TMDXLCDK138: SIMULINK_ CCS_CODE GENERATION

Sajad Rather4

Part Number: TMDXLCDK138

Hello Everyone (including TI & MATHWORKS)

I am working with the Simulink (MATLAB 2015) with CCSv5.5 for Code generation for OMAPL138LCDK. After reading a lot of documents & many forums ,i Sucessfully configured the MATLAB with Simulink for code generation.I wonder why TI or Mathworks have not documented the required steps needed to be performed.
Anyway I dragged an ADC block followed by a DAC block with default configurations(8khz Sampling rate and samples per frame 64) in simulink new model.All the parameter's are set ,After building the model .the .out file is generated.

After that i created a new target file in CCS and connected with my board,& loaded the simulink generated .out file.it gets loaded on the board ,resuming it gives no output from LINEOUT,when an audio source is connected to LINEIN port.

I rechecked the target configuration with a ccs version of .out generated,it was working fine.So from this i am sure that the problem is with the .out generated from Simulink. Then I connected a 2W portable Speaker at LINE OUT and audio Source at LINE IN.After building the File again the speaker output is very low ,almost negligible.I thought it might be due to ADC gain ,so after adding a gain block (12DB) in between the ADC & DAC ,it shows same response.

Tried lot of things like changing gain,sampling rate etc.but all in vain.

Also When i created an another model for C6713 DSK , ADC followed by DAC.The generated .out file from simulink for c6713 DSK is working Fine using MATLAB_SIMULINK_CCSV5.5.

Now from here i am sure that the problem is in connecting the blocks of C6748 in Simulink or maybe something else.

If anyone here have worked around it ,please a liitle help needed here.

Hi Rather,

So from this i am sure that the problem is with the .out generated from Simulink.

Please refer to Mathworks forums. E2E does NOT support simulink.

While there are a couple of us from MathWorks watching the E2E forums, you definitely should contact MathWorks Technical Support for prompt support for MathWorks software questions.

Cheers,

Hello Brain & Yordan Kovachev

Thank You...!

As I said, Simulink is NOT a product of TI, so we do not support it.

Hi Sajad,

Contact Tech Support (as per my link), not just post in the community.

Hello Brain,

Thank you for your kind Support.

It seems the Simulink blocks for c6748 are only supported for C6748/OMAP EVM boards only ,it doesn't support the LCDK boards(i am using).Mathworks also confirmed that they have not tested the same for LCDK kits.

To work with C6748 LCDK boards,User need to create his own S_function Blocks by using .c & .h files.

One Last thing,MATHWORKS & TI should Provide a well documentation for interfacing MATLAB with TI borads,Many people want to make work around it ,but as due to lack of resources and support they have to find the alternative(using Complex & Time consuming coding).

Regards

Rather

Hi Sajad,

MathWorks discontinued our custom support for C6000 in R2016b.

We have many customers who use Embedded Coder to generate code and import it into CCS and run it on a whole plethora of TI devices, including C6000. In some cases, you do need to create your own glue code or S-Function blocks - this is not uncommon, which is why we document it. Our workflow is designed for flexibility to allow you to generate code that can run on with any microcontroller or DSP - but you need to do the integration to bridge the gap between the code and the hardware you select.

Hello Brian,

Really Appreciate the work Mathworks is doing & making it easy to implement lengthy algorithms on different MCU's & DSP's.

Me Myself a huge fan of Simulink CGT...!

But it becomes sometimes very difficult to integrate(or bridge that gap) & leaves no choice but give up.Also very rare updates are provided for boards based on TI Technology.

I have worked on some 6000 series & MCU's(TIVA + MSP430) using Simulink Mathworks,which was very good learning experience.

Hope that TI & Mathworks brilliant minds might be working round the clock to fix what needs to be fixed to make it much easy & better.

Also Thank you for you kind Support, Means a lot.
