An afternoon spent finding where a Nerves target's Erlang version is really decided — and discovering it is encoded in the filename of a patch inside a dependency I had never opened. Plus the Kconfig default that will silently move you to OTP 29 the moment you bump.
Four packaging bugs between a Nerves system that builds and a firmware that flashes — plus the kconfig hang that looks exactly like a working build.
Why I wrote a custom Nerves base image file by file for a CompuLab IOT-DIN-IMX8PLUS instead of forking a sibling board's system.
Wiring signing into the build, and a correction worth more than the wiring: I planned to point fwup.conf at signed artifacts, and that was the wrong layer entirely — the signed bootloader is not in the .fw file at all.
Three real bugs blocked the first three attempts: a nerves package version whose error message points nowhere near the cause, a missing .tool-versions, and the same SPL SRAM overflow track A hit. Plus the arm64 header field that is at offset 0x10, not 0x4.
