Writing bytes to internal flash memory blocks all interrupts on the STM32L0 despite moving the vector table and ISR functions to RAM

The Context I have a embedded system running on an STM32L053 processor that needs to process STM32 hardware timer interrupts regularly and cannot be disabled. These top-priority interrupts cannot be prevented because it could cause a failure in the…
