GDI API specification

gashtaan — Sat, 06 Sep 2025 04:40:59 GMT

I'm trying to find some information about GDI API, i.e. how to create GDI plugin for CodeWarrior 11.1.

I made a BDM programmer based on ESP32 to program/debug the device over the WiFi, but it would be nice to add support for it to CodeWarrior. It reckon it should be doable as some layer to translate GDI commands to network requests, maybe using "GDI Generic" connection?

I've found out there should be something like "GDI API Documentation" in SDK that NXP doesn't shared it publicly. It doesn't seem I'm eligible to contact their support to request such SDK as I'm not an registered professional Is there a way how to obtain it?

@pgo Please help. NXP claims that no such SDK exists, but as I'm browsing through your USBDM code, especially GDI.h file, I see comments like:
//! 2.3.26 DiFeaturesT
//! 2.3.52 DiValueT

It seems you are referring to some specification. Where did you get that knowledge from?

The interface appears to be based on "Tasking GDI spec".
There is only one reference that I can find on the USBDM website:
https://usbdm.sourceforge.io/USBDM_V4.12/html/index.html
The link on that page is no longer active:
Tasking GDI Spec - http://www.tasking.com/resources/technologies/debuggers/gdikdi.shtml
I couldn't find any information on the www.tasking.com web site.
I suggest you approach the Tasking company as I no longer have the spec.

bye

@pgo Many thanks for the hint. I already noticed this reference to tasking.com, but I found out the page is already dead. I'll try to contact them.

Hi @gashtaan,

We do not have any GDI API specification. I apologize for any inconvenience this may cause.

I recommend following the information shared by @pgo.

Best Regards,

Pablo
