Error connecting to the target CC3200 launchpad

Patrick LORBER said:

I have now CC3200SDK_1.0.0 (previous version when I received CC3200)

Try make a new CCS workspace for CC3200 SDK 1.0.0 and follow the CC3200 Getting Started Guide for CC3200 SDK 1.0.0.

It didn't solve the problem. I still can't connect to CC3200 with Uniflash:

Uniflash debug console:

What could be the problem with the COMP port settings ? Below printscreen of the settings:

Hi,

    Have you tried the Out of Box Demo using your smartphone, did it work?

    Try another USB cable and also try to make it work at another PC.

Hi,

I have tried the Out of Box Demo when I got the board. It did work. I also loaded wlanstation example with CCS and sketches with Energia. No problem. But now it seems impossible to connect the target (Signal ACK failed at final step of debugging).

Uniflash Error message is:

 FATAL: Error connecting to the device. Please check your COM port settings. Error code: -3

[19:27:43] INFO: > Executing Operation: Disconnect

[19:27:43] Operation GetVersion returned.

What could be the problem with the COMP port settings ?

Can you confirm the baud rate (921600 bps) ? Do I have to change other Com port settings ? What is error code -3 ?

Patrick

No solution ?

I am having the same problem unfortunately... Also using Energia.

In fact it has happened to me twice now (2 different boards).  The board will work for the first few attempts to program it, then it suddenly will stop...

I will be trying the boards on another computer soon, but if that doesn't work I am out of luck for my project, it sucks.

If you find a fix, let me know though!

Hi Kyle and Patrick,

     There are several posts here whereas the CC3200 Launchpad became defective or initially was defective for whatever reasons. TI engineer offered to replace those boards.

      I have been using my CC3200 Launchpad Rev 3.2 for months now and it is still okay. I just cut the power off whenever I am going to remove or place jumpers on the board. This is to prevent static discharge. I don't have static discharge preventing setup so I do this.

      There is a issue using Uniflash when there is a serial console using the same COM port as your CC3200 Launchpad. I have observed this many times and the solution is to close that serial console and Uniflash, then open just Uniflash, then power cycle your CC3200 Launchpad. There are several posts here discussing about this issue.

Hi Kel and Kyle,

I tried to just open Uniflash after closing all applications using the same Com port and powercycing CC3200. It didn't help. Definitely I can't connect to the LP with CCS or Uniflash (or Energia), but I can use FT_Prog: scan and parse or apply CC3200_LP3_Dual. Maybe a TI engineer could propose another solution ? I hesitate to buy a new board if the same problem can come back (as it seems to be the case for many people in this forum). I spent too many hours on this problem !

Patrick -

I have had a similar this issue in the past with two different CC3200 boards. It hadn't happened for a few weeks, but then, it reared its ugly head again last week.  This last time, after stopping/restarting CCS, power-cycling the 3200, yadda, the problem persisted.  

I disconnected the 3200, rebooted the PC, re-launched CCS, reconnected the 3200 and the problem was resolved.

Might make sense, if there is some sort of intermittent issue with the CC3200 COM port driver.  I have only "resolved the issue" one time in this manner, so who knows, but you might try rebooting your PC if you haven't already tried that.

Hi Jim,

I have also tried to connect/disconnect CC3200 or reboot PC or change PCs but it did'nt change anything. Seems to be hopeless !

Patrick 

Patrick,

This isn't really a solution, but I was forced to try programming my board with a different computer.  So far, it works without error after you install the drivers.  Thats not to say it will not simply stop working in the near future, as they have done in the past... but luckily for my useage I had the code ready to go, I just needed to program the board once.

I tried uninstalling the drivers and reinstalling, uninstalling just about everything and reinstalling, even restoring my computer to an older version before I ever started using the board, but nothing worked.  Not to discourage you, other people got it working again, but I sadly was never able to.

Perhaps try another computer if you have access to one, that is the best advice I have after being frustrated with this reading ACK error for far too long.

Kyle

Hi Kyle,

I have tried with another computer. Same problem with error ACK signal failed when I try to use Uniflash This is exactly wher I am: I can't connect the board with Uniflash (but I can connect it with FT_Prog).

Patrick

Patrick -

When you execute the Get Version option in UniFlash and get the "INFO: --- please restart the device ---" prompt on the Uniflash Debug Console, are you pressing the reset button on the CC3200?  If you don't press reset when prompted by UniFlash, you'll get the following sequence of output in the Uniflash Debug Console:

Hi Jim,

Of course I press the reset button when asked to.

Patrick

I transfer the problem to TI support as adviced by TI rep on chat support.

Can you let us know if you find a solution please? I am sure other people would like to know in the future as well.

Hi Patrick,

Regarding this board, may we contact you at the email address you provided in your E2E profile?

Hi Raghavendra,

Sure you can contact me at the address in my E2E profile.

Waiting for your email.

I tried to solve the problem by asking ASKTEXAS but they replied:

I am facing the same issue outlined here.

Out of the Box Demo worked for 2-hours, and after that I am not able to connect to it. I was told to try and reflash, but Uniflash does not connect to it.

The Board Version is Rev 3.2 

Please help. The Jumper SOP2 is connected, P58-Vcc are disconnected. The comport is properly configured.

Any help from TI here? Is there a fix for this? I'm currently having the same issue (and I've had it several times in the past). However, this time things seem really locked up. The posts on the forum regarding this issue go back as far as last November. Really losing confidence...

Oh, the hours wasted... hours... days, even. [dramatic effect]

Dear Patrick,

During the flash download time, did you already opened any serial terminal, like Tera Term etc.? If so, close Tera term and then try to debug. It might Run. 

As the same COM port is used for downloading code and also for serial monitor, it might clash. So, Error might happen because of this. Try and let me know.
