UART KL05Z and Termite 2.9

[nguyennhatminh]

Hi Pro,

I'm using KL05Z and codewarrior10.6 to communication with the computer.

I wish to receive the character from Computer and send back by Termite.

My program has some problem that I can't solve it.

I tried to debug and found this error

No source available for "__udivsi3 (0x00000828)() "

in init_uart0 function.

Please see attached file for my project.

please help me on this issue.

Thank a lot.

Hi Nhat Minh,

    I checked your project, but I didn't find your error"No source available for "__udivsi3 (0x00000828)() ". it stop in  uart0_init function.

    I think it is the configuration error.

    Now, I do a uart project based on PE of Codewarrior 10.6. and it works OK.

    Please find my project from the attachment.

    My project function is : when receive the character from Computer and send back.

  My test platform is FRDM_KL05.

  UART BAUD IS 9600 bps.

  The test result is as follows:

  Wish it helps you!

If you still have question, please contact with me!

Have a great day,
Jingjing

Hi Jingjing Zhou,

Thank you very much for your reply and giving me the sample project with PE.

But , can you help me to have look my project and help me point out the error ?

I'm newbie to ARM. I read very carefully driver UART sample code and USER manual to do this project.

But I don't know what is real problem.

Your help will be highly appreciate,

Thank you,

Nhat Minh.

Hi Nhat Minh,

      You project is incomplete, you didn't configure the mcg clock,  the core clock, peripheral clock ect, and this is the most important to the cup.

      Attached is a new prject, and the main is neally the same as you, just add the sysinit() to configure the system clock, for details, please see the sysinit function.

     Besides, you need to read the MCG chapter in our reference manual.

    My baud is 19200 bps, and the test result is as follows:

Wish it helps you!

If you still have question, please let me know!

Have a great day,
Jingjing

Hi Jingjing Zhou,

thank you for your support,

I'm study MCG clock .

Your project that you sent to me , I can't run it.

It gives me the error "

mingw32-make: *** No rule to make target `F:/KinetisCode/practice/KL05/KL05_bare_uart/src/projects/LED_Blink/LED_Blink.c', needed by `Sources/projects/LED_Blink.o'.  Stop.    LED_Blink             C/C++ Problem

I think it relevant to the Path of the file 'F. 'put the project file in working directory but it doesn't show such as E:/...

Please help me how to correct this issue,

thank you,

Hello Jingjing Zhou,

I hope you are well.

As you told me I didn't configure the Clock for the system. So I read the mcg.c and copy the function and create the MCGOUTCLK for Core, bus,.. as below

SIM_SCGC5 |= (SIM_SCGC5_PORTA_MASK |SIM_SCGC5_PORTB_MASK);

       fei_fee(32768, 1, 1);

       SIM_CLKDIV1 = ( 0

                              | SIM_CLKDIV1_OUTDIV1(0)

                              | SIM_CLKDIV1_OUTDIV4(1) );

But the file still doesn't work, and I recognize the hex file wasn't  created. ( I set Create Flash Image).

So that to Create Flash Image file what compiler need is ?

In practical, I think NO ONE like me create a separate project like this , doesn't it ?

Would you like share with me your produce make a new project that based on Diver Class also create a new driver ?:smileysilly:

Thank a lot ,

Nhat Minh.

Hi Nhat Minh.

     Sorry for my later reply!

     Your configuration is still not enough.

     Please follow the sysinit.c in the KL05_bare_uart.rar  which I give you step by step.

    This file is do the system init, your system is not configured OK!

    Actually, you can use the sysinit at first directly, just add this file and the according head files.

    you can create a new project, and then add my file to your project.

   Wish it helps you!

Have a great day,
