TR 02:04 AM PCB Development: getting AUDIO_SYSCLK to expansion connector

I have an Industrial I/O board and need to get the AUDIO_SYSCLK signal out to an expansion board connector. Currently I am using signals from J701 to interface with my external codec and pin 26 appears to be free.
Before I start sold... Tom Riddle

This is definitely not a version of u-boot that we support. Which could explain all the ECC errors you get in the kernel when you try to read from nand. If this u-boot you are using is not configuring the ECC ... Jonathan Cormier

MW 12:26 PM Software Development: RE: Kernel panics on custom board: "No init found. Try passing init= option to kernel"

Is your custom board using a MityDSP-L138, or have you designed a custom board using the OMAP-L138 and not the module?
If you have done a custom carrier card and are still using a MityDSP-L138, then there are multiple things going on ... Michael Williamson

Turns out that the custom board doesn't even have a @factoryconfig@ command. The two boards appear to have different versions of U-Boot installed.

This line is very concerning. It appears you have erased or corrupted the modules factory config which is likely causing the kernel to think it has the wrong nand device.

Hi Jonathan,
Ok, good suggestion... thanks... the pinmux read
