    For F281x we have never updated the ROM.  Version 1.

    The version and release date (month/year) are both embedded in the ROM itself.  The locations are documented in the boot ROM reference guide.  For the F281x, the document is www.ti.com/lit/spru095 section 2, page 11.

    We realize any change will cause many of our customers to update their code and/or retest/requalify.  For this reason, changes after TMS or Rev A are not an option for us.

    Up until now, no changes have been made after silicon goes to TMS.  For Piccolo, Rev A will have an update, and this has been documented in the errata.

    Changes are documented in the errata and the boot ROM guide.

    In the case of 281x the bug would be documented in the errata.  As I mentioned before changes after TMS or Rev A are not encouraged.

    In cases were the device is being sampled, the version in the ROM will be increased by 1 (0x001, 0x0002 etc) or a letter added and the date in the ROM will be changed appropriately.    In one case we had a minor change that was identified before the code went to silicon so the ROM version number has a letter (ie 0x0B01).  These are documented in the reference guide.
