Problem with CAN interface when using eTimer

rafael_barbosa — Mon, 03 Aug 2020 10:26:40 GMT

Hello,

I am using the MBD toolbox 3.0.0 and the target micro-controller is MPC5744P. For the problem that I bring here, I am also using the PMIC 35FS6500.

My target is to use the etimer0 as a counter to measure the time between two interruptions and exchange CAN data in parallel.

I can send and receive CAN messages in the attached example when I delete (or comment out) the eTimer related blocks:

However when I include these eTimer related blocks in the model, the can messages does not works anymore in the target microcontroller.

Why is it happening?

I am using Canoe 11.0 from vector to exchange messages with the target microcontroller.

Kind Regards, Rafael

Hello rafael.barbosa@chassisbrakes.com ,

First of all consider installing our latest version of MPC toolbox (https://community.nxp.com/docs/DOC-346265 ) - the support for earlier versions will be limited.

Regarding your issue, I have a few questions: are you using a shared pin between eTimer and CAN? If yes, that would be a problem with our consistency check, as it should have warned you. Next, do you know if the application is still working after adding the eTimer blocks? Do you have a blinking LED or something to let you know? Or if you have put the executable in the debugger and saw the application is running normally.

Kind regards,

Razvan.

Hello constantinrazvan.chivu‌,

Indeed I am considering to update the toolbox for the version 3.2.0. It will be performed as soon as I reach the next project baseline. Thank you for point it out.

No shared pins between the modules:

PMIC pins for SPI: PTC7, PTC6, PTC5 and PTF3

CAN1 pins: PTA15, PTA14, PTD3 and PTD4

eTimer pin: PTC14

After adding the eTimer blocks the application runs. I am using the debugger (PE Micro).

I am intrigued what is going on.

Kind Regards, Rafael

Hello rafael.barbosa@chassisbrakes.com ,

Unfortunately due to our current workload it is hard to check this issue, given that it is in a version this old. Can you please check if you replicate this issue in the latest version? If the answer would be yes, we could give you a solution quicker for the v3.2.0 (than the v3.0.0).

Kind regards,

Razvan.

Hello constantinrazvan.chivu‌,

After the installation of the new version v3.2.0 this issue was solved.

The clock configuration updating

on the new toolbox version fixed the issue.

Kind Regards, Rafael
