    Can you reflash a STR9 part in circuit via a SD/MMC card ?

    We would like to do this so we can program our device

    in the field with a PC.

    It is possible, an example would be to use bank1 as a bootloader.

    This would then read the sdcard when inserted, and write contents of a file into bank0 flash.

    efs is a good place to start for an embedded file system:

    http://sourceforge.net/projects/efsl

    we have just used this in a mp3 project, the str9 sdcard port will be sent to efsl very soon.

    Regards

    I have made a test build of EFSL for BANK1 and I have space problems. My ARM Flash release is about 30,5kB and i must write the bootloader application.

    Should i write my own functions rather than STstdlib or should I try to minimize EFSL?
