| Introduction |
| ============ |
| |
| DeveloperBox is a certified 96boards Enterprise Edition board. The board/SoC has: - |
| |
| * Socionext SC2A11 24-cores ARM Cortex-A53 on tbe Mini-ATX form factor motherboard |
| * 4 DIMM slots (4GB DDR4-2400 UDIMM shipped by default) |
| * 1 4xPCIe Gen2 slot and 2 1xPCIe Gen2 slots |
| (1x slots are connected via PCIe bridge chip) |
| * 4 USB-3.0 ports |
| * 2 SATA ports |
| * 1 GbE network port |
| * 1 USB-UART serial port (micro USB) |
| * 64MB SPI NOR Flash |
| * 8GB eMMC Flash Storage |
| * 96boards LS connector |
| |
| The DeveloperBox schematic can be found here: - |
| https://www.96boards.org/documentation/enterprise/developerbox/hardware-docs/mzsc2am_v03_20180115_a.pdf |
| |
| And the other documents can be found here: - |
| https://www.96boards.org/documentation/enterprise/developerbox/ |
| |
| |
| Currently, the U-Boot port supports: - |
| |
| * USB |
| * eMMC |
| * SPI-NOR |
| * SATA |
| * GbE |
| |
| The DeveloperBox boots the TF-A and EDK2 as a main bootloader by default. |
| The DeveloperBox U-Boot port will replace the EDK2 and boot from TF-A as |
| BL33, but no need to combine with it. |
| |
| Compile from source |
| =================== |
| |
| You can build U-Boot without any additinal source code.:: |
| |
| cd u-boot |
| git checkout v2023.07 |
| export ARCH=arm64 |
| export CROSS_COMPILE=aarch64-linux-gnu- |
| make synquacer_developerbox_defconfig |
| make -j `noproc` |
| |
| Then, expand the binary to 1MB for preparing flash.:: |
| |
| cp u-boot.bin SPI_NOR_UBOOT.fd |
| truncate -s 1M SPI_NOR_UBOOT.fd |
| |
| Installation |
| ============ |
| |
| You can install the SNI_NOR_UBOOT.fd via NOR flash writer. |
| |
| Flashing the U-Boot image on DeveloperBox requires a 96boards UART mezzanine |
| or other mezzanine which can connect to the LS-UART0 port. |
| Connect USB cable from host to the LS-UART0 and set DSW2-7 to ON, and turn the |
| board on again. The flash writer program will be started automatically; |
| don't forget to turn the DSW2-7 off again after flashing. |
| |
| *!!CAUTION!! If you write the U-Boot image on wrong address, the board can |
| be bricked. See below page if you need to recover the bricked board. See |
| the following page for more details* |
| |
| https://www.96boards.org/documentation/enterprise/developerbox/installation/board-recovery.md.html |
| |
| When the serial flasher is running correctly it will show the following boot |
| messages printed to the LS-UART0 console:: |
| |
| |
| /*------------------------------------------*/ |
| /* SC2A11 "SynQuacer" series Flash writer */ |
| /* */ |
| /* Version: cd254ac */ |
| /* Build: 12/15/17 11:25:45 */ |
| /*------------------------------------------*/ |
| |
| Command Input > |
| |
| Once the flasher tool is running we are ready flash the UEFI image:: |
| |
| flash rawwrite 200000 100000 |
| >> Send SPI_NOR_UBOOT.fd via XMODEM (Control-A S in minicom) << |
| |
| *!!NOTE!! The flasher command parameter is different from the command for |
| board recovery. U-Boot uses the offset 200000 (2-five-0, 2M in hex) and the |
| size 100000 (1-five-0, 1M in hex).* |
| |
| After transferring the SPI_NOR_UBOOT.fd, turn off the DSW2-7 and |
| reset the board. |
| |
| |
| 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 board the |
| configs/synquacer_developerbox_defconfig enables default FWU configuration :: |
| |
| CONFIG_FWU_MULTI_BANK_UPDATE=y |
| CONFIG_FWU_MDATA=y |
| CONFIG_FWU_MDATA_MTD=y |
| CONFIG_FWU_NUM_BANKS=2 |
| CONFIG_FWU_NUM_IMAGES_PER_BANK=1 |
| CONFIG_CMD_FWU_METADATA=y |
| CONFIG_FWU_MDATA_V2=y |
| |
| And build it:: |
| |
| cd u-boot/ |
| export ARCH=arm64 |
| export CROSS_COMPILE=aarch64-linux-gnu- |
| make synquacer_developerbox_defconfig |
| make -j `noproc` |
| cd ../ |
| |
| By default, the CONFIG_FWU_NUM_BANKS and CONFIG_FWU_NUM_IMAGES_PER_BANKS are |
| set to 2 and 1 respectively. This uses FIP (Firmware Image Package) type image |
