BCM2937 datasheet ??? RPi 3B+

Tue Sep 21, 2021 12:59 am

Without physically looking at the chip I can read only part of the designation -
how do I identify the actual variation of BCM processor ?
I am looking for datasheet and I specifically need all GPIO registers memory assignment for my specific hardware.
Thanks

Do you mean 2837?

Note most info can be found in the documents link at the bottom of the raspberrypi.org web site:

Unless specified otherwise my response is based on the latest and fully updated RPiOS Buster w/ Desktop OS.
