Strange Behavior with SRAM and RAM Addresses on STM32L431? Hello everyone,I'm working on an STM32L431-based custom board, and I’ve encountered some very strange behavior that I can’t seem to explain. I have two variables pointing to different memory regions (SRAM and RAM), but when I modify one variable, both variables change as if they are somehow linked. To recreate the problem that I am having, I wrote a simplified version of the code below.Here's a simplified version of my code: volatile uint32_t *ram_var = (uint32_t *) 0x2000C004; // Points to RAM region
volatile uint32_t *sram_var = (uint32_t *) 0x10000004; // Points to SRAM region
int main() {
*sram_var = 10; // Expected: ram_var = 0, sram_var = 10, but both are 10!
*ram_var = 15; // Expected: ram_var = 15, sram_var = 10, but both are 15!
(*sram_var) += 5; // Expected: ram_var = 15, sram_var = 15, but both are 20!
(*ram_var) += 5; // Expected: ram_var = 20, sram_var = 15, but both are 25!
(*sram_var) += 5; // Expected: ram_var = 20, sram_var = 20, but both are 30!
