SD card interfacing with KL25Z

arthshah — Tue, 25 Apr 2017 06:26:58 GMT

i am trying to port fatfs to Sd card.

i refer this link https://community.nxp.com/docs/DOC-330958

now my question is that which file i need to added in my project

because in main() function no any spi related function are call.

assign to @TIC kerry

If you do get tired of trying to piecing together incomplete examples, do remember that you can download a full KL25 solution with SD card (via SPI), memory stick (via USB-HOST), which also works as USB-MSD to SD card or internal Flash (optionally as composite with various other USB classes). Its integrated FAT [http://www.utasker.com/docs/uTasker/uTasker_utFAT.PDF] has more features than fatfs and you can simulate all operation in Visual Studio to maximise learning and/or development efficiency.

Web:      https://github.com/uTasker/uTasker-Kinetis
HTTPS:    https://github.com/uTasker/uTasker-Kinetis.git
SSH:      git@github.com:uTasker/uTasker-Kinetis.git

FREE, documented and with numerous videos to see it working and to get started quickly.

Allows immediate operation on about 50 Kinetis boards (KE, KEA, KL, K etc.), builds with 10 IDEs, requires no porting and no lost time.

thank you mark,

i am trying to port fatfs in sd card kl25z.

i don't understand utasker.

so i want to use KDS for my project.

uTasker works with KDS. If you follow this video you could finish your work in about 20 minutes.

For FRDM-KL25Z with full SD card interface, plus USB-MSD, simply enable in config.h:
- FRDM_KL25Z
- SDCARD_SUPPORT
- USB_INTERFACE + USE_USB_MSD

and build.

hii mark,

thanks for the reply.

please give me download link of utasker and how to use it ?

Re: SD card interfacing with KL25Z

mjbcswitzerland — Fri, 28 Apr 2017 19:13:46 GMT

Download links have already been given - it is on GITHUB, where the open source project version is maintained.

Video for GITHUB and KDS has already been given.

hii Mark,

i downloaded utasker from link provided by you.
when i unzip that zip file there are many folders.

i attach here screen shot of that file please tell me what i do next?

Thank you.

Re: SD card interfacing with KL25Z

mjbcswitzerland — Sat, 29 Apr 2017 12:09:18 GMT

To open with KDS follow the KDS guide: http://www.utasker.com/kinetis/compilers.html#KDS
and/or follow the video https://www.youtube.com/watch?v=K8ScSgpgQ6M&t=311s
There are also a short guide in "readme.txt" file that you have shown.

hello mark,

i have done as u ask for, but i still can't import utasker project into my KDS.

please help me to solve this problem.

Re: SD card interfacing with KL25Z

mjbcswitzerland — Thu, 04 May 2017 11:34:01 GMT

The KDS project settings are in the folder \Applications\uTaskerV1.4\KinetisDesignStudio\Project_Settings

These were available in the "Development" branch but I just merged back to the master branch so if you check out from the master the will now be there too.

Copy the contents of this folder to the root directory and then import the root directory path into KDS.

Mark

hello mark,

thanks for reply.

i already done what you ask for.but still not getting success.

Re: SD card interfacing with KL25Z

mjbcswitzerland — Thu, 04 May 2017 12:55:22 GMT

I just tried now and had no problems.

Please tell me what the problem is because without knowing what doesn't actually work (can't you import, can't you build etc.?) it is impossible to give specific help.

hii Mark,

thanks for reply

My problem is i can't import utasker project in my KDS.

Re: SD card interfacing with KL25Z

mjbcswitzerland — Fri, 05 May 2017 13:53:09 GMT

I am sorry but I have just tried again and can't detect any problem. Are you following the documentation and video correctly?

I do this (exact steps):

1.I made a directory to work in - say "MyProject"
2. I now clone the Open Source Git repository and it has the folder "uTasker-Kinetis" in it now. I use TortoiseGIT but any GIT client can be used.

3. Since I want to use KDS I copy the content of the folder "MyProject\uTasker-Kinetis\Applications\uTaskerV1.4\KinetisDesignStudio\Project_Settings" to "MyProject\uTasker-Kinetis" so that the KDS project files are at the root.

