MCR20A source migration from IAR to KDS

[DipenPatel1z]

Hi All,

In one of our design we are using MCR20A for 802.15.4 connectivity. But source (MCR20A_IEEE_802_15_4) for MCR20A is supported on IAR Workbench only. We would like to know how can we migrate source from IAR to KDS?

Also there are pre-built MAC libraries in MCR20A_IEEE_802_15_4\ieee_802_15_4\Lib\ folder. Is there a way to rebuild them? I couldn't find any project file under MCR20A_IEEE_802_15_4\ieee_802_15_4\?

Is it possible to achieve? Appreciate your response.

Regards,

Dipen Patel

Hello Dipen,

IAR EWARM and KDS have very different toolchains and development frameworks, so there is not an automated process to convert projects between these IDEs at all. The normal procedure would be to create a new project in KDS and import all the required source/header/ files from the example project you need. However, we do not have any examples or guidelines about this.

Hello Angel,

Can the IAR mcr20a examples be converted to KDS?

I see compiled .a libs such as Freescale_802.15.4_MAC_06_M4_IAR.a in the C:\Freescale\MCR20A_IEEE_802_15_4\ieee_802_15_4\Lib.  Are these for IAR only or can I just use them with KDS?

I have a couple of FRDM-K64F and FRDM-CR20A pairs and have them working but I need to build with KDS.  Would the steps be:

1- with KDS 3.0 create kinetis project

2- use KSDK 1.1.0

3- copy Sources from working example

4- set paths and symbols for the needed C:\Freescale\MCR20A_IEEE_802_15_4 dirs as well as other needed dirs

5- use Freescale_802.15.4_MAC_06_M4_IAR.a libs even though they say IAR in the name

Is there a set of KDS 3.0 Freescale_802.15.4_xxxx libs that are gcc compiled for us mere mortals to use with the KSDK 1.1.0 and this mad quest?

Thanks,

David

Hi David,

Yes, It is possible to  convert  IAR MCR20a  to KDS.

We have recently done it for FRDMK22F/KL26.

Please go through with  my previous post . Hope this will help you.

Thanks,

Sunil

Hello Sunil,

Yes it helped and thanks for posting your work.

My target is just the already working FRDM-K64F and not a port to a new chip as you have done.  I'm just bumbling along with the FRDM-K64 + FRDM-CR20A and have sensor data coming in and out via an embedded tornado server.  All so far is with the IAR stuff.  Alas, of course, to expensive for me and so I'm working on the K64 + CR20A mywirelessapp example with KDS 3.0 and KSDK 1.1.

Are you using KDS 3.0 and KSDK 1.1 ?

Did you link to ..\ieee_802_15_4\Lib\Freescale_802.15.4_MAC_06_M4_IAR.a ?

Thanks,

David

Hi David,

We used  KDS 3.0 and KSDK 1.2.

We did't link \ieee_802_15_4\Lib\Freescale_802.15.4_MAC_06_M4_IAR.a  and  it is not required.

It would be bit simple  for K64 because there are no pin mux changes are required in board files.

Just you need to set the source path of K64 which is available on KSDK1.2

I did't check it with KSDK1.1.

Thanks,

Sunil

Hi AngelC,

I am also working on the same thing.

Means ,We need to import all source code to KDS and compile it  ?

I found that  mcr20a source package is for K64 and we are using K22, So How can we migrate it for K22F ?

Would be great help if you can share some guideline for us. its  bit urgent.

Regards,

Sunil

Hello Sunil,

There is not any straight-forward process to migrate a solution from K64 to K22, although it should be possible in theory.  We have not done such thing with MAC examples so I could not say it is possible or easy to do. However, using KSDK should make it simpler. I could only recommend you to try it and verify whether it works or not. Sorry for the inconvenience.

Hi AngeIC,

Thanks for this input.

Hi AngleC,

We are able to migrate MCR20A source IAR to KDS environment.

Below are the steps:

1-Create a New Project for  K22F.

2-Open the pre-build application in IAR Workbench, and copy all the files which  are used in     application in single directory "sources".

3-Then copy the board related files (Ex: Board.c, Board.h, gpio_pins.c, gpio_pins.h, pin_mux.c, pin_mux.h) from C:\Freescale\KSDK_1.2.0\examples\frdmk22f on the "sources" directory.

and modified the following files:

Board.c :

void BOARD_InitXCVR(void)                                             //Added start point

{

gpio_output_pin_user_config_t xcvrResetPin =

    {

.pinName = kGpioXcvrReset,

.config.outputLogic = 1,

.config.slewRate = kPortSlowSlewRate,

.config.driveStrength = kPortLowDriveStrength,

    };

    configure_xcvr_pins(0);

    /* Reset XCVR */

GPIO_DRV_OutputPinInit(&xcvrResetPin);

GPIO_DRV_ClearPinOutput(kGpioXcvrReset);

GPIO_DRV_SetPinOutput(kGpioXcvrReset);

PORT_HAL_SetSlewRateMode(PORTD, 5, kPortSlowSlewRate);

}

                                                                                                // Added end point

void dbg_uart_init(void)

{

// configure_uart_pins(BOARD_DEBUG_UART_INSTANCE);              //Commented

// DbgConsole_Init(BOARD_DEBUG_UART_INSTANCE, BOARD_DEBUG_UART_BAUD, kDebugConsoleUART);                                 // Commented

Linker changes :

Now, Add the below flag in linker in project setting.

-specs=nosys.specs -specs=nano.specs -Xlinker –defsym=__ram_vector_table__=1

We have tested it to run send and receive demo application and verified it.

If you can spare your some time to validate the changes/inputs then that would be the great help for us.

Thanks,

Hi,

I don't have lot of experience with IAR tool but I know you can run IAR under Eclipse too.

This could be a good way to move the IAR workbench project to IAR Eclipse and at the end more easy to convert it to KDS.

This could help you:

Hi Pascal,

I have already referred to that link but it relies on IAR Workbench installed on your system. So not much helpful. Thanks for your response though.
