BCM20732S start up time is about 1S based on 1.1.0 SDK, and BCM20737S start up time is about 3.5S based on 2.1.0 SDK.
Solved! Go to Solution.

Are you using an EEPROM, or Serial Flash on your design? If EEPROM, the following link may be the contributing factor: Wake up time from sleep/deep sleep (continued)
That thread discusses a change to the I2C bus speed which impacts the rate at which the firmware gets downloaded from EEPROM into RAM during boot.

I means the boot time of BCM20732S and BCM20737S, we have similar application firmware which runs on BCM20732S and BCM20737S, and after the APPLICATION_INIT, in the hello_sensor_create thread, we will print welcome information, while the BCM20732S based on SDK 1.1.0 prints the welcome information in1s, while the BCM20737S based on SDK 2.1.0 prints the welcome information in 3.5s.

dianke02 do the two links provided above not help?? I feel like the second one should be very helpful in answering why there is a boot time difference.
