TMS320F28055: Programming Issue

Hello,

Can you please re-attach the "Programming Connector" image? It appears to be too small to read.

Here is a helpful link in the meantime: https://software-dl.ti.com/ccs/esd/documents/ccs_debugging_jtag_connectivity_issues.html#invalid-data-read-back Could you also check for the items that it lists?

Best Regards,

Marlyn

Hi Sudip,

Everything looks okay in the schematics you have shared. Can you please attach the full report you get after running the 'Test Connection'? Please also ensure that everything is properly soldered and there are no loose connections.

Best Regards,

Marlyn

Hi Marlyn, 

1> Every connection is properly soldered and no loose connection present.

2> the error message as below:-

This error is generated by TI's USCIF driver or utilities.

The value is '-233' (0xffffff17).
The title is 'SC_ERR_PATH_BROKEN'.

The explanation is:
The JTAG IR and DR scan-paths cannot circulate bits, they may be broken.
An attempt to scan the JTAG scan-path has failed.
The target's JTAG scan-path appears to be broken
with a stuck-at-ones or stuck-at-zero fault.

Hi Marlyn,

FYI, The programming Settings as below:-

hi Hi Marlyn, FYI, I observed:-

According to datasheet 2.2k to 10K can make pull up at reset point, controller pin No.8. But i observed that even 470E not able to give 3.2V voltage. i think it is erratic. till now i am not able to solve the problem. waiting for your reply.

Hi Sudip,

The content you provided showed 'XDS2XX', this is different from XDS110, what debug probe are you using the XDS110 or the XDS200? 

Best Regards,

Marlyn

XDS2XX

Hi Sudip,

Thank you for confirming. Can you please go through this debug guide (https://www.ti.com/lit/spracf0 ) and let me know what step in specific fails for you? This is a resource we provide to narrow down the issue. 

Best Regards,

Marlyn

hi Marlyn, 

if no programmer is connected XRSn pin state like as:

I didn't find the cause.  help me please. 

-sudip

Hi Sudip,

Do you have the watchdog enabled in your program? 

Best Regards,

Marlyn

Hi, Marlyn,

no. it is new board. from start, nothing programmed to this chip. 

-sudip

Hi Sudip,

Okay, could you please let me know the status of the boot mode pins?

If possible, please put the device in Emulation Boot and then Wait boot mode, reset the connection under each mode.

Best Regards,

Marlyn

Hi Marlyn,

Now scan succeeded.  The status msg as below.

after uploading i am getting the below. error. 

what to do?

-sudip

Hi Marlyn,

I am also getting the below message.

sudip

Hi Sudip,

Glad the target configuration test connection now works!

Here is a link that talks about what data verification errors are and possible causes/solutions: https://software-dl.ti.com/ccs/esd/documents/troubleshooting-data_verification_errors.html 

As a first form of debug, can you please try loading a C2000Ware example? 

For example: C:\ti\c2000\C2000Ware_version\device_support\f2805x\examples\c28\timed_led_blink

If this example loads okay on your hardware then we will know there is something about how you've setup your program and we can continue the debug.

Best Regards,

Marlyn

Hi Marlyn,

I am getting the below error when start debugging...

-sudip

Hi Sudip,

Thank you for trying to load the example. Could you please read the password locations to make sure that the device is unlocked?

Best Regards,

Marlyn

hi Marlyn,

Thanks for your reply.

1. can you provide me info to read the password please?. 

2. I am observing RST pin state is low. due to this not uploading program? because when trying to upload i am getting the below message.

-best regards-

sudip

hi Marlyn, 

Thank you for your support.  The board is programming now. One issue. after removing JTAG, power disconnect and reconnect the board is not running.

can you please say why board is not running itself. 

-sudip

Hi Sudip,

Glad to hear it is programming now. If you don't mind me asking, what was the issue? It could help others on here with similar issues.

Are you flashing the program onto the device or were you only programming into RAM?

Best Regards,

Marlyn

Hi Marlyn, 

Our issue was in Hardware. We mixed up VDD and VDDIO. like below:

We segregate and programing ok. but after reset/power off/on program is not running. please help. what to do. now it running  in Emulation mode. what is the settings option to run stand alone mode.

-sudip

In order for the device to boot up and execute content from Flash please put the device in 'GetMode' by configuring the boot mode pins in the way shown in the table below:

Best Regards,

Marlyn

Hi Marlyn, Thanks for support.  nothing improve. my sequence as below:-

1> TRST HI, board power up

2> connect JTAG and program Timed led blinking example with Emulation. LED blinking.

3> board power off., remove JTAG

4> TRST=0, GPIO34=TDO = hi by 1.5K pull up at each pin

5> power up.

6> No led blinking program running

Hi Sudip,

Really glad to hear that! Hope you have a great rest of your day!

Hi Marlyn,

I need to implement TIRTOS in TMS320F28055. is there any example available?

best regards-

sudip

Hi Sudip,

Please create a new question on the forum so we can route this to right expert. Someone else should be able to help you setup TIRTOS within your project.

Best Regards,

Marlyn

Okkk.....Marlyn,....Thanks
