Problem -
Unable to use RappID BL to download the program to the microcontroller after generating code successfully using Simulink. Screenshot attached below.
Hardware -
I am using XPC56XX EVB motherboard (Rev.B) + SPC56EL 144 pin ADPT board (yes it's a mini module from ST microelectronics) + MPC5643L (144pin).
The code is to be programmed using CAN. So I am using a CANcaseXL (Vector) and CAN cable (with 120ohm terminator at the target side). This hardware is detected correctly and driver is installed correctly.
The jumper settings - I have tried ABS0=1, FAB=0, ABS2=0 ; ABS0=1, FAB=1, ABS2=0 ; and a few more combinations (ofcourse the combination that the tool also suggests). Attaching an image and also the user manual taken from the RappID BL tool itself.
I would like you to please help me confirm these jumper settings? I also understand that MPC5643L has a fixed baud rate. So from my understanding, the combination should be ABS0=1, FAB=0, ABS2=0.
I am using CAN (H) port and have enabled this using the jumper settings from the XPC56XX EVB document - Attaching a screenshot of the jumper settings - J27 is 1+3, 2+4. J28 is enabled. This is something I also would like to confirm. I am not sure if I am missing any other important jumper settings on the board but it looks complete to me.
Software -
From the Simulink, I am attaching the screenshot of the settings used in the block. Also I am just using the simple CAN example.
I don't know what the problem is but I am getting frustrated with it :smileyhappy: I am grateful for any help. :smileyhappy: Thank you so much.
P.S - Also I m currently using CodeWarrior compiler trial version (shouldn't matter in theory). And the motherboard+controller is NXP and the mini-module is ST micro's :smileyhappy:.
Hi raghurajappa,
Let's try to see if the CAN works and if you get's any messages from the MCU.
First, open the can_simple_block model from examples and configure it to download the code via UART (I presume you have a sort of UART2USB converter or something) similar to allow you connect you HOST PC with the BOARD via DB4 connector.
The Simulink model should be configured as: (just change COM port number to reflect your settings)
(use the model attached as a reference)
Once you download the model to the board into the MCU FLASH memory, then you should see some CAN messages over the network.
This will validate than the CAN setup is correct and the Vector CAN device works fine. Can you confirm the receiving of the CAN messages in this setup?
Thank you!

Hi Daniel,
(Had been a little busy doing another task). So I tried to connect my USB-UART (COM4 port) and it seems like the interface is detected but the baud rate is wrong. Attaching the image. But that Baud Rate number looks crazy big. I did some calculations and that insane baud rate number does not even exist. I am not sure where I am going wrong. It looks like a small step forward but now with a slightly newer error. The old error with the FAB,ABS and ABS2 pin configuration being wrong still occurs (after I click OK on the baud rate error) but I am guessing this should be solved if the baud rate is correct (which also does not make complete sense because the two errors are un-related as per my understanding).
Summary - We have a new error and it's Baud rate mis-match.
I am getting a new error. :smileysad:
I fixed this issue but the old problem still persists. :smileysad:
This is with integration into Simulink but even when I try the standalone BL tool, I get the same error as before.
Hi Daniel,
Thank you for your reply.
In my case this time though, I checked the voltages and it is correct. Attaching the 10K resistance circuit. The pull-up and pull-down should work as intended (atleast from the hardware perspective).
So the problem remains unsolved. :smileysad:
