external mode with custom RTW target

[Frederic]

I have a problem to use "external mode" with a custom TLC
file that derives from grt.tlc (file is attached at the end
of this email).

When I set Interface to "External Mode" in RTW configuration
parameters, the "Transport Layer" control only contains the
"none" option.
When using the grt.tlc target it contains the expected
options "serial, tctpip...".

What do I need to change in my TLC file to have access to
those Transport layers?

I found-out that I can edit the mdl file and force the
"ExtModeMexFile" parameters to "ext_comm" instead of
"noextcomm" and it works! I can connect to my target from
Simulink.

But of course ExtModeMexFile is overwritten next time I save
the model. I need to be able to set the transport layer from
Simulink Configuration's dialog.

Thanks for any help

I'm replying to myself, I found the solution after digging
through the m source files in the toolbox/simulink directory.

To add tcpip external mode support to a custom target,
create a sl_customization.m file with the following content:

function sl_customization(cm)
disp('Adding tcpip external mode to test target');
cm.ExtModeTransports.add('test.tlc', 'tcpip',
'ext_comm', 'Level1');
end

Mentioning this in the doc would be nice (in case somebody
at The Mathworks is reading this).

Hi Frederic,

I am also facing the same problem, as you faced initially.
But i am not able to resolve it.

Even i created a a function
-----------------------------------------------

function sl_customization(cm)
disp('Adding tcpip external mode to QNX target');
cm.ExtModeTransports.add('qnx.tlc', 'tcpip', 'ext_comm', 'Level1');
end

-----------------------------------------------------------

I have this function in the same folder, where the qnx.tlc file is ...

Kindly help me...
my email id is sriha...@vrindatech.com

Thanks

Hi Frederic..

I get the following error, wen i run the function..

-----------------------------------------------------------

sl_customization

Adding tcpip external mode to QNX target

Undefined variable cm.

Error in sl_customization (line 4)
