OMAM3530 Pin Muxing Datasheet & TRM Discrepancies

Other Parts Discussed in Thread: OMAP3530

Hi,

I have two documents that detail the OMAP3530’s pin muxing: the Technical Reference Manual (SPRUF98D, October 2009), and the Data Sheet (SPRS507F, October 2009). The problem is that the two documents contradict each other. I’ve included a spreadsheet that shows the discrepancies between the two documents. This information was taken from tables 7-5, 7-6 and 7-7 of the Technical Reference Manual, and compared to table 2-4 of the Data Sheet. The attached spreadsheet is color-coded to show the nature of the discrepancies, and a legend for the color-coding is at the bottom of the attachment. Can you get someone to resolve these discrepancies or point us towards a document with the correct information?

Thanks,

Andrea Ramos

    FYI, there is a Rev E of the TRM.  The dssvenc signals (gpio_158 - 164) were corrected in the new revision of the TRM.  They should not be there.

    Please see Section 1.5.1 which shows the supported features/peripherals.  Most of the signals you mention that appear in the TRM but not the datasheet are unsupported peripherals.

    For hsusb2_tll your table is wrong as far as I can tell.
