Hi TI,

I have been able to integrate the TI provided tool for eye diagramming using Uboot but when I use TI SBL I faced issues when are mentioned in the ticket below:
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1553402/tda4vm-access-to-on-the-fly-eye-curve-diagramming-data

Question: Is the TI eye diagramming tool compatible with TI SBL? If not, what steps are nescessry to integate TI tool with SBL?

Hi Hasan,

I am checking internally whether the TI Eye Diagramming Tool is compatible with TI SBL and will update you.

Hi Hasan,

Integrating the tool into bootloaders was not the intended use of the tool. Therefore, we do not have steps to provide to perform what you are asking.

Two common methods that have been used to setup the system to use the tool:

Bypass bootloader code (i.e, through no boot, or do not pass a valid boot image). Use GELs / CMM scripts to setup PLLs and DDR. Load tool over JTAG as stand-alone image.
Boot device through bootloader. Stop bootloader after DDR init. Load tool over JTAG as stand-alone image.

Kevin

Hi Kevin,

Thanks for the info.

One more question: Is the perl script provided with the tool to convert the recorded uart logs to eye diagrams only supported with excel 32 bit? I am unable to run the script with excel 64 bit?

Looking forward to your response.

Best regards,
Hasan

Hi Kevin,

It will be great to have the above question about Excel 32/64 bit answered.

Hi Hasan,

I am not aware of any specific limitations due to different Excel versions, but I have never had issues.

Current version of Excel on my PC is Microsoft 365 Version 2506 Build 16 (64-bit), and it works fine.

Kevin

Also, did you try running the perl script on one of the example log .txt files that is included?

It may be an issue with the log file you have collected, so using the example files is a good way to check whether the issue is related to the log file, or something else.

Kevin
