EPXA10 Development Revision
This errata sheet provides updated information about development ARM®-based family embedded processor programmable logic devices (PLDs). development contains EPXA10 development board. Most errata related development board. Identify revision number your Excaliburdevelopment before using this errata information, because been revised. Revised information given this document affects only revision Excalibur development kit.
identify revision number development kit, revision number development board contained must identified. Examine Altera® logo, which located lower-right corner board. revision number revision boards printed dark green left logo below connector. this errata sheet, revision information must XA10 Development Board Revision 2.1. Revision boards populated with EPXA10F1020C1 device. revised information given this document updates information following board features:
CONF_DONE U125 U126 daughter card connectors Connected nets functionality connectors Errata Excalibur ARM-based embedded processor device versions Excalibur cores
Information each errata includes assessment severity problem, which indicated grade from next problem description. grade anomaly likely affect only small proportion customer applications, then only under specific operational situations. Grade anomalies generally have work around with minimal impact customer application. grade anomaly could present challenge most applications. recommended contact Altera latest information.

CONF_DONE
Observation
CONF_DONE development board does reflect status EPXA10 CONF_DONE signal.
Cause
CONF_DONE connected INIT_DONE EPXA10 device.
Work Around
avoid confusion, relabel development board manually.
U125 U126 Daughter Card Connector
Observation
U125 U126 daughter card connector pin-out table earlier versions Excalibur EPXA10 Development Board User Guide incorrect.
Cause
following connections stated correctly versions earlier Excalibur EPXA10 Development Board User Guide. Table lists correct physical connection between connector U125 development board EPXA10. Table Connections Between EPXA10 Device U125 EPXA10 Device
U125 Daughter Card
Table lists correct physical connection between connector U126 development board EPXA10. Table Connections Between EPXA10 Device U126 EPXA10 Device

Work Around
Tables five development board connections listed, instead using versions earlier Excalibur EPXA10 Development Board User Guide. Alternatively, download version from
Connected Nets
Observation
Some pins U125 daughter card header change their signal level independently.
Cause
Table shows signal nets which connected development board. connections between daughter card header, U125, EPXA10 device right left correct. connections between nets right left false connections. Table Connected Signal Nets U125
False Connection

Observation
Communication ports corrupted does work when only slaves present.
Cause
pins Req1 Req2 have pull-up resistors.
Work Around
recover communication, following:

Connectors
Observation
labeling connectors development board incorrect.
Cause
labels reversed development board silkscreen, causing labels incorrect. actual connection connectors correct 3.3-V 32-bit universal cards.
Work Around:
Relabel connection necessary; refer EPXA10 Development Board Hardware Reference Manual correct usage connectors.
