痛点为 AI 基于上游原始证据的初步提炼；未包含额外中国市场检索。
用户想要在 Kindle 上运行自定义软件（如时钟、Home Assistant 仪表盘），但 Kindle 的封闭系统和低性能 ARM 处理器导致无法直接编译或运行 Rust 程序。现有流程需要先越狱设备，再通过交叉编译工具链（如 Cross）为 ARMv7 musl libc 目标构建二进制，过程复杂且容易出错。用户提到“从痛苦的经验中知道在低功耗设备上编译 Rust 是不可行的”，说明手动交叉编译耗时且不稳定，导致开发周期长、调试困难。这种摩擦使得原本简单的想法（如用 Kindle 做时钟）需要大量额外工作，阻碍了用户快速实现个性化功能。
I recently jailbroke my 7th generation Kindle Paperwhite. While my motivation probably should have been "breaking free from Amazon's clammy and tightening grip", the truth is I wanted a way to use it as a clock on my nightstand. I found this project and figured I could just make some adjustments to the code. And that worked fine . But as I now had opened the door, I started thinking about if I could get Rust to work on the Kindle as well. Maybe I could do more useful stuff with it? As I have recently started to tinker with Home Assistant and smart devices again, the idea of a dashboard for some of the features could be a fun project. And while there are probably many perfectly fine projects out there, I haven't made any of those. Telling a programmer there's already a library to do X is like telling a songwriter there's already a song about love. -Pete Cordell After some research I found out that I needed to target ARMv7 and musl libc. I have dabbled with Rust on ARM machines before, and know from painful experience that getting the Rust compilation toolchain to work on such low-powered devices is a non-starter. Luckily there are great tools for cross compilation. My go-to for cr
This is cool, thanks for sharing. I recently compiled Rust / Slint on a LicheeRV Nano, which is RISC-V 64bit musl[1]. It's a little portable audio player I'm working on, the compile process is done via custom Cross docker image. Currently I'm evaluating Battery Pal[2], because the TP4057 Module was not stable enough to power USB-C to 3.5mm Adapters reliably. So far it seems to work as expected. 1: https://github.com/nanowave-player/nanowave-ui 2: https://pnlabs.ca/batterypal/
This is awesome! How reliable are kindle jailbreaks/avoiding updates, etc? Have opted for other devices like the xteink (or a boox in the future) due to what seemed like a relatively small ecosystem around “aftermarket” kindle modifications. The kindle would be a great option if it could be reliably jailbroken and loaded with custom software
This looks cool, and one of the first posts I've seen on HN in a few months where I genuinely wanted to try it.

Good work! I guess you need to leave it plugged in?
