8 Revision history
8.1 Revision 1
Table 8-1. Xplain revision 1 – known issues.
8.2 Revision 2
8.3 Revision 3
Issue
Speaker is noisy during programming and
debugging of the ATxmega128A1 when
using JTAG.
AT90USB1287 cannot connect to FLIP
programming software to reprogram the
AT90USB1287 application section of the
flash.

Different revisions of the Xplain kit is released, these revisions are not fully identical it
can therefore be relevant to identify the board used.
Revision 1 of the Xplain kit can be identified by not having a bar-code sticker on the
back side.
Revision 2 of the Xplain kit can be identified by a bar-code sticker on the back side
with the following product ID: A09-0560/2.
Table 8-2. Difference between Xplain revision 1 and revision 2.
Revision 3 of the Xplain kit can be identified by a bar-code sticker on the back side
with the following product ID: A09-0560/3.
Table 8-3. Difference between Xplain revision 2 and revision 3.
Difference
Dataflash changed to
45DB642D-CNU
AT90USB1287 bootloader
R305 removed
Two jumpers added –
default placed on the J101
and J102.
Difference
Series resistors on SDRAM
lines removed
Shunt resistor (R105) added
Audio amplifier is default off
(R300 is pulling down the
SD line of the U300).
Cause
Problem due to cross-talk contaminating
the audio amplifier input.
No bootloader programmed in the
AT90USB1287
Comment
The 45DB642D-CNU is replacing the 45DB041D-SU.
Bootloader is entered by shorting pin 1 and 2 on the J200.
To eliminate noise on speaker during JTAG programming
and debugging of the ATxmega128A1.
For convenience of the end-user.
Comment
Not required – and therefore removed.
This is a zero ohm resistor that enables measurement of the
ATxmega128A1 current consumption.
Reduce power consumption and reduce faint noise from
speaker.
Solution
Use the PDI interface or remove resistor
R305.
Upgrade to the AT90USB1287 with the
latest firmware using an external
programming tool such as the JTAG ICE
mkII.
