Hi,
I am using Simulink Real Time for doing a rather lengthy test where I want to log several GBs of data before loading it from target to host.
I found the signal logging data buffer size in doubles and tried to increase it to a value that concurs with 5 GB. The target has 8 GB of RAM available. Whenever I try to build and deploy the model on the target I get a fault saying that the model memory exceeds available memory (I will post the exact error when I get back to work). It seems I can select a maximum of around 450 MB before I get into this problem.
The target is booted from a usb disk with the RAM option set to 8 GB. I also tried auto, but with no improvement.
Has anyone had this problem? or am I missing something?
Best Regards, Jesper

Hi Jesper,
Your application sounds like a perfect example where someone would use a Real-Time File Scope, unless I am misunderstanding your requirements or objectives.
This block will let you store data up to 4 GB on the target computer. Please refer to our documentation for some examples on how to use this block.
Cheers,
Sebastian
