+Enable FWU Multi Bank Update +============================
+DeveloperBox supports the FWU Multi Bank Update. You *MUST* update both *SCP firmware* and *TF-A* for this feature. This will change the layout and the boot process but you can switch back to the normal one by changing the DSW 1-4 off.
+Configure U-Boot +----------------
+To enable the FWU Multi Bank Update on the DeveloperBox, you need to add following configurations to configs/synquacer_developerbox_defconfig ::
- CONFIG_FWU_MULTI_BANK_UPDATE=y
- CONFIG_FWU_MDATA_MTD=y
- CONFIG_CMD_FWU_METADATA=y
- CONFIG_TOOLS_MKFWUMDATA=y
+And build it::
- cd u-boot/
- export ARCH=arm64
- export CROSS_COMPILE=aarch64-linux-gnu-
- make synqucer_developerbox_defconfig
- make -j `noproc`
- cd ../
