I was running the supplied binary on my omap-l137 eval board per the instruction:
- insmod dsplinkk.ko
- rm -f /dev/dsplink
- mknod /dev/dsplink c 230 0
My eval board (OMAP-L137) responded very slow. Note that mine run for 10 seconds versus the instruction shown as 1/4 seconds. What did I do differently?
