Other Parts Discussed in Thread: OMAP-L138

Hi,

Today I have downloaded OMAP-L138 WinCE SDK For OMAP-L138 from TI's website.

The version of the SDK that I have downloaded is 1.0.2.

While compiling the OSDesign the compiler throws an error that Audio and SDHC0 are mutually exclusive.

I had referred the Base Board schematics of Logic PD. But I don't see that the SD Slot using GP[0][11].

But in source code of the BSP the GPIO was set as output and set to high.

Why this pin was mutually exclusive between Audio and SD0 interface?

My actual version of the LogicPD Base board evm is 1013527 Rev 5 and SOM Revision is: 1014650 Rev.A

I have downloaded the latest schematics from LogicPD but I get only schematics for Rev 4 of the base board.

I wonder whether we can actually use the latest BSP with the EVM which is available with us now.

Thank You & Regards,

Hello GSR,

In newer version of EVM (baseboard 1016660 Rev A, SOM 1015517 Rev B) the SD slot is using GP0[11].

Since your board is an older version, it should not have the mutual exlcusion. You may enable both SDHC and audio by replacing the bsp_cfg.h file with the one from BSP_WINCE_ARM9_01_00_01. The file is also attached in this post.

Thanks,
