- 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
- export ARCH=arm64
- export CROSS_COMPILE=aarch64-linux-gnu-
- make SynQuacer_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 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 failed to 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 detail*
- https://www.96boards.org/documentation/enterprise/developerbox/installation/board-recovery.md.html
- When the serial flasher is running correctly is will show the following boot messages shown via LS-UART0::
- /*------------------------------------------*/
- /* 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.
