PIL mode with STM32 Embedded Target, IAR, and J-LINK

Hi

I've recently been playing the with STM32 Discovery using IAR and J-LINK and Simulink.  I've managed to set everything up okay, and can deploy some of the test Simulink models that ship with the STM32 Embedded Target software (e.g. blinking LED).  This all works fine.When I try to run the IIR filter PIL model, however, I run into a problem.  After setting the ''reference'' model up with my toolchain and selecting PIL mode, I attempt to run the top level model.  It get's through code generation okay, but errors out when running the generated makefile for the model reference PIL block. I've attached the output (modified to shorten paths) below:

Hi Pascal.

Thank you!  That has solved the compilation of the PIL code generation problem.Another question (sorry but I'm a complete newbie to this).  I've connected the J-Link to the Discovery board as per the instructions on this application note: 

http://www.segger.com/admin/uploads/evalBoardDocs/AN00014_ConnectingJLinkToSTM32F407Discovery.pdf

Do you know if the J-LINK have a serial connection capability or will I have I to connect to the USART pins on the discovery board using a separate serial device?Thanks againDaryl.

Hi Pascal

As a follow on to my previous question, if I do need to use a separate serial device, do you have any specific recommendations or requirements for the Discovery board?Daryl.

Hi Daryl,

there is not DB9 connector on Discovery board (no level shifter). You can not directly connect a serial com cable. But, you can use a USB convertor like this one (for example):

http://www.amazon.fr/PL2303HX-Convertisseur-vers-c%C3%A2ble-module/dp/B00ATALGI6

Then, you can connect Rx/Tx to discovery Pin. There is a popup windows during build to select Discovery port. PC COM port used must be enter as a preference  using cmd: getpref('STM32F4xx','COMPort') to know selected COM port. setpref('STM32F4xx','COMPort','COM5') to set COM port used (here COM5 for example). Best regards Pascal

Sorry for the late response, but I have been away.  Thanks for all your support and advice.  It has been very helpful.

Daryl.
