I think I need a one click porting tool
If there were a one click tool, we would have clicked it already
The reality is that completing a port takes a lot of work, even for people who already have significant programming knowledge.
Successfully completing a port without any programming ability is extremely difficult, and the resulting port is likely to have major problems.
You can certainly teach yourself the things you need to know, but it's not going to be just a matter of finding the right tools or couple hours of reading tutorials. We can't just tell you what to do step by step because the process requires knowledge. I'm sorry if this is discouraging, but IMO it's better to have a clear idea of what you are getting into.
Witch tool I have to use to rebuild an existing CHDK port? CHDK compiler? I rebuilded one
Using which too? For windows,
https://chdk.setepontos.com/index.php?topic=12752.0 is probably the best one to start with.
but the tool did not make FI2 file..so I can't start the port
FI2 files require keys that need to be extracted from the ROM dump, see platform/fi2.inc.txt in the source. However, and FI2 is only required for the "firmware update" loading method. The bootable card method does not require one.
