I added experimental exFAT support. It should allow updating CHDK on a partitioned exFAT card. Is somebody willing to test it?
my mistake, i downloaded chimp master, but couldn't find chimp.exe inthere.
downloaded 0.9.5 from
https://github.com/CHDKUtil/CHIMP/releases/ with the dated folder, but that does not seem to update the second partition only the first. 'installation aborted' when i try it on exFAT
what i did notice is that it created also part of the chdk folder and an extra folder starting with an _ on the FAT16 partition. mind you, on a card that is made dual partition in the cam there is not enough room for the complete chdk folder.
