Team,

The base board of the TMDSEVM572X and the X15 are quite close but not identical.

I remember that I saw a list of the difference somewhere but can not find it again.
-Do we have a rough description of what the differences are?
As far as I recall it was just slight changes of PCB layout. I think that the BOM was the same. correct?

-In case you want to use the Linux SDK on the X15 what IO config (for IO timings) file need to be used?

Thanks,

Anthony,

Although the Beagle-X15 isn't officially supported, the necessary dtb files are included with the Processor SDK Linux binaries such that it should work.

The Beagle-X15 removes the current sense resistors that are on the TI EVM board. Looking at the dts files, I can see there's a difference in which GPIO pin is used to control the OE pin of the tpd12s015. The TI EVM uses gpio2_30 while the Beagle X15 Rev B1 and later use gpio6_28. I don't have the history on why that was changed in the Beagle-X15, though it is handled by the dts file.

The main change in the C1 version of the Beagle-X15 was moving to Silicon Rev 2.0.

Best regards,
Brad
