Firmware Alpha 10 unable to start test

[Wabbalubbadubdub123]

After flashing systemcore alpha 10 firmware and updating all the devices' firmware to alpha in Phoenix Tuner, the motors cannot be controlled.
However, blinking in tuner still behaves normally.

A new trial but with systemcore firmware alpha 9, things are working fine. It appears to be the issue of the latest firmware alpha 10.

We also observed that alpha9 doesn't seem to be able to connect to new ds. If we force the new DS to connect to the IP 172.30.0.1, the log in DS says everything's good but FMS is bad, and only entering our team number(5515) will show only comm is good.

Anything <10 won’t work right with the DS.

Also note that Alpha/Beta 10 images are incompatible with WPILib versions prior to 2027.0.0-alpha-5, and CTRE has not released a Phoenix 6 version that is compatible with Alpha 10 images and WPILib alpha-5 (the image incompatibility is why Phoenix motor control does not work on alpha/beta 10 images).

From @bhall-ctre on Discord:

Full warning, while we may get something out sooner, I wouldn't count on anything being released until early June. Enough has changed between our 2026 release and WPILib that we essentially have to redo much of our work to cut anything, and we're still considering pushing out one final 2026 release before then.
