Hello,
I'm trying the snip.sd_filesystem application in Wiced Studio with the CYW43907 eval board and a 2GB SD Card.
In the sd_filesystem.mk makefile I have enabled FileX and exFAT support, as follows:
# for SD/MMC card support
WICED_SDMMC_SUPPORT := yes
USING_FILEX := yes
# default stack size was WICED_DEFAULT_APPLICATION_STACK_SIZE, 6K
# needs big stack size for deep directory processing
GLOBAL_DEFINES += APPLICATION_STACK_SIZE=1024*256
# enable FileX exFAT
GLOBAL_DEFINES += FX_ENABLE_EXFAT
$(NAME)_COMPONENTS := filesystems/FileX
However, the system always fails to mount the filesystem, regardless if the scared is formatted as exFAT or FAT16/32.
If I comment out the FX_ENABLE_EXFAT constant and format the sdcard as FAT16/32, the snip application works as expected.
So, the exFAT support seems not to be working. Is there anything else to do to enable the exFAT support with FileX?
I know that FAT32 is more than enough for a 2GB sdcard, but I'd like to understand if the system can really work with exFAT or not.
Thank you for the assistance.
Solved! Go to Solution.

Hello,
You need to disable GLOBAL_DEFINES+= FX_ENABLE_EXFAT for mounting to happen. It can not work with exFAT.

Isn't the FileX library supposed to work with exFAT?
Is this a limitation of the Wiced Studio porting of FileX or what?

FileX is comaptible with ExFAT. This is a limitation of WICED.
