Hi,
Thank you for reaching out. We're currently investigating this issue with AMD. We'll keep you updated.
from aws-fpga.
I hope this is the right place to post here, as I am expericing a similar problem:
Right now I'm working to put a MicroBlaze core with Vivado IP Integrator flow, however, I can't connect to the MicroBlaze Debug Module (MDM) when I deployed in on an EC2 F1 instance.
My design is as following:
design files: aws_mb_example.zip
I have followed #507, which mentioned to use "EXTERNAL HIDDEN" for BSCAN in MDM:
However, it seems failed to identify MDM, as when I connect it with XSCT, I got the following:
Top left is the SSH session of EC2 F1, which was running hw_server
and sudo fpga-start-virtual-jtag -P 10201 -S 0
Bottom left is the Vivado tcl shell, connected to the Virtual JTAG on F1
Bottom right is the XSCT, also connected to the Virtual JTAG on F1
The commands are run in this order: SSH > Vivado > XSCT
The targets command in XSCT gives 8-digit numbers only, but supposedly it should gives something like "MicroBlaze Debug Module".
May I ask if there is any problem with my design with a MicroBlaze? Is there an alternative method to connect to MDM, or is there an example design for MicroBlaze that worked with AWS EC2?
Thank you.

I imagine the first use case is using HDK flow and the second is the HLx flow. In both cases we need to make sure the debug_hub and MDM is connected properly.
Doing a first pass with 2021.2 with HLx flow with MDM/MicroBlaze similar to the testcase, I noticed that the connections to MDM were not correct. Can the post opt of both designs be open and can the following connections be verified(first snap shot)? If you can either post the DCPs or snapshots of the post opt connection like below (note no connects make sense for the below and the debug icon is for an ILA test I was doing).
Below make sure the debug bridge connections go to the shell (second snapshot).

In response to your inquiry, I confirm that for my case (first one), the mdm1 in the CL is connected to the boundary scan MUX locate in the STATIC_SH logic, per attached snapshot
