| 6 | DeveloperBox is a certified 96boards Enterprise Edition board. The board/SoC has: - |
| 7 | |
| 8 | * Socionext SC2A11 24-cores ARM Cortex-A53 on tbe Mini-ATX form factor motherboard |
| 9 | * 4 DIMM slots (4GB DDR4-2400 UDIMM shipped by default) |
| 10 | * 1 4xPCIe Gen2 slot and 2 1xPCIe Gen2 slots |
| 11 | (1x slots are connected via PCIe bridge chip) |
| 12 | * 4 USB-3.0 ports |
| 13 | * 2 SATA ports |
| 14 | * 1 GbE network port |
| 15 | * 1 USB-UART serial port (micro USB) |
| 16 | * 64MB SPI NOR Flash |
| 17 | * 8GB eMMC Flash Storage |
| 18 | * 96boards LS connector |
| 19 | |

| 26 | |
| 27 | Currently, the U-Boot port supports: - |
| 28 | |
| 29 | * USB |
| 30 | * eMMC |
| 31 | * SPI-NOR |
| 32 | * SATA |
| 33 | * GbE |
| 34 | |
| 35 | The DeveloperBox boots the TF-A and EDK2 as a main bootloader by default. |
| 36 | The DeveloperBox U-Boot port will replace the EDK2 and boot from TF-A as |
| 37 | BL33, but no need to combine with it. |
| 38 | |
| 39 | Compile from source |
| 40 | =================== |
| 41 | |
| 42 | You can build U-Boot without any additinal source code.:: |
| 43 | |
| 44 | cd u-boot |
| 45 | export ARCH=arm64 |
| 46 | export CROSS_COMPILE=aarch64-linux-gnu- |
| 47 | make SynQuacer_defconfig |
| 48 | make -j `noproc` |
| 49 | |
| 50 | Then, expand the binary to 1MB for preparing flash.:: |
| 51 | |
| 52 | cp u-boot.bin SPI_NOR_UBOOT.fd |
| 53 | truncate -s 1M SPI_NOR_UBOOT.fd |
| 54 | |
| 55 | Installation |
| 56 | ============ |
| 57 | |
| 58 | You can install the SNI_NOR_UBOOT.fd via NOR flash writer. |
| 59 | |
| 60 | Flashing the U-Boot image on DeveloperBox requires a 96boards UART mezzanine or other mezzanine which can connect to LS-UART0 port. |
| 61 | 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. |
| 62 | |
| 63 | *!!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* |
| 64 | |
| 65 | https://www.96boards.org/documentation/enterprise/developerbox/installation/board-recovery.md.html |
| 66 | |
| 67 | When the serial flasher is running correctly is will show the following boot messages shown via LS-UART0:: |
| 68 | |
| 69 | |
| 70 | /*------------------------------------------*/ |
| 71 | /* SC2A11 "SynQuacer" series Flash writer */ |
| 72 | /* */ |
| 73 | /* Version: cd254ac */ |
| 74 | /* Build: 12/15/17 11:25:45 */ |
| 75 | /*------------------------------------------*/ |
| 76 | |
| 77 | Command Input > |
| 78 | |
| 79 | Once the flasher tool is running we are ready flash the UEFI image:: |
| 80 | |
| 81 | flash rawwrite 200000 100000 |
| 82 | >> Send SPI_NOR_UBOOT.fd via XMODEM (Control-A S in minicom) << |
| 83 | |
| 84 | *!!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).* |
| 85 | |
| 86 | After transferring the SPI_NOR_UBOOT.fd, turn off the DSW2-7 and reset the board. |
