MQX and Kinetis Design Studio as working

[kevincarcel]

Hello at present, I'm trying to work with the new develoment tool "Kinetis Design Studio". I want to develop an aplication with MQX in the FRDM-K64F.

I've tried to create a project MQX in KDS for differents ways:

*Create a project in Codewarrior 10.6 and import to KDS.(not compile)

*Create a project in KDS with/without Process Expert and KSDK.

*Create a simple project with Process Expert and KSDK, and include the component MQX and MQX task in my project.

Of the last two forms, I get to compile without errors, but i can't debug. Show the error "Can not read register XX (XX) while CPU is running".

How can i work with KDS and MQX? How can i create a MQX project?

Thanks for the help.

Could it be that the code for FLEXCAN_DRV_IRQHandler is not linked?

That would explain why the breakpoint settings fail.

Can you check in the linker .map file that this function indeed is linked?

hello Luis and Erich

thanks for your help. I've reviwed the file .MAP and the interruo handleris inclose.

I attach the file .MAP for if it is helpful

hello Luis and Erich

I attach the file logs when download de code in the board and when I add a breakpoint for if it is helpful.

Hi Kevin,

Perhaps is better if you post the project.

Hi Luis

I attach all folder of eth_to_serial example with all files. My project is for the board FRDMK64F

Thanks

Hi Kevin,

I can debug your code

There are multiple issues (Watch and read the Warnings, they are also important). Basically you have many implicit function calls, aka, it has not been resolved by linker. You need prototypes of functions in header files, for example:

void IniciarCAN(void);

And I have commented out all the ‘printf' as they are also implicit calls.

But the more important issue is that you have a function static void init_hardware(void) that is also included in the MQX BSP. I have not investigated why GCC linker doesn't complain, but removing the function, it works.

Hi Luis

I also could debug and add breakpoints in the function IniciarCan(), but I don't add a breakpoint in the interrupt or interrup handler.

void CAN0_ORed_Message_buffer_IRQHandler (void)

o

void FLEXCAN_DRV_IRQHandler (uint8_t ejemplo);

I've added your changes, but I can not.

Thank you very much Luis.

Hello,

I think that code isn't linked in the application. You're not installing the CAN interrupts in the MQX application.

Hi Luis

I added the libraries in the option project.

How can it keep happening? How can I install the CAN interrupt?

[LuisCasado]

Hello,

In MQX (any version) you need to install the interrupts _int_install_isr

Thanks in advance.

Hi,

your path is "C:\Freescale\Freescale_MQX_4_1_1" not "C:\Freescale\Freescale_MQX_4_1", so change MQX_ROOT_DIR accordinly.

Hi Luis

Yes , my path is MQX_4_1_1,  and so  in the .cproject  file i already  write accordingly like the screenshot below .

And  the attachment is the .cproject file.

Thank you !

Hi,

Attached a project I created, change the path to 4_1_1 and try it out.

Luis

[Alice_Yang]

oh, sorry  luis,  the project can work normally now .

Hi luis,

I  put your project on the desktop, and build it use kds 1.1.1 ,while it still have error , i need your help .

Thank you !

Hi Kevin,

For the debug configuration you can refer to the kds_user_guide(C:\Freescale\KDS_1.1.1\doc\pdf\kds_user_guide.pdf) about   "4 debugging an embedded application"

and  kinetis SDK k64 User's Guide (C:\Freescale\KSDK_1.0.0\doc) about ( 4.4.3 Run a demo application)

Hope it helps

Hello kevin,

MQX 4.1 does not have KDS project files included.

Official support of KDS in MQX is planned in MQX 4.2 & MQX 5.0 coming later this year.

At that time MQX plug-ins for KDS (e.g. Task Aware Debug & New Project Wizard) will be available.  Also, MQX project files for all libraries and examples will be available for KDS. 

In the meantime, I recommend to make a copy of an existing demo or example and edit this project. You can find them in the following paths.

C:\Freescale\MQX_KSDK_1.0.0\demos

C:\Freescale\MQX_KSDK_1.0.0\rtos\mqx\mqx\examples

Compiling MQX Libraries and Demos for the KDS  you can refer to  Compiling MQX Libraries and Demos for the KDS Toolchain.

Best Regards,

Alice

Hi Alice,

MQX 4.1.1 does include support for KDS.

From release notes:

Freescale MQX RTOS was compiled and tested with these development tools:

• Kinetis Design Studio version IDE 1.1.0

• Support available for Kinetis devices

• See build projects in the Kinetis Design Studio

subdirectory

• Makefile build option: TOOL=kds

Hi Luis and Kevin

There are many demo about  MQX + KDS under MQX4,1,1, while it seems that in KDS can't creat project like CW(file->new->mqx project), so in my opinion,  make use of the demo under the mqx is a good choice. what do you think?

Best Regards

Alice
