What is the size of your pre-created file?

2MB

Probably not how you have described it. All this stuff depends on the size of your SD card and which FAT version you used.

 

How big is your card, which fat file system did you format it as. Do a dir on that file system to show the file you are trying to use.

I tryed with FAT16 and FAT32 , with 1GB and 2GB cards

Did you do a directory listing on the card.. does it list ok including the file sizes?

yes, as i said, everything is working great, i can read the file with success, but when im using the "pf_lseek( ofs)" , with ofs>32768 i got error

hello, a need implement SDCARD interfacing  with MSP430g2553, do i need all this files ?!

Yes, see the first post.

Thread bump.

Please note that Pabigot maintains BSP430 which has an example for the msp430. He also tracks any changes done to the ElmChan library with patches made to the example. Refer this post for more info.

@@Subhrajit Look at @@calinp's Petite FatFS Energia library.

thank to you bluehash and to calinp too.

its working on energia.

actually i am working with micro sd and the breakout board is developed by myself.

and the code or example is working.

 

thank you

are you people work with fpga.

actually my target is to implement it on fpga.

please help me.

My preferred language is vhdl.

This would be a developer request and should not be placed in an active topic.

Short answer: No, we don't do FPGAs, we use MSP430 microcontrollers.

Longer answer: Some of us might know how to use and design FPGAs, but it's not related (directly) to this forum. Why would you want to do this yourself, your FPGA supplier has most certainly an IP block to talk to SD.

Hello fellows,

I can connect the MSP430G2553, width SDcard Chip, I use a LC studio  sdcard and I have made ??all the connections. and ran the program with the Sdcard WRITE.TEXT file saved on the SDcard but nothing happens

I have used this connections:

SDcard----------------MSP430G2553

GND-------------------GND

MISO------------------P1.5

SCK-------------------P1.7

MOSI------------------P1.6

CS---------------------P2.0

3.3V-------------------VCC

What i am doing wrong
