Hi,

Please post the output from the following commands in linux user space:

cat /sys/kernel/debug/omap_mux/spi0_sclk
cat /sys/kernel/debug/omap_mux/spi0_d0

Most probably there is some pinmux conflict with another init function from the board file.

Best regards,
Miroslav

paste pinmux snap.... You can verify pinmux conflict with pinmux utility provided by TI.

Best luck
