Hi there,
I am using the OMAP 3530 CPU with board design similar to mistral evm board. The X-loader is fine, and at the u-boot time I get the I2c I/O error that looks like this:
Texas Instruments X-Loader 1.47 (Nov 9 2010 - 17:25:04)

after this, if I let the kernel boot, i see more error messages from TWL (as I understand this is audio driver).
