Rockbox on a iBasso DX90. Can Rockbox work with SDXC larger then 128GB??

[LennoxConner]

Hi , i got a question regarding Rockbox on a iBasso DX90.
Im in a bit of a hurry, a guy put an advert online to sell his iBasso DX90 (spoke to him on the phone today)

I told him i needed to figure out some things regarding Rockbox and reading SDXC cards larger than 128GB.
My old Cowon d2 and omegle xender Rockbox will go as high as 128GB.(as it looks for now) FAT32 formatted.

The DX90 can accept micro sdxc up to 2TB. On DX90, will Rockbox work with cards larger then 128GB exFAT? or FAT32?
unlike with the cowon, on the DX90 all firmware is installed on the player if i'm right.

Thanks

Rockbox only works with FAT32 partitions.

The size limits come from the FAT32 filesystem itself, not Rockbox.
With typical 512 byte sectors, FAT32 can go up to 2 TiB per partition; with 4k sectors the limit is 16 TiB per partition.
