SabreAuto UART Configuration

cbrust — Mon, 26 Oct 2015 19:29:15 GMT

I'm trying to reconfigure our custom board based upon the SabreAuto (iMX6Q) to use a different UART for serial console for u-boot and Linux. I have been unable to locate any real instructions on how this can be accomplished but have derived a lot of it by reading the processor manuals and examining code. I have been unable to locate some of the definitions in the code even with exhaustive searching. Specifically, I cannot find the following definitions.

MX6_PAD_KEY_COL0__UART4_TX_DATA

MX6_PAD_KEY_ROW0__UART4_RX_DATA

Could someone point out where I can find these symbols and also some better instructions on how to reconfigure U-Boot/Linux to a different set of PADS.

Thanks,

I have exact the same issue.

I do not find where the above two constants are defined in the u-boot source code.

It looks like a miracle that it compiled fine.

Edit, Ok, according to the definition of MX6_PAD_DECL every thing is clear now.

There exists a definition for MX6_PAD_DECL(KEY_COL0__UART4_TX_DATA.... which is basically creating the constant i was looking for.
