C2000 SVPWM with Simulink Error

Hi there,

I want to generate SVPWM - gate signal from C2000 TMS320F28027f for an inverter via Matlab/Simulink. When I settle my model as below, it is working.

But when I settle my model as below, it is not working.

I am facing that error message:

extra software will be generated to force this larger word or multi words to emulate a smaller

on the final production target, then consider increasing the word size to
one that is supported.

Is there anyone who knows the solution of this error?

Sorry for my bad english.

Hi Cati

Im building a SVPWM with VOC on a rectifier, but now im struggling with the connection between Space Vector Generator and ePWM, could you please give me a short guide? this is my email: [e-mail]

I appreciate your help!

Hi,

Error message you are getting is about insufficient memory. On TI C2000 processors, there are two different options:

1) Load program to RAM

2) Load program to FLASH

From the error message it looks like you are using the RAM version. To load the program to FLASH,in Model Configuration Parameters-> Code Generation->Coder Target-> Target Hardware Resources->Board, select TI F28027 (boot from flash) as the target. This will load the program to Flash and .cinit section also will use the Flash memory.

Another option is to modify the memory for each sections for your application. This is possible from the Memory and Section tabs in the Target Hardware Resources pane. Please look at section 8.5 of www.ti.com/lit/ug/spru513l/spru513l.pdf to know more about linker command file settings.

Hope this helps. Let me know.

I encountered the same problem, and adopted the first one to change my configuration. Luckily, it worked.
