[ 0.028386] CPU: Testing write buffer coherency: ok [ 0.032493] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000 [ 0.037108] hw perfevents: enabled with ARMv7 Cortex-A15 PMU driver, 7 counters available [ 0.043763] Setting up static identity map for 0x80464628 - 0x8046465c The uboot version which I used is from git://arago-project.org/git/projects/u-boot-keystone.git with tag DEV.MCSDK-2013-01.10, I also tried other tags, but seems no different effect. Could you give some advice about smp problem? Thanks in advance! Regards, Xiao
