Hi, all...
I am attempting to build a kernel for the AM3517 EVM directly from mainline (2.6.37 stable). All appears well, except that the Davinci EMAC clock failed to register. See end of message for my kernel log.
Used omap2plus_defconfig, with only one changed: enable CONFIG_TI_DAVINCI_EMAC (TI Davinci EMAC Support)
I also tried disabling CONFIG_OMAP_RESET_CLOCKS (Reset unused clocks during boot), to no avail.
Thanks in advance for your help.
Regards,
Peter
P.S. Why am I not using TI's pre-packaged release (2.6.32)? Trying to do a performance comparison with another ARM processor that is supported in 2.6.37.
