TMS320F28386S: Error caused by syscfg file.

What version of C2000WARE do you have installed?

Hi and thanks for the post.

The Resource explorer package mgr say I have

4.01.00.00
4.00.00.00
3.04.00.00

installed.

I must use CCS 11 and I import projects from 4.01.00.00.

John,

Does the error go away when you remove the pre-amble?

Regards,

Vince

I think if I remove it the syscfg file is not updated and the board.c and .h files are not added to the project. Also sysconfig complains that it does not know the software or device type.

When you added the SysConfig file did you follow the additional steps to setup your project properties identified here?

https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/910829/faq-how-do-i-add-sysconfig-support-pinmux-and-peripheral-initialization-to-an-existing-driverlib-project

This will resolve a lot of the issue you are facing.

Here is what is happening in your system currently (the post above will eliminate your error in any case but I want you to know what's happening):

When you add a SYSCFG file to a project, WITHOUT setting the PROJECT PROPERTIES as I showed in the the post above, the tool will look into the .syscfg file and parse that header that you have.

When it parses that header, it looks at the PRODUCT entry. The product entry is saying C2000WARE4.01. Well this may work and may not work... It requires that at one point the SYSCOFNIG tool which is integrated within CCS has used the C2000WARE 4.01 SW PRODUCT. If it hasn't it wont find it.

When you add the step #6 in the other thread I sent above, it will not try to FIND C2000WARE 4.01, instead it will directly reference the sdk.json file which you provide the path to.

Thank you very much for the post. I finally got it to work. At first by existing project, I thought you meant any. So I scrounged around and found a project than had a GPIO_setPinConfig() command in it and it worked.

Best wishes,

John

I hope this gets put in an app note for future users. I would have never figured it out on my own. I was using a workaround, grabbing the board.c and .h content and putting it in another file before removing the syscfg file so it would build.

Also I thank you for the explanation. To me knowing why is always better than being told just do it this way.

Absolutely I think adding it in an E2E FAQ or adding it to this https://www.ti.com/lit/an/spracx3/spracx3.pdf?ts=1670602542183&ref_url=https%253A%252F%252Fwww.google.com%252F

I need to import this project which does not have a .syscfg file. So I used the steps in

https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/910829/faq-how-do-i-add-sysconfig-support-pinmux-and-peripheral-initialization-to-an-existing-driverlib-project

for an existing project.

I do not get a prompt for enabling sysconfig if I add the empty .syscfg file via CCS but I do if I paste it in using file explorer.

Also in the sysconfig basic options I have:

[C2000WARE_INSTALL]/.metadata/sdk.json

However, after I Apply and Close and open C2000.syscfg I get:

Invalid argument '-s': File "C:\work\flash_kernel_c28x_dual_ex1_c28x1\CPU1_RAM\[C2000WARE_INSTALL]\.metadata\sdk.json" does not exist

In your project properties you already have an entry for SysConfig correct? That means the project already has sysconfig enabled.

For the second part,

"C:\work\flash_kernel_c28x_dual_ex1_c28x1\CPU1_RAM\[C2000WARE_INSTALL]\.metadata\sdk.json

This path looks wrong. What is the entry in the project properties that you entered?

Thanks for responding.

For the first part I deleted the project and re imported it.

For the 2nd part I entered

[C2000WARE_INSTALL]/.metadata/sdk.json

Can you share a screenshot of it? It doesnt look correct after the path is resolved.

OK, thought that was a system variable, thanks.

For the first part I had removed the project and imported again when it did not prompt for enablement.
