STM CircleOS forum / FAT system and SD Card, ARM STM32F103RBT

Vinicius · 2009-01-23 18:18:17

Hello,
I`m using ARM STM32F103RBT6. I`m able to record and read data in SD Card with a raw format(Using simple SPI).
But I have to use the FAT system because after recorded the card will be read on a PC.
Anyone have any library, documentation or example using FAT to help me?
*I already tried the DOS and EFLS exemples from ST forum and both didn`t work, go to a HardFault Exepition interrupt.

Thanks,
Vinícius

Hi,

with several sources for AVR and STM32 I've got a solution for reading and writing FAT32 compatible file system with STM32 modified PRIMER I.

The FAT-File-System is able in A3670.zip written for AVR-controller. The sources are usable under GNU public licence and some changes are nesesaray.

The below address is not longer working but the zip file is available.

read.pudn.com/downloads40/sourcecode/windows/vxd/139966/A3670/firmware V1.00/main.c__.htm
- this link is not zip but the source code from the main.c that demonstrates the capability of the FAT-system.

The SPI-drivers (STM32) for MMC/SD-Card was written by Frank Goetze - www.embedded-os.de and the rights for using the sources must be cleared by them.

USART1 was used to communicate with PRIMER via hterm or similar terminalprograms using a XPORT and com port redirection.

A subset of current commands are possible eg. md, cd, del, copy, creating files and write to it, hd_info, cluster dumps etc.. The tested SD-card has a capacity about 1 GB, only working on normal SD-format not on SD-HC.

You can also use DosFS (which is currently part of CircleOs) and use the MMCSD over SPI implementation from the ST STM32 example library.
