References
Useful links
General-purpose references worth keeping close. Anything specific to one topic belongs on that topic's own page instead — this list is for material that spans domains or is just generally handy.
Specs and standards
- Linux kernel documentation —
Documentation/in the kernel source tree, especially the device tree bindings underDocumentation/devicetree/bindings/. - Device Tree Specification — the formal reference for device tree syntax and semantics, useful whenever Linux drivers and device tree overlays don't line up.
Tools
i2c-tools—i2cdetect,i2cget,i2csetfor I2C bring-up.libgpiod— modern userspace GPIO access, replacing sysfs GPIO.minicom/picocom— serial terminal clients for UART console access.tcpdump/ Wireshark — packet capture, invaluable when debugging anything under Networking.
To do
Add books and datasheets as their own topic folders under References once there's enough material to organize (see GUIDE.md) rather than growing this single page indefinitely.
