DRAM not available on cRIO9040

[Gryffin]

Hello all,

I am confused by something regarding the cRIO9040 and LabView FPGA.

On the datasheet for the cRIO9040, NI claims that it has 2GB of DRAM.

However, according to this article, the cRIO9040 seemingly doesn't have any DRAM available to be utilized for memory items. Can someone please explain?

Hi Gryffin,

the DRAM has to be accessable by the FPGA - which it doesn't seem to by with your cRIO9040.

The DRAM mentioned in the datasheet is available to the RT/Linux CPU, as is the SSD.

The FPGA can access nearly 5Mbits of block RAM…

Would you happen to know which cRIOs with FPGAs have access to DRAM (if any)?

Hi Gryffin,

why don't you call your local NI sales team?

I guess those FlexRIO targets support "FPGA with DRAM"…
