Why can't Simulink real time find the FAT32 partition on my computer ?

Hello,

I am currently working on Matlab R2016b and Simulink Real-time 6.5. My target computer is a Dell Optiplex 780 with 3GB of RAM. I boot the target kernel with a CD, configured with no graphical mode and no secondary IDE.

I have just erased the Windows OS from my target computer to install Ubuntu. During the installation process, I have created a big FAT32 partition intented for Simulink Real-time. However, when I boot in the target kernel, I still have the message "Error: No accessible disk found: file system disabled". I could not find on the forum an answer for my problem. I read this post, but I cannot apply the solution since I don't have a Windows OS on the computer anymore (and the solution did not work for the author anymway). Could somebody help me understand why my FAT partition is not detected and find a solution?

Thank you,

Guillaume

These error messages can occur for multiple reasons. If your target PC has multiple partitions, you'll need a boot manager to choose which partition you want to boot from. Make sure that you have set up your BIOS as the documentation mentions: https://www.mathworks.com/help/xpc/gs/bios-settings.html

Also, try selecting the 'Enable secondary IDE' option in the xPC Target Explorer and reboot the machine or recreate the boot disk. When this option is checked, the xPC Kernel will sometimes find a drive installed in a computer that was not previously detected.
