Bare-metal programming for ARM - A hands-on guide
The subject of this ebook is bare-metal programming in C for an ARM system. Specifically, the ARMv7-A architecture is used, which is the last purely 32-bit ARM architecture, unlike the newer ARMv8/AArch64. The -A suix in ARMv7-A indicates the A profile, which is intended for more resource-intensive applications. The corresponding microcontroller architecture is ARMv7-M.
Summary
This hands-on ebook teaches C-based bare-metal programming targeting the ARMv7-A profile, emphasizing low-level firmware techniques for application-class ARM cores. Readers will learn how to write startup code, handle exceptions and interrupts, and interface directly with hardware without an operating system.
Key Takeaways
- Understand the ARMv7-A architecture and how it contrasts with the ARMv7-M profile used in microcontrollers.
- Implement low-level startup code, vector tables, and exception/interrupt handlers in C and assembly.
- Write bare-metal firmware that interfaces with peripherals via memory-mapped registers (GPIO, UART, timers).
- Apply debugging and development techniques for running and testing code on real ARM hardware.
Who Should Read This
Embedded software engineers or firmware developers with C experience who want to learn practical bare-metal programming on ARM application-class cores and improve low-level hardware interfacing skills.
