Add the DeveloperBox 96boards EE support. This board is also known as Socionext SynQuacer E-Series. It contians one "SC2A11" SoC, which has 24-cores of arm Cortex-A53, and 4 DDR3 slots, 3 PCIe slots (1 4x port and 2 1x ports which are expanded via PCIe bridge chip), 2 USB 3.0 ports and 2 USB 2.0 ports, 2 SATA ports and 1 GbE, 64MB NOR flash and 8GB eMMC on standard MicroATX Form Factor.

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: -

|
||
|
||
|
||
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.
