Hello all,I converted the AVR230 DES bootloader application to be used with GCC and want to load it into my target, an ATMega32. I need to know (of course) what location I should feed into the linker script to place the bootloader.
In the datasheet , the application flash is said to end at 0x37ff and the reset vector is said to start at 0x3800 with BOOTZ set to 0 0 .
I do not understand this, as the ATMega32 has 32K of flash and address 0x37ff is exactly at 16K, ie halfway the application flash of the ATMega32.
I would expect the bootloader section to start at something like 0x7800 . Could someone please shed some light on this ? Thanks, Ewout Boks
