Broken by 635cfa. On an stm32 the heap is formed from const uintptr_t g_idle_topstack = HEAP_BASE; where HEAP_BASE is &_bss + CONFIG_IDLE_STACKSIZE. Both these values are not deterministic. One comes from the compiler, the other the system configurator. a 3 byte bss and 250 byte stack would lead to and unaligned address used as the heap to be. The compiler used clever `strd r1,r3,[r5,#8]` to store 2 values in one memory cycle into the heap_impl struct. Resulting in a hardfault. Change the amount of bss or the CONFIG_IDLE_STACKSIZE could lead to a non-functional NuttX system. |
