JTAGENB set carrier board CPLD into the chain for firmware update. For Update set DIP S4-3 to ON.

Connector J30 FMC JTAG is not used and looped back.

Power

connected to XMOD2 JTAG. Set DIP S4-3 to OFF for FMC access.

PJTAG (MIO29..26) is connected to JTAF Pinheader J30.

Power

FMC VADJ is 1.FMC VADJ is 1.8V if S5-4 is ON else 1.2V.

...

SC10 is controlled by DP_RX when SC11 is zero else high impedance state. DP_TX controlled by SC10 and DP_DE controlled by SC11.SC12 is controlled by DP_HPD.

CAN

CAN_TX soured by SC18.

SC19 sourced by CAN_RX.

CAN is not used_S sourced by S16.

SD

SD WP is forwarded to Slave CPLD.
