Figure 19. Resistors configuration
Table 16 describes the zero-ohm resistors configuration to select onboard flash memory or other board
components on the flash interface lines.
Port[pin] /
Signal
Resistor Resistor configuration Description
P3_0 R897 Connects FLEXSPI0_SS0 to
the flash chip select signal
(through resistor R470)
P3_1 R897 Connects FLEXSPI0_SS1 to
the flash chip select signal
(through resistor R469, which
is DNP by default)
Note: Both resistors, R470
and R469 should not be
installed simultaneously.
P3_7 R898 For flash clock signal
FLASH_RST_
B
[1]
R899 For flash reset
P3_6 R900
• Selection A (Pin 1-2) (default setting): Flash interface
line connects to onboard flash memory
• Selection B (Pin 2-3): Flash interface line connects to
flash daughter card connector
For flash data strobe signal
