Hello Everyone, We are working on a simple data logging application using MSP-EXP430F5529 and Ez430-RF2500 devices using mspgcc. Thanks to excellent resources and this forum, everything is working fine. I had a simple question about SD-Card write. Our application writes a data packet to SD-Card as soon as it receive on EXP board. The packet size is 40Bytes and may increase more. The binary data is stored in files on SD card which we later run through our interpreter. Now if someone pulls the SD-Card in midst of write operation what will happen? I wanted to ask - is it possible that portion of data packet may be written to file when SD card is suddenly pulled out? Because if this happens the whole series of binary data will not make any sense or may give us totally wrong information. If this happens how do we handle it? Is there a way to make this write operation atomic?? -- View this message in context: http://msp430-gcc-users.1086195.n5.nabble.com/A-question-about-SD-Card-write-on-MSP-EXP430F5529-tp6710.html Sent from the MSP430 gcc - Users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
