Functional Description

JTAG

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

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

Reset

Main Reset is send by Slave CPLD via X0, X1 Pins.

USB PHY hold ~0,6s after Main Reset or XMOD_G Reset or inv.RGPIO Bus Pin 0 (if active).

USB HUB hold ~0,25s after Main Reset or XMOD_G Reset or inv. RGPIO Bus Pin 0 (if active). Long delay is a BUGFIX: is currently need to start Linux before Reset is disabled.

I2C Reset is Main Reset or inv. RGPIO Bus Pin 2 (if active).

ETH Reset is Main Reset or inv. RGPIO Bus Pin 3 (if active).

Enable

FMC VADJ Enable is set from Slave CPLD via Saity Check (X6, X7).

SFP1 and SFP2 are always enabled.

Oscillator U45 is enabled

USB

USB Hub Device Operation Mode (USBH_MODEx Pins) are set to internal ROM configuration. Can be controlled by RGPIO Bus Pin 4 and 5.

ETH

PHY Address is 1.

Display Port

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_S sourced by S16.

SD

SD WP is forwarded to Slave CPLD.
