bug in debug console for FRDM-K22F BOARD_DEBUG_UART_INSTANCE?

christophertsch — Thu, 15 Jan 2015 21:36:32 GMT

This is in KSDK 1.1.0 and I am wondering if this is a bug. I had to change the statement "#define BOARD_DEBUG_UART_INSTANCE 2" to "#define BOARD_DEBUG_UART_INSTANCE 1" in DbgCs1.h for my debug_printf command to write to 0x4006b000 instead of 0x4006c000 which was not working. I set the device to UART1 so that it would write to PTE0 so that I can use the pins that go to the UART that goes to the USB debug port but that was not sufficient.

can you upload your project here and depict how to reproduce your problem?

and what's your KDS version?

Best Regards,

Zhang Jun

KDS version is 2.0.0

It is probably easier to describe the steps.

1) I created a new KSDK project for FRDM-K22F (File-New-KDS Project-Clicked Processor Expert-Finish).

2) Double-clicked fsl_debug_console in Components Library to instance DbgCs1.

3) Click on DbgCs1 in components view and set device to UART1 in Component Inspector.

4) Set Rx/Tx pins are set to PTE1/PTE0.

5) Set baud rate to 115200.

6) Click "Generate Processor Expert Code" button.

7) Add #include "DbgCs1.h" to main.c

8) Add the code below to the main function

bool start = true;

for(;;)

{

if (start)

{

debug_printf("\n\r Process started\n\r");

start = false;

}

9) Start terminal emulator to communicate with com port associated with USB port connected to FRDM-K22F

10) Build, debug and press F8 key to resume. No message.

To fix it go to line 67 of file DbgCs1.h and change

#define BOARD_DEBUG_UART_INSTANCE 2

#define BOARD_DEBUG_UART_INSTANCE 1

Re-build-debug - hit F8 and the "Process started" message now appears.

I don't see how to upload a file.

Hi Christopher,

When in the "Reply" window, in the upper right hand corner is a grayed out (no idea why grayed out) "Use advanced editor" link. Click it and then you can click the "Attach" link in the lower right hand corner.

BTW: I have tried your steps with the Board and Processor option and both have the same results you have so I'm guessing this is a errata to the Wizard.

Zhang can you report this behavior?

Regards,

David

Thanks David,

Thanks for the quick response. Do you know how it should work? Is the UART choice supposed to set that #define statement?

Could you please give a short update on the problem. Will it be fixed?

I am running in the same issues and don't want to fix the #define after every PE generation cycle.

Thank you!

It is scheduled to be looked at and when I hear back I will update the post.
