5.4.3 Service Boot
The LPC3250 bootloader starts by reading the SERVICE_N (GPI_01) input when deciding from which
source to boot. If SERVICE_N is low a service boot is performed, which means that it will load code
from UART5.
On the QVGA Base Board, GPI_01 is connected to the P2.10 button. Holding down the P2.10 button
while resetting the board will force it into service boot.
There are four jumpers on the QVGA Base Board related to the USB serial channel, connected to
UART #5 on the LPC3250. See Figure 19 for details about where the jumpers are located. Make sure
the 'Service Boot' jumpers are open.
