Hello Seogjin,

We don't have FATFS for SPI SD on our HDK.

QJ

The FatFs source code & documentation are here: http://elm-chan.org/fsw/ff/00index_e.html

It's really not hard to port...

Thanks. We have a plan to develop FAT FS for USB stick, but not for SD card at this moment.

Hi QJ,

QJ>Thanks. We have a plan to develop FAT FS for USB stick, but not for SD card at this moment.

Any progress in this direction?

Hi Dmitri,

I am working on USB bootlaoder. The FAT FS will be part of the project, but it will be a simple version. I hope to release the beta version in April.

Hi QJ,

Thanks. Do you have USB part outlined already? Or you concentrated on the boot loader itself?   I need a USB stick writer. 

Regards, Dmitri.

Hi Seongjin,

It is not a response for this particular forum but if you trying to work with FreeRtos and SD card you can try FreeRtos+IO example. It does exactly SD card + FatFS as you asking (not for RM48).  You will need to figure out how to replace SPI part but it is doable. Not a rocket science.

Regards, Dmitri. 

Hi Dmitri,

USB bootloader (from memory stick) is a big project. This project consists of 3 main parts: USB HC driver, MS (USB Flash Mass Storage) class (bulk read, buld write, etc), FAT FS (FAT16 only). I am still working on the project and it won't be ready until April. I am sorry.

QJ

Thanks, looks like I need to figure out it myself :-).

Regards, Dmitri.

Hello Seongjin，

We don't have FAT FS for SD so far. I will have FAT16 FS for USB memory stick in April.

I am also having the same issue: RM48 with SD card and USB stick support.

I am looking at a solution of adding a cheap Microchip PIC24 or NXP with USB host and SPI support with File system on SD card, talk to this from the RM48 via SPI. Have used Microchip code on PIC24 and PIC32 for both file system and USB stick support very successfully and it is absolutely straightforward.

Hello,

Is the driver for the FAT16 FS drive ready?

I would like to reuse the USB Host Controller driver in my application. I am trying to interface a USB Webcam to the board.

Hi QJ,

I am working with the RM48 and could really benefit from an example of how to implement a USB Bootloader.  Do you have an update on the USB Bootloader project?  Thank you.
