MSPM0G3507: CAN tx example on early samples

Hi Thomas,

As you said, you use CCS12.3 for development.

So, are you using production sample for developing now? We recommend customer using early sample with SDK 0.58.xx or newr with CCS version lower than 12.2 (not included 12.2).

If you have production samples now and want to develop it, please download SDK 1.00.04 or newr directly in ti.com.

If you are ready for the previous preparation, the SDK will include the initial configuration of sysconfig. Try to use the example code and then modify it according to your demands.

Then if the error insists, feel free to give me some feedback. And I can do some verfication.

B.R.

Hello Sal,

thanks for your answer

Maybe it's confusing, I write that I have CCS12.0 + early samples, but in the past (previously, not the case now), I wrongly used CCS12.3

With previous config CAN was sent, now with correct CCS it's not

The check you request is precisely what I did here

Hi Thomas,

Actually, I am concerned about the device and SDK version you are using currently.

Is it production samples? Or just the same with the previous device. Can you describe the silk screen of the device or LaunchPad version you use now. So I can quickly get the answer of it.

What is your SDK version using currently?

I have SDK 0.58 and CSS 12.0.0, working fine with the early samples

Hello Sal,

here is my config

And regarding CAN I tested the same HW with wrong CCS thus it's working well, CAN is on pins 7/8

Hi Thomas,

In a word, the config of your HW is not supported for CCS 12.3. Details refer to following thread: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1204644/faq-mspm0-sdk-important-note-for-early-mspm0-customers 

If you want to use CCS12.3, please get "SDK 1.00 + production sample", other HW is not supported.

So, it works fine in "SDK 0.58 + CSS 12.0.0 + early sample", this is what I get in your description.

Hello Sal,

I don't know how to explain better, let me try a different way

1- early samples + CCS12.3 --> CAN frames emitted well but there are other problems (not CAN)

2- early samples + CCS12.0 --> CAN frames not emitted but oscillators are fine and it's the correct CCS

Is it clear?

I then suppose there is something wrong with CAN configuration in step 2, this is where I request help and why I posted my CAN config to check if something is wrong or not

In the meantime I try to retake CAN FD message

Hi Thomas,

Thanks for clarification. I get it clearly now.

Let focus on step 2 and figure it out. I will check the SDK example and then do some test.

I will give you the feedback as soon as I get some results. It will take a few time for the goal. Please let me know if you have any updates.

Hello Sal,

thanks a lot - btw there is one wrong statement, pins of CAN I use are 16/17 on 32 pins package

I try to play with the example, I set a timer that will send the frame every 100ms, I can see from debugger that it's called correctly every 100ms

The question is now to know why the frames are not emmited

Is there a document that explains the effects of all the configurations in mscan in syscfg, please?
