modify the .lcf file and .tmf file result the program can not run

hongjinzeng — Tue, 23 Jan 2018 02:22:41 GMT

Hi everyone,

Now I use the MCToolbox with MPC5643L.In the model I use FlexPWM without any modify,the program can run.When I modify the rappid_564xl_cw_flash_2013.tmf and the MPC564xLFLASH.lcf,the program can not run.

In the rappid_564xl_cw_flash_2013.tmf file,I modify in the below:

In the file I delete the '-romaddr 0x00003000 -rambuffer 0x00003000'.

In the MPC564xLFLASH.lcf file,I modify in the below:

In the modify file:

the old .lcf file

After I build the model,I debug the program by S32DS.

First I set breakpoint in the below:

In the debug process.First I click the run button, the program go to the bteakpoint.Second I click 'Step over' button twice,the program only run one step and in the next step the program run to the 0x0.

I do not know how to solve the problem,can you help me?

Hi hongjin zeng,

Can you tell us what are you trying to achieve ?

Why do you need to change the default memory layout ?

Thank you!

Daniel

I want to write a CAN flash bootloader,so in the application software the memory layout need to modify.

Hi hongjinzeng‌,

I'm going to check today - and let you know.

Best regards,

I'm not an expert in how this processor works but i think that might be a potential culprit for the S32DS behavior you are seeing with 0x0 jump.

So, for the Simulink model settings i see no issues - the only questionable thing is the linker command file mapping. My advice is to get in touch with https://community.nxp.com/community/s32/mpc5xxx community since there are experts in MPC series. I think at this point is just a matter of setting the memory map correctly according with MCP5643L restrictions (which unfortunately i'm not fully aware off)

Hope this helps!

Daniel

Hi popa,

Thank you for your reply.Should I ask the question in MPC5XXX community?Or can you help me ask the MPC5xxx community?

Re: modify the .lcf file and .tmf file result the program can not run

My suggestion is to ask on MPC5xxx community directly and provide just the CodeWarrior project you are using. There is no direct cross-reference between communities, the persons that are visiting that space might be totally different than the ones interested in Model-Based Design Tools community.

In my opinion - your question have more chances of being solved there since it is about setting up a custom project. It does not matter how the C-code was generated (manually of automatically). You also proved that is works with default memory layout - so it should be straightforward for someone who has knowledge on MPC5xxx.

Also, in that community i see there are a couple of issues related with custom boot-loaders for such processors.

Best regards,
Daniel
