Access to eMMC Disk on an sbRIO 9609

[Pascal981]

Hello, I am working with an sbRIO 9609 and on my FPGA project I ve added a FIFO and a memory. A s I understood these are internal memory to the FPGA so I was wondering haw to acces the eMMC Disk (4 GB ) of the sbRIO and use it.

Thanks.

Hi Pascal,

transfer the FPGA data to the RT host, then you can use typical file functions to access the sbRIO "harddrive"…

Thanks Gerdw for your response, I am using open/create file in the RT host but when entring a file path it opens the Host computer memory not the sbRIO hard drive.

Haw can I do it ?

Thanks

How can the RT target get access to your host computers harddrive? That's not possible!

On cRIO an external drive usually is mapped as drive "u".

Did you read the manual of yur sbRIO to learn how the eMMC is mapped? Did you check with MAX which drives/patch are available in the RT target?

I am using a DMA to transfer data from the FPGA to the HOST. Here attached the project explorer and the VI in the sbRIO.

Thank you for your help.
