Errors when checking memory bank index using "xbutil examine --report memory" command

[Heng-Zhou]

The XRT native API documentation says we can use xbutil examine --report memory command to check the memory bank index. But I always got errors.

First I was asked to use --device to specify device. This is easy to solve. So the command now becomes

xbutil examine --report memory -d 0000:3b:00.1

But when I run this command, the first problem I encountered is that there is no information related to memory bank index. Only platform name was returned:

-------------------------------------------------
[0000:3b:00.1] : xilinx_u280_gen3x16_xdma_base_1
-------------------------------------------------

I have no idea how to fix these errors and I want to get the memory bank index using xbutil examine --report memory command as the document suggests, especially those related to HBM. Can you please lend me a hand? Thank you.

I am using Alveo U280 accelerator card on Ubuntu 22.04. The XRT version is 2.15.228 (released on 2023-06-13).
