Release Notes
The following section contains information about deviations to the
description in this manual. Revisions to previous manuals are also
listed.
Caution:
This manual exclusively describes the board revision 1229.0
Revision:
PCB# 1229.0
Refer to the processor’s errata sheet provided by Freescale.
•
ColdFire integrated USB device does not work due to a processor
bug.
•
/RSTO does not follow /RSTI. During /RSTI active /RSTO is held
tristate by the processor resulting in a signal level depending on the
external connected components. /RSTO needs an external pull-up
resistor.
•
Bootstrapping option FBMODE is set to FlexBus address bus on
PCIAD pins. This is done by the pull-down resistor R11. Next
revision will have a pull-up resistor to initiate the PCI bus. PCI bus
cannot be used while FBMODE is initialized to 1.
•
ADC converter is not present on 1229.0. Footprint is not
compatible to the device.
•
Bootstrapping problems for the PHY 1 (U18) device. Reset input
must be connected to /RSTI instead of /RSTO.
