pin connections.

If you are able to communicate to the SD card via SPI, then you need to ensure that you're following the guidelines set forth by the SD Simplified Specifications. Page 178 is the beginning of the SPI Mode section of this document.

Derrick

Changjian,

Could you try configuring your MISO, MOSI and CLK pins as simply:

Board_SPI0_MISO | PIN_INPUT_EN | PIN_PULLDOWN,
Board_SPI0_MOSI | PIN_INPUT_EN | PIN_PULLDOWN,
Board_SPI0_CLK | PIN_INPUT_EN | PIN_PULLDOWN,

I see your Chip Select pin is being configured in fatsd.c

Derrick

Hello, 

You create the functions and the file SDSPICC2650.c , but you never call its functions. 

This seems strange to me and possibly this is the problem. Did you finally find a solution? 

Hi,
We generally discourage posting a new question to an old closed thread because the person who answered before may no longer be available, and also it will allow whomever is currently assigned to monitor the forum to respond to you more quickly. For these reasons, I suggest you start a new thread with your question and reference this thread.

Thanks

Hello,
yes, i have solved the problem,now the SDSPICC2650 is working wll, my problem is that the pin is not welded well.
