# Concerning the FFS, there is one fundamental difference between the gtamodem # and pirelli targets: whereas the content of Openmoko's modem FFS is directly # fit for reuse by our fw (resulting from the phylogenetic proximity of the two # firmwares), Pirelli's original FFS has the same format, but its content is so # different that trying to reuse it would be more trouble than it is worth. # (And Pirelli's FFS contains no IMEI or RF calibration data to boot!) # # Therefore, I (FC developer Michael Spacefalcon) have decided that when # targeting the Pirelli, it would be better for us to start from our own blank # FFS than to deal with the original. This feature pirhack-ffs configures our # GSM fw to put its FFS in the last 7 256 KiB sectors of the 2nd flash chip # select: these sectors form an independent read/write bank, and are not used # for FFS by Pirelli's fw, eliminating the possibility of accidental FFS # cross-contamination between the two very different firmwares on the same hw. # # If you want to use some other sectors for FC FFS on the Pirelli, invoke # feature pirhack-ffs first, then change CONFIG_PIRHACK_FFS_START and # CONFIG_PIRHACK_FFS_NBLOCKS to taste. if [ $TARGET != pirelli ] then echo \ "Error: feature pirhack-ffs is applicable only to target pirelli" 1>&2 exit 1 fi FFS_IN_RAM=0 CONFIG_PIRHACK_FFS=1 CONFIG_PIRHACK_FFS_START=24 CONFIG_PIRHACK_FFS_NBLOCKS=7 CONFIG_FLASH_WRITE=1 export_to_c CONFIG_PIRHACK_FFS export_to_c CONFIG_PIRHACK_FFS_START export_to_c CONFIG_PIRHACK_FFS_NBLOCKS export_to_c CONFIG_FLASH_WRITE
