Could you please help me understand better? I basically have vector CANcaseXL connected to my computer and it is setup correctly (image attached below)
There are two problems I face at this moment.
1. But when I use simulink to generate code, the generation is successful BUT after this the RappID application does not open. Nothing happens after the code is generated. Ideally I expect the generated code to be compiled (I have DIAB compiler installed) and then the RappID BL application to open and program the microcontroller. This is the first problem.
2. Now as an alternative I am trying to open RappID BL application.exe (standalone) and then trying to program (first even testing the connection does not work) the microcontroller with some test applications. I am not sure what the problem is and that's what is troubling me. So both ways (standalone as well as integrated with simulink) I am stuck without much progress.
Also the RappID BL application does consist of newer software for the MPC564xL series of controllers (image attached just above).
Thank you for your support. :smileyhappy:
Hi raghurajappa,

Please select "Download Code After Build" option in the PIL/BAM Setup within the "RAppID_564xL_Config" This works only if you connect the MCU with the Host PC via UART. Application download via CAN is not supported in the Simulink.

Have you set the board correctly ? Please have a look here: where to look for MPC564xL.rbf file ?
Then, please refer to chapter 2.9 Enabling Vector Hardware from RAppIDBL_UserManual.pdf. Some additional information here: https://community.nxp.com/message/898475
Hope this helps!

Hi raghurajappa
I would like to use Simulink on one PC to generate code (and HEX file) and another PC somewhere else to flash this hex file to the microcontroller. But from what you explain, it looks like Simulink will not generate hex file without the hardware connected. Is this true?
This use-case it is perfectly supported by the Simulink. You can have the MATLAB/Simulink + NXP Toolbox on one computer and generate all the C/H/makefile/elf/mot files into a folder called ***_rtw that is placed in the current MATLAB path.
Inside this folder you can find all the generated files.
In my folder structures also I could not locate any hex files that I could use separately in my IDE. I did this as an alternative where I can use Simulink to generate hex files, then take these hex files into the CodeWarrior IDE (or FreeMaster) and use JTAG to program these. But I could not find the hex files.
By default the toolbox is configured to generate the *.elf and *.mot files
ELF is the standard DWARF format file that can be used in any IDE. You can use this file to load the application in the MCU with the available Debugger (that is DWARF compliant) via JTAG.
The hex file is special format that could be generated (by default the toolbox generates the mot file format) via 2 different approaches:
#1: starting from ELF you could use jfrey suggestion as here: https://community.nxp.com/thread/452609#comment-910812
#2: you could modify the toolbox makefiles to generate hex instead of mot as per paulvlase suggestion: https://community.nxp.com/thread/452609#comment-912694
Hope this helps!

Hi Daniel,
I tried it with the exact same example. Attaching the screenshot. I cannot find .elf/.mot files in there.
Everything else is the same. I have not configured FreemasterSetup or CCPSetup in the "Block Parameters" tab. But I find the generated code and everything else in there :smileyhappy:
Hi raghurajappa,
Have you configured the DIAB compiler ?
Here is my folder with the same setting as yours. Please find it attached.
Also, can you share your build log file, eventually as txt file ?
Here is how mine looks like:
Best regards,
Daniel
I was about you send you this information :smileyhappy: and you asked for it. It looks like the compile/link error exists but I could not figure out what the problem is. Does it have to do with the VLE enable option? If yes, how do I switch it off??
Hey Daniel,
Just when I thought it was all fine, I get this error from RappID.
So I have reached a point where I can generate elf and mot files from Simulink. But to use the RappID BL either standalone or integrated, I get this error - screenshot shown here.
Please note I have not yet connected the hardware to the UART. But even before I can do anything, this error pops up. Even when I do connect the hardware, the same error persists. So two things
1. How can I fix this error? (ofcourse)
2. Is there a document on how to use the RappID to get it up and running? I ask this because my UART interface does not get detected. If this problem is linked to the RappID error then it's alright but I am also making a guess that the problem occurs because UART device driver isn't there.
Hi raghurajappa,
Please note I have not yet connected the hardware to the UART
Please make sure you have at least one COM Port enabled and available on your PC. You should connect it to the board and power on the board. After that you'll have the RAppID BL running ok.
Best regards,
Daniel
