→Exporting generated source file
To update the default pin mux configuration with your changes just overwrite the <code>board/dave/naon/pinmux.h</code> file inside the U-Boot source tree with the generated one.
Please also note that, inside pinmux.h, user should change:
<cpp>
#define MUX_EVM() \
MUX_VAL(PINCNTL1, (IEN | IPU | FCN1 )) /* SD1_CLK */\
MUX_VAL(PINCNTL2, (IEN | IPU | FCN1 )) /* SD1_CMD_MUX0 */\
MUX_VAL(PINCNTL3, (IEN | IPU | FCN1 )) /* SD1_DAT[0] */\
</cpp>
into
<cpp>
#define MUX_NAON() \
MUX_VAL(PINCNTL1, (IEN | IPU | FCN1 )) /* SD1_CLK */\
MUX_VAL(PINCNTL2, (IEN | IPU | FCN1 )) /* SD1_CMD_MUX0 */\
MUX_VAL(PINCNTL3, (IEN | IPU | FCN1 )) /* SD1_DAT[0] */\
</cpp>
