How to mount exfat on OpenWrt

I have installed the exfat package. After I use "mkfs.exfat /dev/mmcblk1p1" to format, I want to use "mount /dev/mmcblk1p1 test/ " but the following error appears

mount: mounting /dev/mmcblk1p1 on test/ failed: Invalid argument

please help me to mount sdcard, thanks!

is there a ./test directory ?

is /mnt/test and i'm on mnt now

and by exfat package I assume you mean kmod-fs-exfat ?

that's right

try using full path


mount /dev/mmcblk1p1 /mnt/test/
