BOOT BeagleBone via SPI0 - missing SourceCode and Documentation for STARTERWARE platform.lib

Klaus Liebschner

Hey Community,

I want to boot my BeagleBone Board via SPI0 on the Expansion header. I am using the AM335X_StarterWare_02_00_00_07. As the BBB does not feature the SPI as a example, I am using the mcspiFlash.c and the mcSPI.c from the evmAM335x folder structure in my recompiled \beaglebone\platform.lib. However, the functions McSPIPinMuxSetup() and McSPI0CSPinMuxSetup() are not included there and also there is no source code availabe in the Starterware package and also the Starterware User Guide doesn't identify the initialization steps I need to perform in exchange of these functions.

So I am a little bit stuck on how to proceed with doing a proper initialization. I would really appreciate your help. Klaus

hi,

You can refer the McSPI configurations for EVM platform. That will give you some pointer to proceed.

Hi,

in my post I mentioned, that I am using the library (platform.lib) of the EVM and not of the BeagleBone! However, the Source Code of the EVM platform.lib is not available in the Starterware package, so that I can find out the configuration differences between the EVM and the Beaglebone....

The EVM platform source is available at \\StarterWare\platform\evmAM335x.

Which release are you using?

Hi Baskaran,

thanks for the reply. I am using AM335X_StarterWare_02_00_00_07. It seems, as if I got confused with the different mcspi.c files available from:

...ti\AM335X_StarterWare_02_00_00_07\drivers\mcspi.c

and

...ti\AM335X_StarterWare_02_00_00_07\platform\evmAM335x\mcspi.c

Thanks for directing me to the right folder :-)
