## English
### Created Date
2025/05/15
### Update History
2025/07/11：The new tags `v09.07` now support [runqemu](<https://github.com/AspeedTech-BMC/openbmc/commit/f61b40ac85f6df1517d2f58f2a229b2aa26e8219>). You can directly use the command `runqemu ast2700-default slirp serialstdio` to launch it."
### Environment

### Symptom
None
### Cause
Provide an example of building the AST2700 Evaluation Board (EVB) from the [AspeedTech-BMC/openbmc](<https://github.com/AspeedTech-BMC/openbmc>) project, and running it through QEMU using the [QEMU/aspeed-2700-family-boards-ast2700-evb](<https://www.qemu.org/docs/master/system/arm/aspeed.html#aspeed-2700-family-boards-ast2700-evb>) method for early-stage environment testing.
### Solution
1. Since the AST2700 EVB uses the AARCH64 architecture, please follow the steps in [Installing the latest qemu-system-arm](<https://github.com/ChrisDeng21/daily-record/blob/main/ubuntu/Installing_the_latest_qemu-system-arm_on_Ubuntu_22.04.4_LTS.md#buiild>) to prepare the appropriate QEMU tools.
2. Download the Aspeed OpenBMC source code using the `v09.06` tag as an example.
```shell
git clone -b v09.06 https://github.com/AspeedTech-BMC/openbmc.git
cd openbmc/
```
3. Set up the build environment using the [SDK](<https://github.com/AspeedTech-BMC/openbmc/tree/aspeed-master/meta-aspeed-sdk#create-build-environment>) and configure the target machine as `ast2700-default` to begin compilation.
```shell
. setup ast2700-default
bitbake obmc-phosphor-image
```
- After the compilation is complete, verify whether the images have been successfully generated.
```shell
ls -l tmp/deploy/images/ast2700-default/image-bmc
```
4. Launch the system using the commands provided in [QEMU/booting-the-ast2700-evb-machine](<https://www.qemu.org/docs/master/system/arm/aspeed.html#booting-the-ast2700-evb-machine>).
> Important! Replace `-M ast2700-evb` with `-M ast2700a1-evb`.
```shell
cd tmp/deploy/images/

IMGDIR=ast2700-default
UBOOT_SIZE=$(stat --format=%s -L ${IMGDIR}/u-boot-nodtb.bin)

qemu-system-aarch64 -M ast2700a1-evb \
  -device loader,force-raw=on,addr=0x400000000,file=${IMGDIR}/u-boot-nodtb.bin \
  -device loader,force-raw=on,addr=$((0x400000000 + ${UBOOT_SIZE})),file=${IMGDIR}/u-boot.dtb \

#### Extension
1. If network access to the emulator is required, add parameters to forward the emulator's ports and modify the QEMU command accordingly.
```shell
qemu-system-aarch64 -M ast2700a1-evb \
  -device loader,force-raw=on,addr=0x400000000,file=${IMGDIR}/u-boot-nodtb.bin \
  -device loader,force-raw=on,addr=$((0x400000000 + ${UBOOT_SIZE})),file=${IMGDIR}/u-boot.dtb \
  -device loader,force-raw=on,addr=0x430000000,file=${IMGDIR}/bl31.bin \
  -device loader,force-raw=on,addr=0x430080000,file=${IMGDIR}/optee/tee-raw.bin \
  -device loader,cpu-num=0,addr=0x430000000 \
  -device loader,cpu-num=1,addr=0x430000000 \
  -device loader,cpu-num=2,addr=0x430000000 \
  -device loader,cpu-num=3,addr=0x430000000 \
  -smp 4 \
  -drive file=${IMGDIR}/image-bmc,format=raw,if=mtd \
  -nographic \
  -net nic \
  -net user,hostfwd=:127.0.0.1:2222-:22,hostfwd=:127.0.0.1:2443-:443,hostfwd=udp:127.0.0.1:2623-:623,hostname=qemu
```
> Add two -net parameters after the QEMU command.
> - `127.0.0.1:2222` Port Forwarding for the Emulator `22` (Used for SSH)
> - `127.0.0.1:2443` Port Forwarding for the Emulator `443` (Used for HTTPS/REDFISH)
> - `127.0.0.1:2623` Port Forwarding for the Emulator `623` (Used for IPMI)
2. Alternatively, you can use a script by copying [qemuast2700a1-evb.sh](<https://github.com/ChrisDeng21/daily-record/blob/main/openbmc/qemuast2700a1-evb.sh>) to the root directory of the Aspeed OpenBMC source tree (i.e., under openbmc/). Once the images are successfully built, simply execute the script.
> - Before running the script, ensure that the `QEMUTOOL` parameter specifies a valid tool path. If not, modify it to point to the path where you built your own version.
> 
> - For example: change `QEMUTOOL=qemu-system-aarch64` to `QEMUTOOL=/home/chrisdeng/Work/Project/qemu/build/qemu-system-aarch64`, which reflects my local environment.
```shell
QEMUTOOL=/home/chrisdeng/Work/Project/qemu/build/qemu-system-aarch64
```
> - Also, grant the script execution permission.
```shell
chmod 775 qemuast2700a1-evb.sh
```
> - After that, simply execute the script.
```shell
./qemuast2700a1-evb.sh
```

### 更新歷史
2025/07/11：新的 tags `v09.07` 已經支援 [runqemu](<https://github.com/AspeedTech-BMC/openbmc/commit/f61b40ac85f6df1517d2f58f2a229b2aa26e8219>) ，可以直接使用 `runqemu ast2700-default slirp serialstdio` 指令開啟。

### 症狀
無
### 原因
提供一種範例，編譯 [AspeedTech-BMC/openbmc](<https://github.com/AspeedTech-BMC/openbmc>) 的 AST2700 EVB，並且透過 [QEMU/aspeed-2700-family-boards-ast2700-evb](<https://www.qemu.org/docs/master/system/arm/aspeed.html#aspeed-2700-family-boards-ast2700-evb>) 方式啟動，用於前期環境測試。
### 解決方案
1. 因為 AST2700 EVB 使用 `AARCH64` 平台，請按照 [Installing the latest qemu-system-arm](<https://github.com/ChrisDeng21/daily-record/blob/main/ubuntu/Installing_the_latest_qemu-system-arm_on_Ubuntu_22.04.4_LTS.md#buiild>) 準備適合的 QEMU 工具。
2. 下載 Aspeed OpenBMC 程式碼（以 tags `v09.06` 示範）。
```shell
git clone -b v09.06 https://github.com/AspeedTech-BMC/openbmc.git
cd openbmc/
```
3. 按照 [SDK](<https://github.com/AspeedTech-BMC/openbmc/tree/aspeed-master/meta-aspeed-sdk#create-build-environment>) 建置編譯環境並設定目標機器 `ast2700-default` 來開始編譯。
```shell
. setup ast2700-default
bitbake obmc-phosphor-image
```
- 等待編譯完成後，可以檢查 images 是否正常產出。
```shell
ls -l tmp/deploy/images/ast2700-default/image-bmc
```
4. 按照 [QEMU/booting-the-ast2700-evb-machine](<https://www.qemu.org/docs/master/system/arm/aspeed.html#booting-the-ast2700-evb-machine>) 提供的指令啟動。
> 注意! `-M ast2700-evb` 改成 `-M ast2700a1-evb`
```shell
cd tmp/deploy/images/

