Hi, I'm not suprised that there are overlapping sections. In a bootloader, what happens is that either in the firmware or the software the program's RESET vector must be moved to somewhere within the boot location. Otherwise, once u bootload the program the bootloader won't run anymore! --- Chen Xiao Fan wrote: > It seems to me that my problem can not be solved by > hexmate > and some other methods here.
