what tool to use to create a large fat32 partition?

I tried
http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm
to format a 256GB sd card to FAT32

After placing the CHDK build on that card I've had an error after boot stating missing modules.
I reformatted back to exFAT and placed the same CHDK build on it: boots CHDK without error.
started over, same result.

Does anybody have a clue what I did wrong or what tool might be better suited to create a large FAT32 partition?
...it's to see if stick can make a dual boot with that size, but now it does not recognise the card

Sounds more like you failed to copy CHDK correctly to the card rather than a card format problem?

When you say "placing the CHDK build on that card" does that mean you expanded the zipped download file fully onto the card - with all the associated folders and subfolders created and filled with the files that are supposed to be in those folders?

Also, what camera are you using?

yes, same set of files and folders works when the card is formatted exFAT, but not when it's formatted FAT32...
both times CHDK seems to work abeit the 'missing modules' notion when in FAT32
done it twice to see if i did something wrong.

Again, what camera?

Also, are you trying to do this with dual partitions?

I did this with a 128GB Card for a while:

cmd (start prompt)

diskpart (new command window)
list disk (displays volumes)
select disk 2 (select the number depending on the drive, of course!)
clean
create partition primary

Now go back to the standard "cmd" command window
d: (change to drive where H2Format.exe is located)
cd temp (if the h2format.exe is located there)
h2format.exe (enter)
h2format h: 64 (then wait about 1minute)

It's my S95, that supports dual boot.
just now I tried formatting FAT32 with
https://rufus.ie/
and h2format...
same result, missing files when i boot via the firmware update method on the FAT32 formatted 256GB card.
working when same card is formatted exFAT

for now it is a single partition FAT32 with firmware update method.

So do you have one partitions on the card or two?
