Using the above as a guide, and with a copy of the DaVinci datasheet, you should be able to get what you want working. | Using the above as a guide, and with a copy of the DaVinci datasheet, you should be able to get what you want working. | ||

Do this via U-Boot
Open davinci.c from the boards directory in U-BOOT.
The stuff regarding pinmux is in there. More specifically:
#define PINMUX0 0x01C40000
/* Enable UART0 MUX lines */
*(volatile unsigned int *)PINMUX4 |= 1;
/* Enable EMAC and AEMIF pins */
*(volatile unsigned int*) PINMUX0 = 0x80000C1F;
Using the above as a guide, and with a copy of the DaVinci datasheet, you should be able to get what you want working.
