Hello,
is it possible to store image data in the sdcard through streamin mode from the fpga?
my hardware design is..
gpif 2 (slavefifo) (ptos & stou) usb2/3
image sensor<->fpga<-------------------------> fx3 sdcard port <---------------> pc in slavefifo mode and without any filesystems in the firmware i.e. only raw data streaming.
ptos ->p port data to s port (sdcard write operation).
stou ->s port data to u port(sdcard read operation).
regards,
geetha.

Hi Geetha,
Yes it is possible to store data from GPIF side to SD card using a file system in the firmware side. Please look into "fatfs" firmware that comes along with FX3 SDK. Then to read the data from the host there is no need to implement file system on the firmware side. Your device should come up as a mass storage device and then window driver will take care of the file operations on the SD card.
Thanks & Regards

Hi,
To retrieve data from the SD card you have to install File system on it.
Otherwise please tell me how you are planning to read the SD card.
Thanks & Regards

Hi Geetha,
If you want to save only raw data in the SD card then there is no need to install file system in the firmware.
