Hi, I currently try to get Petit FS running on MSP430F5529 using USCI B1 and have some problems getting the workspace running. The SD-Card can be accesed and I get response, but I cant get the FS running properly. I have a FAT file system running and I'am able to read the textfile on the SD Card. The problem is that every time I try to write to this file I get an empty file back with no data init. I use R0.08b and my goalis to use the smaller Petit FS with write access to a text file. I used the MSP430F5529 User Experience to get started. Can someone give me a hint where to look for suchan error ? I don't have muchexperience with SD Cards so far so please help me take off.
