This ability was lost after 88ccb09.

Some notes from testing this locally:

I don't have to set LUNA_PLATFORM at all which is great. In order to get this running I had to add a few things (some of which exist in #237), like adding "apollo_fpga @ git+https://github.com/greatscottgadgets/apollo.git", to pyproject.toml and the following modifications to /ci-scripts/build.sh:

pip install "cynthion @ git+https://github.com/greatscottgadgets/cynthion/#subdirectory=cynthion/python/"
pip install "amaranth-stdio @ git+https://github.com/amaranth-lang/amaranth-stdio@4a14bb17"

The following are all back-to-back runs of interactive-test.py from within a python venv using oss-cad-suite-linux-x64-20240327 and both the "debug/alt" and "control host" ports (left side ports) connected on an r0.4 board. Connecting only debug/alt always results in the (bitstream provides data past the device's SRAM array / ffffffff) error.

This looks to me like an Apollo firmware bug affecting JTAG on r0.4.

mossmann · 2024-04-03T18:16:44Z

I was able to reproduce this on r0.3. I could run blinky.py successfully until updating Apollo firmware. After updating Apollo firmware I got:
