I am working on MCB 2300 kit which has got LPC2378 processor. It has got an SD card as well. I can read, write to some text files on the card. But now I want to read some images from SD Card. When i tried to read the images, it gives back some garbage value and then the program gets hang up. I want to read the pixel information of the image. Please let me know how to do it? I am using keil uVision4 IDE

Thanks in advance

You complete your project with MCB2300 board in which you read and write text file.
I try with LPC2368 MCB2300 board for SD card read with keil example but i got every time CARD_UNKNOWN so please help me in reading card code.
I read UM10211 manual chap 20 for SD card interface, but it not give full information for command and argument. Please give proper material link which gives me knowledge of command and argument detail. Advance thanks for cooperate.
