Errata List

1Overview

This document describes the known errata and limitations of the Whitefin Development System. In all

cases, if an errata has a work-around, it is applied to the system before shipped to customers.

The board assembly revision (denoted with a 700 number) is updated every time a new problem or system

upgrade is found and systems have been shipped. Pre-production revs are “X1, X2, X3”... and so on. Once

in production, valid assembly revs are “A, B, C”... and so on. If your current board revision is rev “B’”,

then it has all rev “B” fixes along with all the r ev A, as well as all the previous pre-production fixes. A rev

“B” board would not have any of the rev “C” fixes .

Regarding the published schematics, the schematic history section found on sheet #2 of the schematics also

denotes which errata have been incorporate into the schematic. If no history is present, then no errata has

yet been incorporated into the schematic. In such cases, the errata should be applied to the published

schem atics to determine the corre ct wiring of the Whitefin system (i.e. after the changes are applied).

Errata are classified into three categories: correctable (CE), uncorrectable (UE), and enhancement requests

(ER). The last two categories are not corrected initially, but may be rolled into poss ible future revisions of

the system (if any). Table 1 includes all corrected CE for applicable pre/production systems. Also included

are corrected UE and ER for appl icable revisions that incorporated them. Schem Rev denotes which

revision of the schematic includes these corrections. Table 2 includes all UE and ER that have not been

incorporated in any revision to date.

R321 and R318 are used to allow SC457

sense circuit to operate without a processor
