我想用 shell 构建定制的 Linux 内核。我的硬件模块很差。有没有提供定制开发的中文板？我没有找到任何低成本的 Linux 板或 android 板。如果我得到一个便宜的平板电脑，我可以用它来做我的实验吗？我的意思是我可以访问 nand of nor flash 来刻录代码或设置引导加载程序吗？我需要一些成本非常低的板，我想在其中发现内核组件。谁能建议我该怎么做？

与几年前 SoC 制造商的昂贵（300-500 美元）评估板相比，现在有多种选择“合理的价格”，如果不是非常便宜的话，可以运行 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，其零售价约为 25 美元（或“B”版本为 35 美元），并且应该在全球范围内有售。该板旨在成为软件开发的教育设备，因此其 I/O 功能面向家庭或消费者。 Beagle 系列等其他板更多针对硬件黑客和工业用户，并具有更好的 I/O 扩展能力。
不是裸板，而是带有远程控制的机箱中的单元，例如Mele A1000 或带有 SATA 磁盘端口的 A2000。这些作为可破解的媒体播放器出售，并附带消费者就绪固件 (Android)。

市场上价格合理的ARM板很少。像 BeagleBoard（印度为 8-9k）是成熟的 ARM 板，而同样的精简版是 BeagleBone（印度约为 4k）。 x86 Intel板子，有一个由phoonix组装的，将近12k。
所有这些硬件都可以定制。您可以刷新 NAND 芯片/BIOS。从头开始放置您的引导加载程序、内核、文件系统。

还有cubieboard ATM 49 美元。
cubieboard的特点：

Odroid U2。具有 wifi 功能，2GB 内存的售价为 120-150 美元。
【讨论】：
最便宜的开发目标当然是虚拟机（如果您想保持与开发机器相同的架构）或模拟器，例如 QEMU（如果您想要不同的架构）。
虽然模拟高分辨率安卓平板电脑等完整图形系统并实际模拟处理器甚至可以加载现代机器，但支持控制台模式或中等分辨率系统应该具有可容忍的性能。如果架构相同，可以使用虚拟化，那么日常使用的性能应该没问题（VM 解决方案通常用于最终用途，而不仅仅是用于开发测试......）
