Summary Issue or question:

    We want to add an 128GB SD storage card to WICED, and then we can using WIFI storing and reading file into the SD card via WICED. We plan to use a SDIO to USB adapter chip connect the SD card and the MCU USB port. I think this need implement FAT32 file system on WICED OS. So any suggestion to implement FAT32 file system?

N/A

WICED SDK3.0.1

HW Platform (if it is a peripheral or MCU issue)

BCM943341WCD1

Development environment usually agnostic, but needed if you have a installer or toolchain issue)

A quick search on the Internet shows there are a number of open source FAT32 file system implementations.

I would recommend porting a suitable version as a library so it can be easily reused in other applications.

But after some time the platform gets restarted... Any idea what might be goin on?
