Why I did it [E1031] fix pca9548 initializes failed occasionally in stress test. When failure happened, ismt i2c bus hang up and need power cycle to recover it. How I did it Add 0.5s delay between setuping and configuring pca9548 i2c mux. How to verify it Reboot stress test at least 100 times without failure.
