Hi everyone, Two questions please: 1. I understand the idea of a bootloader, can someone with experience in that area please supply me some info on implementing a bootloader section for f873/f877 or point me in good direction. 2. Anybody who has an ICE system please answer some basic undocumented questions, such as emulation speed, max current sink on pins and some other behaviour patterns. I would much appreciate any help.
