McSPI with REV C

Hi,

First of all, thank you all for the thread
http://groups.google.com/group/beagleboard/browse_thread/thread/42988f0e14db0f01/90cfddb68a827347?#90cfddb68a827347

I followed it and successfully made bidirectional SPI work for BB.
However, I have following issues:

1. It works fine for Rev B board, but USB host port is disabled in
Rev. C board. Is there a pinmux conf. conflict between Rev B and C?

2. Is there a simple way to enable McSPI on Rev C board? There was
discussion going in the past to configure the pinmux through kernel
and keep u-boot untouched.

Thanks in advance,
Kunal

There is a difference in the Rev C and Rev B pin assignments on the expansion connector. This is documented in the System Reference Manual.

I have a rev A, I really need to get a rev C and use that for SPI stuff :slight_smile:

B7 and earlier VS. Rev C. It is documented in the Rev C3 System Reference Manual.
