Hello everybody

I have a problem (again ....)

 

I implanted a bootloader that jumps to position 0xF000 in case of software update I should go back to the boot address 0000 but something goes wrong and it doesn't work.

 

Here is the question: using NVIC_SystemReset () I restart from the starting address 0000 (0x04000000) or do I stay in the F000 application area (0x0400F000) ???

 

Thank you all

 

Stefano