4. I start KDS and tell it to use a new work-space - say "development"
5. I import the project from the toot directory, that is "MyProject\uTasker-Kinetis"

Then I have the project open in KDS and can continue with building the configuration that I want.

Since I have tested a few times I can only conclude that you didn't follow one of the steps correct. Please do the 5 steps exactly and then you should have no further problems.

Mark

Hii Mark,

Actually i can't understand your 2nd step.

I just download utasker from link provided by you..i don't know about GIT clone or etc..

And except 2nd step i follow all step perfectly..

Please help me for utasker download nd about clone.

Thank you for the reply.

I use TortoiseGIT (see the video) but also just downloading the .zip file from GITHUB will work (rather than working with a GIT client). However it is advisable to learn GIT since it is used by many projects and simplifies firmware management.

This is the content of the root directory, whereby the files .cproject and .project are from KDS (copied from the KDS folder) (the .git folder is normally invisible and won't be there if you don't use GIT):

If this is given as path to import to KDS I don't know why you can't import it. I have never heard of anyone who couldn't import it before.

Please show a screen shot of the import attempt.

Regards

Mark

arthshah — Sat, 06 May 2017 05:16:57 GMT

hii Mark,

thanks for the help.

here i attached my screen shot of KDS project setting.

it,s path is

C:\Users\RND1\Downloads\uTasker-Kinetis-master\Applications\uTaskerV1.4\KinetisDesignStudio\Project_Settings

From this path i just copied .settings folder and paste it to root directory.show below screen shot.

In my project there is no .cproject and .project file.

i download utasker from link provided by you.

Thank you.

hello Mark,

i Re downloaded the utasker.

my problem is now solved.

thanks for the help.

Now i want to SD Card as a MSD with KL25Z how it is possibal with utasker?

give me some idea about that.

Re: SD card interfacing with KL25Z

arthshah — Sat, 06 May 2017 07:04:41 GMT

hii Mark,

As you said in earlier post i followed the same.

For FRDM-KL25Z with full SD card interface, plus USB-MSD, simply enable in config.h:
- FRDM_KL25Z
- SDCARD_SUPPORT
- USB_INTERFACE + USE_USB_MSD

and build.

when i build the project there are error like '_port_D_isr' undeclared (first use in this function)

Now, what should i do ?

and where is the Main file of the my project?

Re: SD card interfacing with KL25Z

mjbcswitzerland — Sat, 06 May 2017 14:24:39 GMT

Unfortunately there is a 'typo' in the file "kinetis_PORTS.h" which affects the KL25 configuration.
Please modify:

#if (PORTS_AVAILABLE > 3) && !defined NO_PORT_INTERRUPTS_PORTD && defined irq_PORTC_ID // if port D support has not been removed
to

#if (PORTS_AVAILABLE > 3) && !defined NO_PORT_INTERRUPTS_PORTD && defined irq_PORTC_ID // if port D support has not been removed

I have corrected this in the repository.

extern int main(void) is located in the file kinetis.c. This is however used to control the scheduler and user code is in tasks.

The application task in application.c [extern void fnApplication(TTASKTABLE *ptrTaskTable)] starts the mass storage task (controlling the SD card interface) and the USB task (controlling USB-MSD).

The following documents describes the scheduling operation and give a guide to new users who may not yet be used to writing code for scheduling systems - it is much more powerful and flexible that round-robin main loops but requires a little re-thinking. After a little experience it will prove to be more practical and efficient.
http://www.utasker.com/docs/uTasker/uTaskerV1.3.PDF
http://www.utasker.com/docs/uTasker/uTaskerV1.4_user_guide.PDF

Once you run the code on the board you will find that the SD card is mounted automatically (background operation) and the USB-MSD interface will also signal when it is mounted to the USB host. This is automated you you don't need to write code to do it.

On the OpenSDA VCOM interface (115200) you can test FAT and low level SD card operations in the utFAT menu, which looks like this. Of course you will need to wire up to an SD card correctly otherwise it will say that there is no SD card present until it is detected.

In case you prefer to see operation without SD card first, simply comment out SDCARD_SUPPORT and comment in SIMPLE_FLASH and it will perform the operations in internal Flash instead.
