Unable to format or mount Exfat on any version of sdk

[davidawesome02]

Update for anyone looking at my previous two issues, which are still issues, You can use 6a4d89bfeb6d8237da3e63ac66a6207c8af1c7bf to run them still (if you wana clone read https://stackoverflow.com/questions/3489173/how-to-clone-git-repository-with-specific-revision-changeset)

Ok, so because 6a4d89bfeb6d8237da3e63ac66a6207c8af1c7bf is the latest really working one, I need help, I am not sure if I can ask here as it is not a real issue as right now only a outdated version works, so technically it coulda been fixed....

I cannot use exfat because of error 19: LEAVE_MKFS(FR_INVALID_PARAMETER); /* no-FAT? */ on https://github.com/bouffalolab/bouffalo_sdk/blob/96533598ec949647be9a74d22ed5851604265957/components/fs/fatfs/ff.c#L6727

---- above has comments explaining each option but I removed them with a regex :)

and only modified main.c to use the commented out FM_EXFAT

I cant format to exfat or mount to exfat as it just returns errors, thanks for anyone who can help, and just so you know im more active on the pine discord.

This is a problem with a partitioning and mounting and I cant see why right now, please help!

Thanks, and please fix your repo

UPDATE: I FIXED IT, this was a complex one, and this sucks; ok, so you have to modify the exfat in the main file in the components also, use the old version for support (or fix the broken parts (I think it might be loading the unicode option makes it too big and is now set by default after v2.0 but not testing rn)) then use in main the correct fs type, and add it to be 512*256 for it to work (above 128 and I didnt know what to put so deal with it)

THANK bro, and please fix this or add comments about what dose what, and add the if statement in the main config for EXFAT support not just everything relating to it.....

I will add a merge request if I figure out github eventualy :)

[davidawesome02]

nvm I was too quick, it formated and can write and read but gparted still has seek errors now :))))))

[davidawesome02]

ok, did more testing and diffed the files betwine versions, NOTHING SEAMED TO CHANGE, did yall even test this, because this partition table is invalid!

thanks, gonna now read the spec on how exfat works and gpt partition tables see ya later

[davidawesome02]
