Bare-Metal C for Modern ARM
Bring-up, linker scripts, and the boot you cannot debug
Cortex-M and Cortex-A boards arrive with reference manuals and almost no working examples. This book fills the gap: writing the linker script that actually places .data, debugging the boot vector with SWD, building your own minimal CRT, configuring the MPU, and shipping firmware with a recovery path. Every section ships with verified code for STM32H7, Nordic nRF53, and i.MX RT.
Lior has brought up custom silicon for medical devices, satellites, and the kind of low-volume industrial gear that never appears on a Hacker News front page. He writes for engineers who own an oscilloscope.

The bring-up bible
We onboarded three new firmware engineers this quarter using this book. The linker script chapter alone saved us a week of meetings.
