RTCS_Create Error

Jeff32 — Wed, 16 May 2012 21:29:44 GMT

I'm using MQX 3.8, IAR 6.30, and a K60 TWR-K60N512 and TWRSER. I'm trying to run the ipc_udp RTCS example but the call to RTCS_Create returns an error and causes the program to enter the idle task loop rather than start sending messages. Debugging shows that the value of error after the error = RTCS_Create(); call is 4406 (which may be the decimal representation of an error code 0x1136?). I haven't been able to find reference to either error code in the code or documentation.

This is the provided MQX code for cpu1 of the ipc_udp example and hasn't been modified except for updating \config\twrk60n512\user_config.h from #include "small_ram_config.h" to #include "maximum_config.h" since small_ram_config had MQX_USE_IPC defined as 0. I have rebuilt the MQX libraries since modifying user_config.

I don't know why this provided example code isn't working and have been stuck on this for a while now. Has anyone else encountered this or does anyone have any ideas?

Thanks,

Jeff

I found that error code 0x1136 = RTCS: Open queue failed. Does anyone know how to resolve this?

Hi Jeff,

Before calling RTCS_Create (), try to modify and test the value of the following variables:

     _RTCSPCB_init
     _RTCSPCB_grow
     _RTCSPCB_max
     _RTCS_msgpool_init
     _RTCS_msgpool_grow
     _RTCS_msgpool_max
     _RTCS_socket_part_init
     _RTCS_socket_part_grow
     _RTCS_socket_part_max

You can find more information about these settings in the document MQXRTCSUG.pdf.

Good luck

Thanks for the reply Tgomes. I checked the values of those variables just before RTCS_create() was called and tried modifying some of their values but still got the same error. Then I tried changing _RTCSQUEUE_base just to give it a shot. I changed it from 16 to 8 and it worked. I'm not sure exactly what effect this has but all I needed was _RTCSQUEUE_base = 8; before the RTCS_create call. Thanks for help!

Hi, i was with the same problem in a KSDK Processor expert project and I add the next configuration:

Select menu Project > Properties

Select C/C++ Build > Settings

Select Cross ARM C++ Linker > Libraries

Add new Libraries (-I)...

ksdk_platform_mqx

_rtcs

_mqx

_mqx_stdlib

Add new Library search path (-L)...

"${ProjDirPath}/Project_Settings/Linker_Files"

"${KSDK_PATH}/lib/ksdk_mqx_lib/kds/K64F12/Debug"

"${KSDK_PATH}/rtos/mqx/lib/frdmk64f.kds/debug/mqx"

"${KSDK_PATH}/rtos/mqx/lib/frdmk64f.kds/debug/mqx_stdlib"

"${KSDK_PATH}/middleware/tcpip/rtcs\lib/frdmk64f.kds/debug/rtcs"
