The T2 card card has a DMB II connector located at the rear of the card, on the opposite side of the I/O bracket. It serves as a maintenance port for developer access to the following ports:
- UART to RFSoC
- This UART operates at a baud rate configured within the Zynq® UltraScale+™ RFSoC design, and can be used for software debugging of RFSoC PS applications as required.
- JTAG to RFSoC
- This JTAG chain to the RFSoC can be used for communication with the Vivado® Design Suite during development for programming and debug.
- UART to SC
- This UART operates at 115 kBd and can be used for querying the SC for system-level information during development.
- SWIO to SC
- This port can be used to program the SC if the in-band SC firmware update mechanism is not implemented within the RFSoC.
