On-device exFAT formatting does not work

limi commented 3 months ago

Knulli build version

knulli-h700-rg35xx-plus-40-20240530

Your architecture

RG35XX H

Issue description

Formatting the default partition for games to exFAT does not work. This is especially problematic since you default to ext4, which isn’t readable on Windows nor on macOS by default.

Detailed reproduction steps

Write the latest version to an SD card
Boot it up, let it do its thing
Try formatting the drive to exFAT
Insert the card into a macOS device

Result: the drive does not show up at all.

Here’s the disk geometry according to Disk Utility:

FWIW, I tried reformatting the separate partition to exFAT on the macOS side, and that just broke the SD card setup entirely. No idea if the disk geometry or partition map is incompatible or something like that.

It doesn't work for me either. Do it from Windows: Click on Manage Devices and format it from there

still does not work. Windows does not recognize the formatted partition as exfat filesystem

I have the same problem This is particularly critical since:

On-device format does not work
Wifi does not work with WPA3, so network sharing also is no option
Mac format with exfat somehow corrupts the SD card

same here - it worked the first time (i formatted my sd because of rom folders being messed up) - then now nothing - i try to format sd2 in exfat with device + reboot and now my computer won't even open the drive

Can confirm, exact same behaviour. Fresh Anbernic RG40XXH out of the box, fresh flash of Knulli (latest version as of today, just downloaded), no matter what I do, the formatting doesn't work. Have tried restarting, have tried a re-flash, have tried multiple things.... but just no cigar.

My Macbook is still reporting the disk as ext4 with diskutil as well.

I found a way around it: Format the card in exfat from the device. Then hit backup user data to the freshly formatted sd card.

Plug it in your macbook and you will see a bactocera folder. (I renamed the sd card "SHARE" ) Drag and drop the content to the root of the sd (make seure to show hidden files)

Plug the card back in and set the storage device to the sd card.

Restart the device and it will load all Your backup data. Make sure the storage device is set to the second sd card (share)

Sitch off, insert the card in computer and add your roms.

This has worked for me.

I have the same issue. I have fresh Knulli installed on RG40XX V and formatting doesn't work. I tried the steps above and doesn't help. Manual formatting on Mac just breaks structure of the card completely.

Not sure if the rg40xx has 2 sd slot - on my rg35xx h i left the main sd card1 alone after Knulli instal and did all of the above with sdcard number 2. if that helps...

It has 2nd slot but unfortunately, mine is broken and can't read any card. That's why I'm trying to figure out best single card setup other than stock OS. I'm close with Knulli but this formatting thing doesn't work and I can't add any games as I have only Mac :/
