RSL not blinking when deploying a blank python project?

[gerth2]

The last thing we tested tonight, which seems weird:

Code:

import wpilib

class MyRobot(wpilib.TimedRobot):
    def robotInit(self):
        pass

pyproject.toml

#
# Use this configuration file to control what RobotPy packages are installed
# on your SystemCore
#

[tool.robotpy]

# Version of robotpy this project depends on
robotpy_version = "2027.0.0a2"

# Which extra RobotPy components should be installed
# -> equivalent to `pip install robotpy[extra1, ...]
robotpy_extras = [
    # "all",
    # "apriltag",
    # "commands2",
    # "romi",
    # "sim",
    # "xrp",
]

# Other pip packages to install
requires = []

On alpha 4

Run robotpy deploy. Driver STation shows good code, click enable. RSL (plugged in, and yellow LED indicator onboard) do not blink, but DS shows "Teleop Enabled"

Very weird.

There's a solid chance our SystemCore is in a weird state. We're gonna try the following debug steps:

1. Deploy an empty java project to the RIO. see if that works and has a blinky RSL on enable
2. Re-image the SystemCore, and deploy a blank robotPy project - see if that fixes the issue.

Pending results of those, we may continue debug in place, or give up and send the SystemCore back to my bench. If I can reproduce with no robot and a small codebase, I could get VPN access if anyone wants to remote in to see what's going on.

I would upgrade to alpha 5.

After upgrading to alpha 5 - we did have it randomly happen once, but mostly gone. log file:

Here's a second log if it's helpful

Logs show this is on mrccomm. It does a 12.5 second check for the heartbeat file. But if it fails it still attempts to work. We should probably make it so it crash loops instead so it can recover.
