hi bkucera,

you could use u-boot to load your application image from the cf card. u-boot supports a variety

of filesystems -- including fat. this would allow you to essentially drag 'n drop on the development

Thanks for the fast response. Can u-boot handle hardware as well as software updates? With the flash programmer you can write an SOF file as well as your software into flash.

Also is there any issue with multiprocessor designs? Right now my design is dual processor, with one cpu running code under the uC-OS and the other running a standalone program.

One more question: Is the idea of copying SOF/program data from the CF card to the onboard flash valid? At this point that seems like the easiest way to go, at the expense of the flexibility that u-boot provides.
