# Nokia  N900安装Maemo Leste 

Maemo Leste是原官方Maemo Fremantle的后续版，算是继承者。

Maemo Leste 基于 Devuan Beowulf （Debian Buster），所有支持的设备都附带了最新的主线 Linux 内核。Nokia N900适配最新版为maemo-leste-1.0-armhf-n900-20240908.img.xz

从[这里](https://maedevu.maemo.org/images/n900/)下载镜像文件，将下载后的`maemo-leste-1.0-armhf-n900-20240908.img.xz`解压，获得`maemo-leste-1.0-armhf-n900-20240908.img`文件。

Linux下使用`dd`命令将其写入SD卡，Windows下推荐使用Etcher来写入。

### Bootloader (U-Boot) 设置

如果你不想改变现有系统上的`u-boot`配置，或现有系统已经损坏，你可以使用以下方法采取多引导方式来使用  **Maemo Leste**。

从[这里](https://maedevu.maemo.org/images/n900/tools/)下载`0xFFFF`，然后添加执行权限`chmod a+x 0xFFFF`

再从[这里](https://maedevu.maemo.org/images/n900/tools/)下载`u-boot`文件`u-boot-2013.04-2.bin`

关闭NokiaN900，然后在电脑上运行`sudo ./0xFFFF -m ./u-boot-2013.04-2.bin -l`，会出现如下提示:
```sh
bbq@op36:~/下载$ sudo ./0xFFFF -m ./u-boot-2013.04-2.bin -l
0xFFFF v0.8  // Open Free Fiasco Firmware Flasher

```

接下来将NokiaN900连接到电脑，将会自动写入内容。

```sh

打开N900键盘，在电脑上继续输入`./0xFFFF -b`

```sh
bbq@op36:~/下载$ sudo ./0xFFFF -b

然后N900屏幕上即可显示u-boot启动菜单，使用方向键选择外部SD卡中的 **Maemo Leste**即可，首次启动时间可能两分钟左右，请耐心等待。

如果要永久写入`u-boot`，你可以使用`sudo ./0xFFFF -m ./u-boot-2013.04-2.bin -f`来实现。**特别注意这样将替换现有系统fremantle的内核**

### 当前Fremantle系统可用

当前系统正常可用的话，可以按照以下方法来使用 **Maemo Leste**

1. 安装`U-Boot with kernel 2.6.28-omap1`
2. 安装`Linux kernel for power user (boot image for U-Boot)`，此项可选但推荐。
3. 添加 **Maemo Leste** 启动项
```sh
cat > /etc/bootmenu.d/30-maemo-leste.item << "EOF" &&
ITEM_NAME="Maemo Leste"
ITEM_KERNEL="uImage"
ITEM_DEVICE="${EXT_CARD}p1"
ITEM_FSTYPE="ext2"
EOF
u-boot-update-bootmenu
```
4. 在键盘**打开**状态重启N900，键盘**关闭**情况下`u-boot`只引导默认项。
