JTAG pod flat cable connector J36 (2 mm 2x7 shrouded/keyed), which
requires:
Note: In this mode, the FT4232 device (U20) UART functionality continues
to be available.
Set boot mode SW1 for JTAG as indicated in the "Mode Switch SW1
Configuration Option Settings" table in Versal Device Configuration.
On the 3-pin JTAG MUX, enable header J37 to inhibit the JTAG MUX.
Move the 2-pin jumper to be installed on pins 1-2 for high-z mode. See
Default Jumper and Switch Settings for defaults and Board Component
Location for location.
2-pole DIP SW3[1:2] setting does not matter as the MUX is
inhibited/turned off.
Power-cycle the VEK280 board or press the power-on reset pushbutton
(SW2). SW2 is near the USB-C JTAG port J369 in the figure in Board
Component Location).
OSPI
This boot mode is supported onboard and is wired to the XCVE2802 U1 bank 500
PMC_MIO[0:12] pins. The octal SPI controller can access two devices using several
different methods. See the Flash Memory Controllers section of the Versal Adaptive
SoC Technical Reference Manual (AM011) for more information. To boot from OSPI:
1. Store a valid XCVE2802 adaptive SoC boot image file in the OSPI.
2. Set boot mode SW1 for OSPI as indicated in the "Mode Switch SW1
Configuration Option Settings" table in Versal Device Configuration.
3. Power-cycle the VEK280 board or press the POR pushbutton SW2. SW2 is near
the USB-C JTAG port J369 in the figure in Board Component Location.
SD1_3.0
To boot from a SD card installed in microSD card socket J302:
1. Store a valid XCVE2802 device boot image file on a microSD card. Plug the SD
card into the VEK280 evaluation board SD socket J302 connected to the
XCVE2802 U1 bank 501 MIO SD interface.
2. Set boot MODE SW1 for SD1_3.0 as indicated in the table in Versal Device
Configuration.
3. Power-cycle the VEK280 board or press the POR pushbutton SW2. SW2 is near
the USB-C JTAG port J369 in the figure in Board Component Location.
