FMC Connector JTAG Bypass
When an FPGA mezzanine card (FMC) is attached to J5, it is automatically added to the JTAG
chain through electronically controlled single-pole single-throw (SPST) switch U27. The
SPST switch is normally closed and transitions to an open state when an FMC is attached.
Switch U27 adds an attached FMC to the JTAG chain as determined by the
FMC_LPC_PRSNT_M2C_B signal. The attached FMC card must implement a TDI-to-TDO
connection using a device or bypass jumper to ensure that the JTAG chain connects to the
U1 XCZU7EV MPSoC.
PS M.2 SATA Connector
[
, callout 32]
The M.2 SATA interface is provided for SATA SSD access using the PS-side bank 505 GTR
transceiver.
shows M.2 connector U170.
The socket 2 SATA adapter pinout with key M is shown in
. SATA-A data connection
is used for TX and SATA-B for RX. The M.2 connector U170 is a type 2242 (active component
section 22 mm wide with overall length 42 mm form factor) used on socket 2.
