We only have U200 and U50, how to modify to support these boards ?

U200 should be easy by adding -board au200 when calling vivado in .RecoNIC/scripts/Makefile: vivado -mode batch -source build.tcl -tclargs -board=$(BOARD) -max_pkt_len 9600 -impl 1 -overwrite 1 -board_repo $(BOARD_REPO), where BOARD=au200.

U200/U250 has DDR, while U50 has HBM. The memory controller should be different. Thus, you need to port HBM's memory controller for it.

Feel free to re-open the issue if needed.

Hi, Guanwen,
For the HBM board (U280), can we start by building the shell without using the HBM?

Hi Zhaoyang,

To build U280 without HBM, you can simply remove ddr controller interface in open_nic_shell.sv, update ./scripts/Makefile for adding new board support and remove "dev_mem_ddr4_controller" in ./base_nics/open-nic-shell/src/utility/vivado_ip/vivado_ip.tcl. In this case, you won't be able to use any features related to the device memory.

You can start a new thread for this if you have further questions, as it's a new topic.

Thanks,
Henry
