- What I did
Updated S6000 CPLD driver to recover if the mux is hung during i2c operation
- How I did it
When i2c read or write fails, the mux is reset using GPIO 10 pin and the operation is tried again.
- How to verify it
Simulated the mux reset and i2c operations. The hung scenario cannot be created in a normal setup. However the code was modified in a way to try mux reset even for successful reads to check if there are any impacts due to reset. The mux reset doesn't cause any issues or have side effects.
