Errata
5.1
The SPI lines available on the LCD connector J22 have been swapped.
Current implementation (wrong):
Pin 37 = SPI0_NPCS3
Pin 38 = SPI0_MISO
Pin 39 = SPI0_MOSI
Pin 40 = SPI0_SPCK
Correct implementation:
Pin 37 = SPI0_SPCK
Pin 38 = SPI0_MOSI
Pin 39 = SPI0_MISO
Pin 40 = SPI0_NPCS3
To date, there is no impact because no LCD screen available on the market uses the SPI bus on this connector, in
particular the PDA Inc. TM430x and TM700x product series recommended by Atmel.
A potential problem exists only if the future "Xplained Pro" series LCD extensions are used because these
extensions could require the SPI bus on this LCD connector.
Also, for customers or third parties planning to develop their own extensions using a connection to J22, we
strongly recommend following the correct implementation so as to guarantee a future consistency and
compatibility with all Atmel tools.
Workaround:
1.
Unsolder and remove resistors R96, R97, R101
and R103 located here:
2.
Solder isolated pieces of wire as follows.
Resin coated wires were used below.
Make sure not to create any short-circuits
between the wires and the other components.