IMGDIR=ast2700-default
UBOOT_SIZE=$(stat --format=%s -L ${IMGDIR}/u-boot-nodtb.bin)

qemu-system-aarch64 -M ast2700a1-evb \
  -device loader,force-raw=on,addr=0x400000000,file=${IMGDIR}/u-boot-nodtb.bin \

#### 延伸
1. 如果需要網路連入模擬器的能力，新增轉發模擬器連接埠的參數，將 QEMU 指令改寫成：
```shell
qemu-system-aarch64 -M ast2700a1-evb \
  -device loader,force-raw=on,addr=0x400000000,file=${IMGDIR}/u-boot-nodtb.bin \
  -device loader,force-raw=on,addr=$((0x400000000 + ${UBOOT_SIZE})),file=${IMGDIR}/u-boot.dtb \

> 新增兩行 -net 參數在 QEMU 指令後。

2. 或使用腳本，將 [qemuast2700a1-evb.sh](<https://github.com/ChrisDeng21/daily-record/blob/main/openbmc/qemuast2700a1-evb.sh>) 複製到 Aspeed OpenBMC 程式碼的根目錄下，也就是 `openbmc/` 下，待 images 編譯成功後，直接執行即可。
> - 請先確認腳本內 `QEMUTOOL` 參數所定義的工具路徑是可行的，不然要改成你自己編譯出的路徑。
> 
> - 例如：`QEMUTOOL=qemu-system-aarch64` 改成 `QEMUTOOL=/home/chrisdeng/Work/Project/qemu/build/qemu-system-aarch64`，這是我的環境。
```shell
QEMUTOOL=/home/chrisdeng/Work/Project/qemu/build/qemu-system-aarch64
```
> - 並且賦予腳本執行權限。
```shell
chmod 775 qemuast2700a1-evb.sh
```
> - 之後直接執行即可。
```shell
./qemuast2700a1-evb.sh
```
