Cannot boot Simulink Real-Time kernel from custom target computer

I am unable to load an SLRT kernel onto a DIY target machine. I attempted to load the SLRT kernel to the PC using both flash drive and network boot methods, but the system still boots to the native OS, which is Debian. I tried adjusting the BIOS boot settings but it still loads to Debian. I was able to establish IP communication via Ethernet between a laptop and the target machine.

There are multiple reasons why this may happen:

• It is possible that the custom computer does not have a FAT32 formatted drive. Although this does not prevent from loading the kernel, you would not be able to use the computer after the kernel is loaded.
• The Ethernet card may not be Preboot eXecution Environment (PXE) compatible. Please keep in mind that PXE capability is required for using network boot method, and not all network cards are PXE capable.
• It may be related to BIOS security. Loading another kernel at the BIOS level might have been prevented for security reasons.
• Please note that custom targets are no longer supported with Simulink Real-Time R2018a and newer. Use releases R2017b or prior.
