Rev 2 board with Rev 1 ID...

Sat Feb 09, 2013 6:08 pm

I've had an email from someone who has a Rev. 2 board - physically obvious with the mounting holes and by working out the BCM_GPIO 21->27 arrangement, however the revision in /proc/spuinfo is showing 0002.

(it also has 512MB of RAM)

This is causing some confusion!

Is there a way to fix it?

Perhaps use the amount of RAM as definitive? 0002 should be hardware revision 1.

I'm fairly sure there are Rev 1's with 512MB of RAM...

And I'm not sure how to read the RAM quantity ignoring the GPU split anyway...

But yes, 0002 is/should be Rev 1. raspi-config is as upset (memory split section) as wiringPi is on this Pi!

The board revision nunber is not reported correctly when using early firmware. Are you using the latest Raspbian image?

Well it's not me, just reporting it for someone who emailled, however oddly enough he may not be.

Looks like this has fixed it...

There shouldn't be, The Rev 2 predates 512MB. Only by a couple of weeks. I have a Rev2 'B' with 256 MB.
