Simulink Real-Time message "System Halted"

Hi everybody,

After a Simulink Real-Time boot (Matlab R2015b), the target machine window displays "System halted". Is seems it could be a problem with Ethernet card compatibility(?), but how can I find a 100 % compatible card? Could Mathworks give some reliable and clear information about Ethernet card compatibility?

Thanks. Gabriel

Hi Gabriel,

Regarding the 'system halted' issue, you can check if the 'ShowHardware' flag is enabled. The host cannot communicate with the target after boot when the 'ShowHardware' flag is turned on.

This is mentioned briefly on the following page:

ethernet card selection by ethernet index

It is important to turn off the 'ShowHardware' environment variable (which you may have enabled to see the Ethernet indices) to get a fully functional target boot.

To do so, execute the following command on the MATLAB Command Prompt:

setxpcenv('ShowHardware','off');

After doing this, rebuild the boot disk and network boot the target.

With regards to your question about ethernet card compatibility, here is some information:

The chipsets supported for model-based Ethernet communication are not necessarily the same as the chipsets supported for host-to-target Ethernet communication. In particular, fewer members of the Intel 8255X and Intel Gigabit chip families are supported for model-based Ethernet communication than are for host-to-target Ethernet communication.

The following is a list of the Intel Gigabit chipsets (along with device ID) supported for use with model-based Ethernet communication:

82541PI Intel® PRO/1000 GT Desktop Adapter 0x107C

82572Gl Intel® PRO/1000 PT Server Adapter 0x107D

82574L Intel® Gigabit CT Desktop Adapter 0x10D3

The following is a non-comprehensive list of the Intel Gigabit chipsets supported for use with model-based Ethernet communication:

82540EP/EM - (0x100E, 0x1015, 0x1016, 0x1017)

82544GC/EI - (0x1008, 0x1009, 0x100C, 0x100D)

82545GM/EM - (0x100F, 0x1011, 0x1026, 0x1027, 0x1028)

82546GB/EB - (0x1010, 0x1012, 0x1079, 0x107A, 0x107B, 0x108A, 0x1099)

82547xx - (0x1019, 0x1075)

82541xx - (0x1013, 0x1018, 0x101A, 0x1076, 0x1077, 0x1078, 0x107C)

82546GB/EB - (0x101D)

82540EP/EM - (0x101E)

82572Gl - (0x107D)

82573E/82573V/82573L - (0x108B, 0x109A)

82574L - (0x10D3)

631xESB/632xESB

82571EB/82572EI

82563EB/82564EB

Hope this was helpful.

Thanks,

Ankitha

Thanks a lot. But what do you mean exactly with "model-based Ethernet communication" vs "host-to-target Ethernet communication"?

Thanks. Gabriel
