我想用shell构建自定义Linux内核。我的硬件模块很差。是否有中国董事会提供定制开发？我找不到任何低成本的Linux主板或安卓主板。如果我得到便宜的平板电脑，我可以将它用于我的实验吗？我的意思是我可以访问nand of und nor flash来刻录代码或设置bootloader吗？我需要一些非常低成本的板，我想发现内核组件。任何人都可以建议我做什么？

与几年前来自SoC制造商的昂贵（300-500美元）评估板相比，现在有几种“合理价格”的选择，即使不是非常便宜的，能够运行Linux的ARM板。
具有运行Linux的MMU的ARM SoC的成本最低的主板可能是Raspberry PI，零售价约为25美元（或“B”版本为35美元），应该可以在全球范围内使用。该板旨在成为软件开发的教育设备，因此其I / O功能是面向家庭或面向消费者的。 Beagle系列等其他主板更多地面向硬件黑客和工业用户，并具有更好的I / O扩展能力。
外壳中的单元不是裸板，而是带有遥控器，例如Mele A1000或带有SATA磁盘端口的A2000。它们作为可破解的媒体播放器销售，并且带有消费者就绪固件（Android）。

市场上的ARM板很少，价格合理。就像 BeagleBoard （印度的8-9k）是完全成熟的ARM主板，其精简版是 BeagleBone （印度约4k）。对于x86英特尔主板，有一个由pheonix组装，接近12k。
所有这些硬件都可以定制。你可以刷NAND芯片/ BIOS。把你的bootloader，内核，文件系统从头开始。

Odroid U2。凭借wifi功能，2GB内存将售价120至150美元。
答案 4 :(得分：0)
最便宜的开发目标当然是虚拟机（如果您希望使用与开发机器相同的架构）或模拟器（如QEMU）（如果您需要不同的架构）。
虽然模拟一个完整的图形系统，如高分辨率的Android平板电脑，并实际模拟处理器甚至可以加载现代机器，支持控制台模式或中等分辨率系统应具有可容忍的性能。如果架构是相同的，可以使用虚拟化，那么日常使用的性能应该很好（VM解决方案通常用于最终用途，而不仅仅用于开发测试......）
