How GCC optimization (-O0/-O2/-Os) rewrites your code, why forgetting volatile causes a hang, and how to read Thumb-2 instructions with objdump. https://electwork.net/en/posts/stm32-episode11/ Sat, 02 May 2026 00:00:00 +0900 https://electwork.net/en/posts/stm32-episode11/ Understand STM32 linker scripts (.ld) and map files by learning what .text/.data/.bss really are. Covers LMA vs VMA, the startup sequence that copies .data and zeroes .bss, and reading arm-none-eabi-size. https://electwork.net/en/posts/stm32-episode10/ Thu, 30 Apr 2026 00:00:00 +0900 https://electwork.net/en/posts/stm32-episode10/ Stop letting UART transmissions stall your main loop — DMA fixes it. From STM32's bus architecture to transfer-complete callbacks, buffer management, and the D-Cache coherency trap. Episode 10 of the series.
