Task Mutex Example on TM4C123GH6PM

Other Parts Discussed in Thread: TM4C123GH6PM, EK-TM4C123GXL, SYSBIOS

Dear Champs,

My customer is under developing sensor fusion on Tiva TM4C123GH6PM.

They would like to run this fusion on RTOS, so they try to import SYS/BIOS example code
(Task Mutex Example) for practice.

They found there are some error when the device select as TM4C123GH6PM.

the error code as below.

====error code start

ti.catalog.arm.cortexm4.tiva.ce.Boot: line 66: assertion failure: A_mustNotUseEnhancedClockMode: This device does not support the Enhanced Clock Mode.

xdc.runtime.Error.raise: terminating execution

====error code end

But it works when the device change from TM4C123GH6PM to LM4F120H5QR.

as i know, the TM4C123GH6PM is same as LM4F120H5QR, but why the example code works on LM4F120H5QR, fail on TM4C123GH6PM.

please help to check the SYS/BIOS example code and System Analyzer works on TM4C123GH6PM (EK-TM4C123GXL launchpad) or not?

Thanks!

Do you have the following line in your .cfg for the failure case?

var TIRTOS = xdc.useModule('ti.tirtos.TIRTOS');

There was a misnaming issue that the TIRTOS modules works-around for you.

Sorry, I forgot to mention that you'll need to include TI-RTOS and un-select SYS/BIOS.

Please note that TI-RTOS includes the SYS/BIOS kernel and here is the version it includes:

Dear Todd,

I just import the SYS/BIOS mutex example code for LM4F120H5QR, and did not modify any program. it works.

but import the SYS/BIOS mutex example code for TM4C123GH6PM, and also did not modify any program. it does not work.

it make me confuse, why the example code works on LM4F120H5QR, fail on TM4C123GH6PM device selection. as i know, these two MCU were the same.

and i also check the cfg file.

there are only following line inside.

var BIOS = xdc.useModule('ti.sysbios.BIOS');

but when i change SYS/BIOS to TIRTOS and also add "var TIRTOS = xdc.useModule('ti.tirtos.TIRTOS');" in cfg file. the example code works on TM4C123GH6PM.

my question is, why the SYS/BIOS example code works on LM4F120H5QR, but fail on TM4C123GH6PM device.

Thanks!

Daniel,

xdctools_3_25_00_48 was too restrictive on the naming. TI-RTOS 1.10.00.23 put in a work-around. The problem was resolved in xdctools_3_25_1_65.

Hello, dear ToddMullanix.

I have the similar problem with Tiva C micro-controller.

So where may I download this xdctools_3_25_00_48?

Best regards,

Alex

Alex,

XDCtools, SYS/BIOS, TI-RTOS, etc. can be downloaded from here:
