Hi

I'm new in STM32 software development and I have 2 questions:
1) Nested interrupts: I've tried several settings of the preemption and the sublevel interrupt but nothing help's. I need to have Timer1 interrupt the highest priority Interrupt, so it can interrupt an USART1 interrupt. Is this possible? If so, how?
2) I need to have some const variables at an absolut address in flash memory. It should be at the end of the flash memory. How can I do that?
I'm using the GNU compiler from raisonance and RIDE7.

Best regards Edi
