| Aspeed AST2600 EVB |
| |
| Introduction |
| ============ |
| |
| The AST2600 EVB is an evaluation board for the AST2600 SoC, most |
| commonly used as a Server Management Processor. It includes a |
| Dual-core ARM Cortex A7 processor with DDR4 SDRAM (up to 2GB), SPI |
| flash memory devices for BMC and host firmwares and numerous |
| controllers to drive the server board. |

| How to build it |
| =============== |
| |
| Configure buildroot: |
| |
| $ make aspeed_ast2600evb_defconfig |
| |
| Compile everything and build the rootfs image: |
| |
| $ make |
| |
| Result of the build |
| =================== |
| |
| After building, the output/images directory contains: |
| |
| output/images/ |
| ├── aspeed-ast2600-evb.dtb |
| ├── flash.img |
| ├── image.itb |
| ├── rootfs.cpio |
| ├── rootfs.cpio.xz |
| ├── rootfs.tar |
| ├── u-boot.bin |
| └── zImage |
| |
| Flashing the image |
| ================== |
| |
| To update the contents of the first flash device, copy flash.img : |
| |
| $ flashcp flash.img /dev/mtd0 |
| |
| or simply the boot loader: |
| |
| $ flashcp u-boot.bin /dev/mtd1 |
| |
| Preparing the board |
| =================== |
| |
| * Connect a serial line to the board |
| * Power-up the board |
| |
| Booting the board |
| ================= |
| |
| The AST2600 EVB boots from the SPI flash device directly and loads a |
| first bootloader (usually U-Boot). U-Boot will attempt to load a Linux |
| kernel from the same flash device by default but other storage could |
| be used. |
| |
| * from U-Boot |
| |
| The FIT image image.itb can be used to boot the board from U-Boot |
| using tftp |
| |
| * with QEMU |
| |
| $ qemu-system-arm -M ast2600-evb \ |
| -drive file=output/images/flash.img,format=raw,if=mtd \ |
