2.15.1 Erratum 36: D19 LED is placed on bottom side instead of top side
2.15.1.1 Description
MCU-Link LED D19, which indicates if USBSIO bridge traffic is present, is placed on
the bottom side of the board. Verifying the LED status while working on the board in
inconvenient as the LED is placed on the bottom side.
2.15.1.2 Impact
Difficultly in verifying the LED status.
2.15.1.3 Workaround
None.
2.15.1.4 Fix plan
D19 LED will be moved to the top side of the board in next board revision.
2.15.2 Erratum 46: JP57 jumper is DNP
2.15.2.1 Description
Jumper JP57, which disables the USB-to-SPI bridge between MCU-Link and the target
MCU, is not populated on the board. By default, the USB-to-SPI bridge is enabled and
the target MCU SPI connection is used with MCU-Link. To use the target MCU SPI
connection with other peripherals, such as SPI NOR flash memory, JP57 jumper must be
populated and shorted.
2.15.2.2 Impact
The target MCU cannot connect to the SPI NOR flash memory.
