Adding comments from #1810 [now closed as it was redundant to the original issue here]. Additional info for what is required:
Grapefruit connects to our Ruby dev board and is important to unblock SW work for Cosmo. Context for the existence and purpose of Grapefruit is located in RFD 461. We are requesting software work to be completed to support board bringup and testing to unblock Cosmo SW work.
Features
Timing
schematic can be found in the latest grapefruit GH release: https://github.com/oxidecomputer/hardware-grapefruit/releases/
This should be considered a blocking issue for board bring-up, we'd like to be able to run some semblance of hubris and humility on the target hardawre day1 to facilitate hardware checkout by toggling pins, reading i2c etc.
