I'm using STM32F030K6T6TR and i'm trying to use the flash memory. It worked to erase the pages that i need but when i write i get a hard fault error

if (HAL_FLASHEx_Erase(&EraseInitStruct, &PageError) != HAL_OK)
{
/*

User can add here some code to deal with this error.
PageError will contain the faulty page and then to know the code error on this page,
user can call function 'HAL_FLASH_GetError()'
*/

Can some one please tell me why i get the error at HAL_FLASH_Program()
