## Summary The STM32F412 has 256 KiB of system SRAM at `0x20000000` and no CCM. The F2/F4 heap map never named it, so `SRAM1_END` fell through to the 128 KiB default at `0x20020000` and the upper half was left out of the heap. ## Impact - New feature: NO - Impact on user: YES, F412 boards get the upper 128 KiB of SRAM in the heap. - Impact on build: NO - Impact on hardware: NO - Impact on documentation: NO - Impact on security: NO - Impact on compatibility: NO ## Testing `nxstyle` clean on `arch/arm/src/common/stm32/stm32_allocateheap_m3m4_v1.c`. PX4 carry is PX4/NuttX (10.3) and a matching 12.12 backport; those rebuild `ark_can-flow-mr_canbootloader` / `ark_cannode_canbootloader` with `CONFIG_ARCH_CHIP_STM32F412VG` / `CG`. -- This is an automated message from the Apache Git Service.
