Hello, I use stm32f415 and have bus fault with random adress. For example the content of BFAR register is 0x268dfb8; 0х4B404288; today i have 0xE000ED38. And frequency of bus fault change when I change the priority of DMA. With low DMA priority I have bus fault after 1-2 hours of programm work, with very high dma priority I have bus fault after 1-2 minutes. Please help me, what i must to do.
