Identification of A0/A1 firmware on BCM20732S (SIP not SoC)

[MiTo_1583836]

I am testing the BCM20732S and I am wondering how can I identify if the firmware running is a A1 or A0 just by looking at the documentation.

I am not able to program an application with SDK2.x on the BCM20732S, so this means to me that I have a A0 firmware. I am not able to get any other confirmation looking at the documentation. The part number on the datasheet of the BCM20732S does not reflect the information.

Last point, if I dig into the SDK2.0.1 I do see in the changelog.txt file a branch that is created for BCM20732A1, BCM20736A1 and BCM20737A1 SoCs. This means we can have a BCM20732A1 SoC as well.

The question is: how can I identify if the BCM20732S (SIP) is burnt with the A0 or A1 ROM? How can we order a BCM20732S personalized with A1 instead of A0?

Thanks for clarification!

Note that there are no 20732S units in the mass market that are loaded with A1 firmware.

SDK 1.1 will only work with A0 firmware. If you cannot program using SDK 2.0, but SDK 1.1 works, it's A0 firmware.

Firmware revs are not identified within the part number for each device.

A 20732SA1 could technically exist, but it does not within the mass market.  There are several customers out there with A1 20732 silicon, but it's not supported in the broadmarket.

Ok thanks for the clarification.
