KDS 1.1.1 and MQX

[piotrek]

I would like to use MQX with my FRDM-K64F board projects.

I do have KDS 1.1.1 with KSDK 1.0.0 installed.

From the existing documents it it not clear to me if I need the Freescale_MQX_KSDK_1.0.0-Beta to be installed too?

Regards,

Piotr

It seems that every time there is an answer I find another question to ask.

So, maybe this will help to get the final answer:

When installing for the first time what steps/order should I follow to have KDS, KSDK, and MQX (with RTCS and MFS) ready for my FRDM-K64F development?

You need to install KDS 1.1.1: http://freescale.com/kds

Then install MQX for KSDK 1.0.0: http://freescale.com/mqx/ksdk

Then follow the K64 user guide at C:\Freescale\MQX_KSDK_1.0.0\doc\Kinetis SDK K64 User's Guide.pdf, specifically section 4.4.

Then you'll have everything you need for FRDM-K64F development with KDS+KSDK+MQX.

Hi Piotr,

  As you've seen, there are two ways to get MQX with KSDK right now with the 1.0.0 version.

1) KSDK Installation Package (MQX, FreeRTOS, uCOSII, uCOSIII)

Default Install Path: C:\Freescale\KSDK_1.0.0

Download from: http://freescale.com/ksdk

Includes KSDK+RTOSes Kernel

2) MQX for KSDK Installation Package (MQX only)

Default Install Path: C:\Freescale\MQX_KSDK_1.0.0

Download From: http://freescale.com/mqx/ksdk

Superset MQX package: Includes KSDK+MQX Kernel+RTCS+MFS

Both methods will get you all the features and files of KSDK. The only difference is the MQX for KSDK installation also includes the MQX MFS (Filesystem) and RTCS (Ethernet) stacks and does not include the FreeRTOS or uCOS kernels. MQX for KSDK is currently provided as a separate installer since it was released as Beta.

Also note that to get MQX when installing the normal "KSDK Installation Package", you must select the "Custom" installation and then on the next screen select MQX. After installation you'll see the MQX source at C:\Freescale\KSDK_1.0.0\rtos\mqx. If you do not see that folder, you'll need to re-install the KSDK package and make sure to select the "Custom" install.

When KSDK 1.1 is released in about a month, there will only be one installation package ("KSDK") and that should make it less confusing.

Hello Anthony,

I followed the way 1, KSDK installation, so I do have MQX but not RTCS and MFS installed.

What would be the proper way to add RTCS and MFS to my installation?

In describing way 2 you are saying:

"MQX for KSDK Installation Package (MQX only)"

and

"Superset MQX package: Includes KSDK+MQX Kernel+RTCS+MFS"

So, if it is MQX only why does it include KSDK?

Hi Piotrek,

At the moment the only way to get RTCS and MFS is to use the MQX for KSDK installer (the second method). This will change in the KSDK 1.1 release when everything will be in one installer package.

  For the second question, I say it's "MQX Only" because it does not include the other RTOS kernels. This MQX for KSDK relies heavily on the KSDK drivers and startup code, so they're very integrated together.

Did you install the released KSDK with the custom selection?  The MQX is one of the install options so I would think you wouldn't want the beta installed.  If you don't see MQX installed maybe you can run through the KSDK installer and reinstall it with the "custom" option making sure MQX is selected.

Good luck!

Hello Tim,

Freescale makes the two installers available: Freescale_KSDK_1.0.0 and Freescale_MQX_KSDK_1.0.0-Beta. I think it would be very beneficial to clarify:

1 - Why do we have two of them?

2 - Which one to use and when?

Regards,

Piotr

I see what you are asking now.  I think this quote from the MQX page answers your question:

"NOTE: Freescale MQX RTOS for Kinetis SDK is currently released as beta software at this time, and includes Kinetis SDK v1.0. The final release is scheduled for Q4 2014. MQX RTOS for Kinetis SDK is a separate software package and does not require prior installation of the Kinetis SDK."

Hi Tim,

So, what will we have in Q4 2014:

1. Two overlapping installers like today (with possible explanation when to use which)?

2. Separate installer for MQX and KSDK?

Well, the readme for MQX RTOS for KSDK say:

Freescale MQX™ RTOS for Kinetis SDK. The product is based on the MQX kernel, MFS
and RTCS stack version 4.1.0. The product is provided in two packages:

• MQX Kernel only – should be extracted to previously downloaded SDK 

• MQX pre-integrated package – already contains SDK,TCPIP stack, File system

Good luck!
