TMDSCNCD28388D: Unable to boot from flash at power on

Hi 

I have contacted MathWorks team to help us here. We should expect response by tomorrow.

Hello,

I cannot try 'removing the power supply and restarting the program' as I don't have hardware with me currently.

But can you please make sure that both models (F2838x-M4 and F2838x-c28x) are running with the 'Boot from flash' option checked?

And before build, load and run the F2838x-M4 model, a model with 'Boot from flash' must be running on F2838x-c28x CPU1.

Thanks,

Dhanashree

Hello,

Yes, the option is checked in both models and there is already a model with 'Boot from flash'.

I noticed that in the datasheet of TMS320F28388D in the table 8-15 it is said that in order to boot from flash the arm core I need to edit the registers CPU1TOCMIPCFLG0 and CPU1TOCMPICBOOTMODE.

How can I do it in Simulink? Assuming that it may resolve the issue.

Do you have other suggestions?

Thanks,

Jacopo

Hi,

Can you please share the sample models? And which MATLAB release are you using?

Thanks,

Hello,

I'm using MATLAB R2021a.

You can find the models here: https://drive.google.com/drive/folders/1iteOQt6oVlpKgp47D67lqolR5QVuJQ18?usp=sharing.

Hello,

For me, it is working fine after changing the switch S2 position.

Can you please make sure the switch S2 is as per the attached image?

Thanks,

Dhanashree

Yes the switch has the same position:

I'm sending you some images:

The output of some pulses produced by the CPU1 (blue) and the ARM (yellow) misured with an oscilloscope correcly before reset

Did you get any chance to look at this? Any thought?

Hi Jacopo,

Can you please try to load and run the TI example with boot from flash setting? Is it working fine after reset?

Thanks,

Dhanashree
