Freescale Kinetis SDK FreeRTOS utility files missing

dankarm — Tue, 07 Jul 2015 17:30:38 GMT

Using the Freescale Kinetis Software Development Kit (Kinetis SDK 1.2.0), when attempting to display the information about the FreeRTOS tasks used by calling the "vTaskList()" function after enabling the "configUSE_TRACE_FACILITY" flag in "FreeRTOSConfig.h", compile errors are generated in "tasks.c" because "Utility.h" is not found. Related to that are missing functions: "Utility_strcat()", "Utility_chcat()", and "Utility_strcatNum32u()".

In comparing the Kinetis-supplied "tasks.c" to the latest "tasks.c" from the FreeRTOS web site, this appears to be due to Freescale modification to that file (by EST). It appears that the Kinetis SDK 1.2.0 is missing the "Utility.h" and "Utility.c" files for the FreeRTOS support.

I was able to make it work by implementing the missing functions as follows:

void Utility_strcat(uint8_t * dest, uint32_t bufSize, const unsigned char * src)

{

strncat((char *)dest, (const char *)src, bufSize);

}

void Utility_chcat(uint8_t * dest, uint32_t bufSize, unsigned char src)

{

char buf[2] = {src, 0};

strncat((char *)dest, buf, sizeof(buf));

}

void Utility_strcatNum32u(uint8_t * dest, uint32_t bufSize, uint32_t src)

{

char buf[10];

sprintf(buf, "%ld", src);

strncat((char *)dest, buf, sizeof(buf));

}

with the following example output results:

-> tasks

NAME STATE PRIORITY STACK TCB#

------------ ------- -------- ------- -----

CmdLine R 2 44 2

IDLE R 0 176 4

LED B 1 38 1

CDCproc B 3 28 3

Tmr Svc B 17 369 5

('R'=ready, 'B'=blocked, 'S'=suspended, 'D'=deleted)

Thanks for sharing Dan. I will report to the powers that be.

Hi Dan,

that FreeRTOS port is based on a universal port with/for Processor Expert (see Tutorial: FreeRTOS with the Kinetis SDK and Processor Expert | MCU on Eclipse ).

Somehow that utility module was not included with the SDK, so thanks for reporting.

You can find an updated port for the SDK (which includes a newer FreeRTOS v8.2.0) here, along with the utility module:

mcuoneclipse/Examples/KDS/FRDM-K64F120M/Lab_KSDK_FreeRTOS/Sources at master · ErichStyger/mcuoneclipse · GitHub

That port includes as well FreeRTOS+Trace from Percepio (Updated Percepio Tracealyzer and Trace Library to Version V2.7.0 | MCU on Eclipse ).

If I can find time, I will post an article about this in the near future.

I will work with the SDK engineering team that the next version will include that as well. Until then, you could use that port from above GitHub directory.

I hope this helps,

Erich
