Using RAppID with MPC5744P and CAN

[andremeyer]

Dear all,

I am try to flash the MPC5744P via CAN using the RAppID tool but I always get an error --> CAN error frame received.

The hardware I am using is the the original EVB with 144p device.

CAN hardware is a Vector CAN Case XL.

First I flashed the 5744p.rbf file using our Greenhills environment.

The I configured the RAppID tool for CAN operation. The EVB has a XOSC of 40MHz therefore I set the Baudrate to 100000 manually inside the .rbl file.

When I press "Start Boot Loader" I can see CAN frames from PC to µC but no response.

Maybe the the application running on the µC is not working correctly or the clock setting is wrong.

Or do I need to the the ABS pins accordingly?

I hope someone can help me with my problem.

BR;

Hello,@andremeyer I'm also tried to flash via CAN0 to mpc5744P but I'm getting error like "CCP Communication Error. CAN port not open".  Can you please suggest me what kind of setting required.

THANKS

Hi,

I managed to write to flash using the serial interface instead of the CAN interface.

After adding the "Application Key" and "Time value" the Application is starting.

With CAN communication I still got no respose from µC.

After flashing the MPC5744p.rbf file I checked the register setting and it seems that only the LINFlex_0 module is initialized.

Only SIUL2_MSCR18 and SIUL2_IMCR165 are setup for LIN_0. (PB2, PB3)

SIUL2_MSCR_16 and SILU2_IMCR_32 are not setup for CAN_0. (PB0, PB1)

Maybe CAN is not supported by this RBF file?

Hi,

I just got the feedback. Currently the bootloader for MPC574xP does not support CAN communication. There's a mistake in release notes. The support of CAN communication will be added in the future but the release day is not known yet because the team is working on other tasks right now.

Hi Lukas,

Currently does the bootloader for MPC574xP  support CAN communication?I am try to flash the MPC5744P via CAN using the RAppID tool but after programming the rbf file to MCU,I always get an error

Hi,

I shared the rbf file for MPC5744P above (https://community.nxp.com/servlet/JiveServlet/download/811936-1-382277/MPC5744P.rbf.zip). I got it from SW developers. I do not have tools to test it but it should work.

Can anyone confirm that the new rbf is working for CAN BL on MPC5744P? I've tested it but I'm getting the same error as @kuang yan. I'm using the dev board with vector VN1610, have done the vector hardware configuration, loaded the rbf (it works for serial communication), can see the CAN messages on the relevant channel when I load my app. 

Am I missing anything?

Hi,

Thank you very much for following up this issue.

I already started to build my own CAN boot loader based on your serial boot loader version for the MPC56xx.

Hello André,

just in case you still want to use rappid bootloader, attached you will find updated version that supports CAN 0 at 500K baud rate.

Hi:

   I am developing mpc5742p's  bootloader based on "serial bootloader for MPC5748G", when compile,the following error has been occured, how to solve these  errors?

[lukaszadrapa]

I just shared preliminary version of serial bootloader for MPC5748G in this thread:

How to debug bootloader code running on RAM

Maybe it will be useful. It's based on my previous bootloader for MPC56xx...

Hi,

I can see the same behavior on my side. It look like the CAN is not enabled ever.

I'm checking with Rappid team what's going on. I will let you know later.

Regards,

Lukas