| which contains TF-A, U-Boot and OP-TEE (the OP-TEE is optional). |
| You can use fiptool to compose the FIP image from those firmware |
| images. There are two versions of the FWU metadata, of which the |
| platform enables version 2 by default. |
| |
| Rebuild SCP firmware |
| -------------------- |
| |
| Rebuild SCP firmware which supports FWU Multi Bank Update as below:: |
| |
| cd SCP-firmware/ |
| OUT=./build/product/synquacer |
| ROMFW_FILE=$OUT/scp_romfw/$SCP_BUILD_MODE/bin/scp_romfw.bin |
| RAMFW_FILE=$OUT/scp_ramfw/$SCP_BUILD_MODE/bin/scp_ramfw.bin |
| ROMRAMFW_FILE=scp_romramfw_release.bin |
| |
| make CC=arm-none-eabi-gcc PRODUCT=synquacer MODE=release |
| tr "\000" "\377" < /dev/zero | dd of=${ROMRAMFW_FILE} bs=1 count=196608 |
| dd if=${ROMFW_FILE} of=${ROMRAMFW_FILE} bs=1 conv=notrunc seek=0 |
| dd if=${RAMFW_FILE} of=${ROMRAMFW_FILE} bs=1 seek=65536 |
| cd ../ |
| |
| And you can get the `scp_romramfw_release.bin` file. |
| |
| Rebuild OPTEE firmware |
| ---------------------- |
| |
| Rebuild OPTEE to use in new-layout FIP as below:: |
| |
| cd optee_os/ |
| make -j`nproc` PLATFORM=synquacer ARCH=arm \ |
| CROSS_COMPILE64=aarch64-linux-gnu- CFG_ARM64_core=y \ |
| CFG_CRYPTO_WITH_CE=y CFG_CORE_HEAP_SIZE=524288 CFG_CORE_DYN_SHM=y \ |
| CFG_CORE_ARM64_PA_BITS=48 CFG_TEE_CORE_LOG_LEVEL=1 CFG_TEE_TA_LOG_LEVEL=1 |
| cp out/arm-plat-synquacer/core/tee-pager_v2.bin ../arm-trusted-firmware/ |
| |
| The produced `tee-pager_v2.bin` is to be used while building TF-A next. |
| |
| |
| Rebuild TF-A and FIP |
| -------------------- |
| |
| Rebuild TF-A which supports FWU Multi Bank Update as below:: |
| |
| cd arm-trusted-firmware/ |
| make CROSS_COMPILE=aarch64-linux-gnu- -j`nproc` PLAT=synquacer \ |
| TRUSTED_BOARD_BOOT=1 SPD=opteed SQ_RESET_TO_BL2=1 GENERATE_COT=1 \ |
| MBEDTLS_DIR=../mbedtls BL32=tee-pager_v2.bin \ |
| BL33=../u-boot/u-boot.bin all fip fiptool |
| |
| And make a FIP image.:: |
| |
| cp build/synquacer/release/fip.bin SPI_NOR_NEWFIP.fd |
| tools/fiptool/fiptool update --tb-fw build/synquacer/release/bl2.bin SPI_NOR_NEWFIP.fd |
| |
| UUIDs for the FWU Multi Bank Update |
| ----------------------------------- |
| |
| FWU multi-bank update requires some UUIDs. The DeveloperBox platform uses |
| following UUIDs. |
| |
| - Location UUID for the FIP image: 17e86d77-41f9-4fd7-87ec-a55df9842de5 |
| - Image type UUID for the FIP image: 10c36d7d-ca52-b843-b7b9-f9d6c501d108 |
| - Image UUID for Bank0 : 5a66a702-99fd-4fef-a392-c26e261a2828 |
| - Image UUID for Bank1 : a8f868a1-6e5c-4757-878d-ce63375ef2c0 |
| |
| These UUIDs are used for making a FWU metadata image. |
| |
| u-boot$ ./tools/mkfwumdata -v 2 -i 1 -b 2 \ |
| 17e86d77-41f9-4fd7-87ec-a55df9842de5,10c36d7d-ca52-b843-b7b9-f9d6c501d108,5a66a702-99fd-4fef-a392-c26e261a2828,a8f868a1-6e5c-4757-878d-ce63375ef2c0 \ |
| ../devbox-fwu-mdata.img |
| |
| Create Accept & Revert capsules |
| |
| u-boot$ ./tools/mkeficapsule -A -g 7d6dc310-52ca-43b8-b7b9-f9d6c501d108 NEWFIP_accept.Cap |
| u-boot$ ./tools/mkeficapsule -R NEWFIP_revert.Cap |
| |
| Install via flash writer |
| ------------------------ |
| |
| As explained in above section, the new FIP image and the FWU metadata image |
| can be installed via NOR flash writer. |
| |
| Once the flasher tool is running we are ready to flash the images.:: |
| Write the FIP image to the Bank-0 & 1 at 6MB and 10MB offset.:: |
| |
| flash rawwrite 600000 400000 |
| flash rawwrite a00000 400000 |
| >> Send SPI_NOR_NEWFIP.fd via XMODEM (Control-A S in minicom) << |
| |
| flash rawwrite 500000 1000 |
| flash rawwrite 530000 1000 |
| >> Send devbox-fwu-mdata.img via XMODEM (Control-A S in minicom) << |
| |
| And write the new SCP firmware.:: |
| |
| flash write cm3 |
| >> Send scp_romramfw_release.bin via XMODEM (Control-A S in minicom) << |
| |
| At last, turn on the DSW 3-4 on the board, and reboot. |
| Note that if DSW 3-4 is turned off, the DeveloperBox will boot from |
| the original EDK2 firmware (or non-FWU U-Boot if you already installed). |
