Our RTEMS-based project will use micro-SD memory devices to store boot and application images, as well as configuration information files. I am charged with interfacing the hardware to our software, possibly via RTEMS. This is new territory for me, so I am wondering whether people in the community would share their wisdom with me.<br><br>What file systems are appropriate to these devices? <br><br>What are the pros and cons? <br><br>We don't want to infringe on anyone's patents, so probably FAT is out, right? <br><br>Does RTEMS already support something appropriate? <br><br>If not, is it something we should work toward contributing?<br><br>It would be nice if the format is supported by Linux, MacOS and/or Windows, but not strictly required.<br><br>Thanks for any advice you can give me.<br><br> Cheers,<br>
