Can we modify it to support U200 and U50 ? How to do it ? #13

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

zhguanw-amd commented 8 months ago

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?

zhguanw-amd commented 7 months ago

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
