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?
Example code to recreate the bug
N/A
SDK version
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)
N/A
Log/console output (if needed)
N/A
Sniffer trace (if needed) as an attachment.
N/A
Solved! Go to Solution.

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.

Yes I referred to the same and was able to port to an extent,
I was able to use SPI without DMA successfully , I read and wrote data to some files...
But when I use DMA for block read ,some byte errors are o, have you faced such issues ?
