Diff between OMAP and XOMAP

Other Parts Discussed in Thread: OMAP-L138

Recently, I received a OMAP-L138 EvalKit, which is having XOMAP-L138 Processor. The document says, X mean experimental version. Please provide more info about this. Is there any possibilities existence of hardware anomaly? How check the hardware Rev of this chip?

    As you suggest the X stands for experimental, but practically it just means early silicon, i.e. silicon that is created before the ramp up of full production with full production validation. This could mean there are errata for it which are resolved in later silicon revisions, but in general there is nothing wrong with using the 'experimental' version (note for others, the equivalent for other TI processors would be TMX320).

    The revision should be in the printed part number on the top side of the package as described in section 1.2 of the silicon errata document, the full nomenclature for the part number is given in section 7.1.2 of the datasheet. If your top side marking has no letter (i.e. XOMAP-L138ZWT as opposed to XOMAP-L138AZWT) than it will be rev 1.0 silicon, and all errata in the document mentioned above will apply.
