Is there a document detailing the use of the KSDK “I/O subsystem (NIO)” device drivers?

M_Grillo — Wed, 08 Apr 2015 19:16:54 GMT

"Is there a document detailing the use of the KSDK “I/O subsystem (NIO)” device drivers?"

Is there a document detailing the use of the KSDK “I/O subsystem (NIO)” device drivers? MQX 3.x.x to 4.x.x always had a documentation for I/O driver usage. I’m attempting to port an MQX K60 project over to the new KDS toolset for K64 with KSDK w/MQX that uses several UART ports and can’t find documentation or an example(s) using multiple UART ports (interrupt driven).

Is there a newer than 1.1.0 version release of KSDK pending that includes more documentation, driver support and examples?

Thanks,

Mark

Hello Mark,

Please check the Kinetis SDK v.1.1 API Reference Manual, you can find this doc at the path: C:\Freescale\KSDK_1.1.0\doc

Have a great day,
Sol

Hi Mark,

Yes - structure for MQX RTOS for KSDK is here:

I can recommend you Freescale MQX RTOS for Kinetis SDK User's Guide, which is actually located at C:\Freescale\KSDK_1.1.0\rtos\mqx\doc

and other guides, which can help you.

I hope this helps,

Have a great day!

Kind Regards,

Iva

Hello soledad,

Thank you for the reply. I did come across the UART Peripheral driver section in chapter 31. I’m trying to use MQX in the SDK package and MQX has a “NIO” higher level driver that sits on top of the SDK UART Peripheral driver package. I’d like to find documentation/examples on how to use the “NIO” drivers located in MQX. MQX appears to call the “NIO” drivers to setup the UART and other I/O with the “eth_to_serial” demo in “init_bsp.c”.

Is it Freescale’s intention to use the “NIO” drivers when using MQX rather than contend with the BSP initialization and by writing to the SDK/bare-metal drivers direct?

Thanks,

Mark

Hello Iva,

Thanks for the reply. 2.23 states: NIO “I/O drivers are not described in this book”. The elusive I/O drivers and I/O Subsystem(NIO) documentation is what I’m in search of.

Thanks,

Mark

Hello Mark,

for these facts you can look at Porting an MQX RTOS Application to MQX RTOS for Kinetis SDK, which is located at http://cache.freescale.com/files/soft_dev_tools/doc/support_info/MQXKSDKPUG.pdf

You can look forward to new document, which could be ready by the end of April.

Please, go to Freescale MQX™ RTOS for Kinetis SDK|Freescale and e.g. at http://cache.freescale.com/files/soft_dev_tools/doc/support_info/MQXKSDK110RN.pdf?fpsp=1&WT_TYPE=Supporting%20Informatio…

in tab Documentation, All Documentation,

is nicely described I/O drivers, in chapter 4.3.

Nowadays we have not such manual for KSDK.

Have a nice day,

Best Regards,

Iva

Hello Mark,

I checked the information with KSDK team and we really do not have such documentation.

Once this documentation is complete, or other material that you might find to helpful for you, I'll let you know.

Have a great day,

Best Regards,

IVA

Hello Mark,

I checked the information for you, and such document which you find we actually do not have.

Yes, it is plan for future. Actually in April is expected KSDK 1.2.,

so we will make the document after this release and I will let you know.

Have a nice day!

Iva

Hi,

The KSDK 1.2 is released, but I could not find any documentation regarding the design of nio?

PS:Is there plans for more nio-drivers? What I'm particulary want is a driver which could be

used by the 'tty:' to use USB-CDC as output, instead of uart....

M_Grillo — Wed, 03 Jun 2015 13:03:46 GMT

I could not find any additional documentation in KDSK 1.2.0 either. It is rather frustrating because what I have working for NIO UART drivers in KSDK 1.1.0 does not work in KSDK 1.2.0.

Hello Mark and Ole, I contacted NIO expert, please give me short time to find out the information. Have a great day! Iva

ivadorazinova — Mon, 08 Jun 2015 09:00:06 GMT

Hello Mark and Ole,

I checked the information for you and NIO documentation is not finished and actually we cannot say exact term.

Sorry for any inconvenience this may cause.

Have a nice day!

I just wanted to jump on this bandwagon. I was about to post the exact same question about I/O drivers with MQX/KDS.

Even incomplete documentation might be helpful?

I have been struggling to port a CodeWarrior MQX project to KDS with MQX. Now that I've seen this post, might be sticking with CodeWarrior after all.

Hi Iva,

Add me to the list of people who require this document :smileyhappy:

I'm trying to implement an NIO interface for serial flash (see here) and this document, even in its incomplete state, would be very helpful.

If there are no plans to release this document in the near future maybe you could put me in touch with an expert who could answer my questions?

Thanks!

Hello David,

yes - I understand, but it is unfortunately not possible.

For your last comment with migration - I do not know in which migration step you are and which issue you face, but

I can recommend you see following threads:

Hello Meric,

Thank you for the feedback.

I sent the information to SW team.

Actually I see, that your request is in progress by our expert now.

Please, wait for a response.

Have a nice day!

Hi Iva,

Is there any more word on this? I require the documentation too, as I have need of multiple serial communication channels in MQX. Is there anywhere you can point me yet?

Kind Regards,

Dan

Hello Daniel,

no, the only document for that is MQX RTOS I/O Drivers User´s Guide chapter Serial-Device Families, p. 59

I hope this helps,

Hi Daniel,

I have had great success using the full MQX 4.2.0 with KDS 3.0.0 toolset, (with the Kinetis TWRK64), rather trying to struggle through using the KSDK version of MQX. There are many examples for exercising all peripherals and features. The documentation and source code are very intuitive. Thanks to user ‘soledad’ for pointing out a document to creating a new MQX RTOS 4.2 project in KDS: https://community.freescale.com/docs/DOC-106217

I believe KSDK has great promise but isn’t quite ready for rapid development due to the examples and documentation haven’t caught up.
