XDS100V1 Target connection error

Karuna Mudliyar

Other Parts Discussed in Thread: UNIFLASH, TMS320F28335, TPS62400

Dear all,

Greetings...!!!

The very first time i got new XDS100v1 USB emulator with Delfino F28335 control card, I made the "LED blinking" code run.
This code was in Flash memory. So whenever the emulator is powered up. It will run the same code by default -
LED 3 (GPIO 34) on control card would be blinking .

Then I use to "Launch selected Configurations " and "Connect Target" and do some other programming.

Recently I tried to perform Processor-in-Loop test - Matlab Simulation. There I run some Matlab code
for SCI communication (to effect the processor-in-loop test).

I think from there onwards i am not able to connect to my Target

Also, when it is powered up - that default code wont run (LED 3 wont blink instead all the three LED's glow continuously)

error : C28xx: Error connecting to the target: (Error -1041 @ 0x0) The emulator reported an error.
Confirm emulator configuration and connections, reset the emulator, and retry the operation. (Release 5.0.429.0)

When I performed "Test Connection" , the report was

HI Karuna, (Good to know that you too are from MIT)

Can you check with the voltage levels on the docking station esp. towards FTDI chip? Also please check with your target configuration (try changing the emulator description from XDS100 v1 to XDS100 v2)

Regards,

Gautam

Dear Gautham,

Thanks for your quick reply.

I have checked the voltage levels around FTDI and other part of the Docking Station. The 5V points were 4.7 V and 3V points were 3 / 3.3.

I changed the emulator description but still the error persists.

Here, when trying to connect through ccsV5 the target connect failure error is:

C28xx: Error connecting to the target: (Error -1015 @ 0x0) Device is not responding to the request. Device may be locked, or the emulator connection may be unreliable. Unlock the device if possible, and power-cycle the board. If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.872.0)

Even I used "Mprog - Multi Device EEPROM Programmer V 3.5" and programmed FT2232D.

Kind Regards

Hi,

Ohk, can you make sure that you're device is not locked by making use of Uniflash. It has unlocking feature, so use it and do revert.

Secondly, on the hardware side, do check if the controller is getting overheated or not.

Regards,

Gautam

Dear Gautham,

I tried making use of Uniflash to erase, program,unlock. Every time i do these operations, it tries to connect to target and fail.

It throws out the error.

[11:34:17] FATAL >> C28xx: Error connecting to the target: (Error -1015 @ 0x0) Device is not responding to the request. Device may be locked, or the emulator connection may be unreliable. Unlock the device if possible (e.g. use wait in reset mode, and power-cycle the board). If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.232.0)

Secondly, I checked that on the Hardware.

On Control card, near to IC U2, just below 3 LED's, found bit more hot compared to other place on the control card.

Hi,

Please check whether the IC has not been short circuited. Check the input and the output voltage levels of the IC and compare with its ideal values listed in the datasheet.

Regards,

Gautam

0 Karuna Mudliyar over 12 years ago in reply to Gautam Iyer

Intellectual 510 points

Dear Gautham,

I didn't found any short circuit.

But the voltage across capacitor C38 (22uF) is 0.22V where in schematic it is 1.8V.

SImilarly, with capacitor C29, it is 0.22V, where it should be 1.8V.

Does problem with control card? It is just 2 Months old.

Kind Regards

0 Gautam Iyer over 12 years ago in reply to Karuna Mudliyar

Guru 192875 points

Karuna, the age of the board never comes into picture. The voltage levels are one of the most important aspects of the board. So please check for the same and replace the faulty component.

Regards,

Gautam.

0 Karuna Mudliyar over 12 years ago in reply to Gautam Iyer

Intellectual 510 points

Dear Gautham,

In control card, the voltage across C29, and C38 should be 1.8V, where I am getting 0.2 V. I think I am not

getting 1.8V supply.

If you will be working on same device, can u tell me what voltage u are getting, that would be much more helpful. As it is difficult to believe that two capacitors get damaged.

0 Gautam Iyer over 12 years ago in reply to Karuna Mudliyar

Guru 192875 points

Karuna, currently I'm on tour; so I won't be able to verify the above. But as I've already mentioned 1.8V at the specific point is a must.

Gautam

Dear Gautham,

I will try to repair the hardware and revert u back...

Thanks and kind Regards

Sure, do let me know.

Dear Gautham,

It's a good news, the problem got solved, the target got connected.

I changed the above marked capacitor C29 and C38, which were for 1.8V supply, it got working.

So, the problem was that the capacitor was damaged, and by replacing them, i could get 1.8V and the target got connected.

Many thanks for your support.

Kind Regards

Hello;
I am working with the TMS320F28335 and I have the same Problem (the same Error message).
I suppose that one of the component was damaged.
Since am new with DSPs, Idon't know where repectively how to do necessary measurements. I'll be very grateful for any help.

Hello, haithem fkaier

In order to make necessary measurement you should have the schematic for that, you can find it here.

For TMS320F28335 control card, the important voltages, 5V, 3V/3.3V, 1.8V, across the respective capacitor, can be checked. If, any short-circuited capacitor found, need to be replaced.

Hello,

I have measured the voltage across the capacitors but i didn't get the optimal values (with c28, c29 c37 c38...) is it possible that all of these capacitors got damaged??!! I have also tried to replace c28 with a new capacitr, but the voltage level is always les than the optimal!!!
Help please...

.... I have got :

1,3V instead o 1,8V

0,08V instead of 3,3V

and 5V has been successful measured.....

0 Karuna Mudliyar over 12 years ago in reply to haithem fkaier

Intellectual 510 points

Hello,

0.08 V instead of 3.3 V is unavoidable. U need to troubleshoot the control card.

As per the schematic, U2 - TPS62400 is the IC responsible for generating 3.3 V and 1.8 V supply. I think u may not be getting that voltage.

The capacitor of interest is C37 and C38, check weather those are functioning.

Hello;

I have measured the voltage upon C37 (0,08V) and C38 (1,29V)!!! But i have remarqued that upon r6 r7 r21, i have no voltage....

Hey everyone.

What is the solution for the above problem? Is it a hardware or a software fault?

Thanks and Kind Regards,
