In all application note that i read about teh bootloader I only see a slave processed bootloader. So I meen I putt in the toploader the bootload picture and I need a 2. with bootloadabel(master). My problem is now that I woud need an aktiv bootloader. I will get data from Uart this data i have to check for a updatetyp. If this is correct, i make an update(customer). But in my case the update ist encoded so i have to decode first and after that i can write them in the flash. Ther for I would need an part of Flash that ist save against update and everytime on the same adress(so we make it just ride now). But i dont find anything about that. A exampel would be nice.
