CORTEX_M4_0: Error connecting to the target: Frequency is out of range.

Other Parts Discussed in Thread: CCSTUDIO, CC3200

Hi! This is my very first day with the TI EKS-LM4F232.

What does "CORTEX_M4_0: Error connecting to the target: Frequency is out of range." mean and how do I overcome this problem.

1) USB plugged in. 2) I believe the drivers are properly installed.

I'm trying to do Lab2 blinky light.

Evaluation kit borrowed from co-worker on vacation. Does some setting or switch on the board needs to be set back to default?

Ross,

I have seen that error in CCSv5.2 when there has been an issue with installing the drivers for the onboard ICDI jtag emulator. I was able to resolve by:

going to device manager
looking for Stellaris ICDI entries (I believe there are 3 of them)
right click and select update driver
point it to <your ccs install dir>\ccsv5\ccs_base\emulation\drivers\stellaris
It should find and install the correct driver
repeat for the other 2

That resolved the issue for me.

Regards,

John

Thank you John!

"In-Circuit Debug Interface" had an exclamation point next to it before updating driver, now it does not.

Program will run and "blinky light" responds to run and pause on CCStudio.

Thanks for your help. I would have taken quite a while(forever) to figure that out.

Hi,

Just for reference for others in the future, check the section 6 of the wiki page below. It contains some known issues regarding the CCS and Stellaris connectivity.

Hi John,

I have this same problem of Frequency out of range error. I went to device manager and tried to find the Stellaris ICDI entries but it seems they are not listed.

I did a fresh install for all the software that came with my EKS-LM4F232 following the Read Me First and Quick Start pdf files with no luck. My computer seems to not be recognizing the board. If I try to use LM Flash utility a message indicating no device could be found shows up. Code composer was working fine at the time of first purchase and installation but not now.

Hello Christian,

Does the device manager show unknown USB device? A snapshot of the device manager may be useful.

If it shows unknown USB device, then install the ICDI drivers from TIVA web site.

I was going through the same problem. My Tiva Launchpad was getting not detected and I couldn't see its entry in device manager. I think Stellaris driver got corrupted. After a fresh installation of the Code Composer Studio, it got solved.

Hi Amit

The three ICDI drivers aren't listed in other devices(device manager) although the stellaris icdi drivers are present in ccsv6->ccs_base->emulation->stellaris....

I use a cc3200 launchpad and can't upload my code because of the frequency out of range error.

Thanks,

Shubhankar
