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.
Is there a list somewhere of jailbreak-able kindles? I've been thinking of getting one to toy with for a while, but I don't want to accidentally get one that is more heavily locked down, or that we cant run our own code on for some reason
I am working on a self-hosted library server for jailbroken kindle and opted for using pure Rust for the KUAL app to sync books and annotations with the server.
It's just running `cargo build --release --target armv7-unknown-linux-musleabihf` with a .cargo/config.toml:
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
Depending on your firmware version, most jailbreak guides will have you either create an empty directory with the same name as the OTA firmware file (causing any OTA downloads to fail) or install an extension called `renameotabin` which renames the binaries responsible for performing the update, rendering them inaccessible.
This is a great point. Back when I was checking I think I was underwhelmed by the customization ecosystem for kobos but now I’m not sure what was stopping me/made me reconsider.
Upon further inspection there is also the Pine Note!
Tangential reply, but Druid has been abandoned. The spirit lives on as Xilem, but that doesn't have much traction either. It's very... exploratory in nature.
I'm partial to iced, which to me is the best GUI library in Rust by far. The Discord is super active if you have questions.

Here is the list detailing exactly the software versions supported and device support. This website will have everything you need.

It's just running `cargo build --release --target armv7-unknown-linux-musleabihf` with a .cargo/config.toml:
``` [target.armv7-unknown-linux-musleabihf] linker = "rust-lld" rustflags = ["-C", "link-self-contained=yes"]. ```
the downside is I can't use any c-deps. :)
I wrote about my experience in cross compiling zig on an old kindle some time ago.

It’s quite pricey but certainly more straightforward in its offering.
Kobo is the cheaper and has a color option and is likely slightly less hackable.
[EDIT] Ah, I think this is what I found:

Kobo’s switch to secure boot made things harder for Quill which seemed to be the only custom OS.
