Here is a suggested support of 3 types of AMD Alveo boards: U55C, U280, U250. It is based on embedded meep_shell which includes QDMA based PCIe inteface, 2 kinds of supported DRAM: DDR and HBM, support of multi-MC (Memory Controllers) connection to HBM utilizing free NOC ports of edge tiles. Apart of this the contribution includes modified NOC-AXI4 bridge, 100GbE solution based on Ultrascale+ CMAC hard-macro+QSFP and AXI-DMA, BSCAN based small JTAG shell. Support of Alveo boards is provided as independent of Vivado versions. The last checked Vivado version is 2024.1. The bitstream built in different configurations and utilizing all above is Linux bootable.
