Hardware revision history and known issues
5.1
Identifying product ID and revision
The revision and product identifier of Xplained Pro boards can be found in two ways, through Atmel Studio or
by looking at the sticker on the bottom side of the PCB.
By connecting a Xplained Pro MCU board to a computer with Atmel Studio running, an information window will
pop up. The first 6 digits of the serial number, which is listed under kit details, contain the product identifier and
revision. Information about connected Xplained Pro extension boards will also appear in the Atmel Kits window.
The same information can be found on the sticker on the bottom side of the PCB. Most kits will print the
identifier and revision in plain text as
A09-nnnn\rr
where
nnnn
is the identifier and
rr
is the revision. Boards with
limited space have a sticker with only a QR-code which contains a serial number string.
The serial number string has the following format:
"nnnnrrssssssssss"
n = product identifier
r = revision
s = serial number
The kit identifier for SAM4N Xplained Pro is 1967.
5.2
Revision 2
Revision 2 of SAM4N Xplained Pro is the initial released version.
Known issues:
●
In backup mode, the ERASE pin will only work with a power toggle of the SAM4N. This however can't be
done by the embedded debugger because there is no switch to control the power to the target. So in cases
where e.g. an application is in backup mode and the user needs access in order to program/debug it is
necessary to do a manual erase procedure.
Workaround:
●
Please connect ERASE test point on the bottom side of the board to VCC (3.3V) e.g. pin 4 on the
PWR header. Remove power from the board and reconnect again. The device should be erased by
this procedure and it is possible to program/debug via the embedded debugger.
