2.2.27 LED Indicators
Table 4 describes the LED indicators on the main board. See Figure 6 for their locations.
SW9 FPGA RESET
Load FPGA configuration:
DOT = reset not asserted
NO-DOT = reset asserted (initiate configuration load)
SW10 nVDD_FLT
State of the
PXA27x nVCC_FAULT
pin:
DOT = not asserted
NO-DOT = asserted
SW11 nBATT_FLT
State of the
PXA27x nBATT_FAULT
pin:
DOT = not asserted
NO-DOT = asserted
