Im aware of the order dependency of the linker script, and I have tried to put .rawdata after .text in flash and still it does have different values from the values that should be in the .rawdata only at runtime

The problem was that I was not enabling GPIOA clock, but GPIOB clock becauseRCC->AHB1ENR |= (1 << RCC_AHB1ENR_GPIOAEN) was shifting by 1;so instead i have just put RCC->AHB1ENR |= (1 << RCC_AHB1ENR_GPIOAEN_Pos)
