As mentioned in previous dpdkthreads, i tried after changing the hugepage size to 1024 as well.
http://dpdk.org/ml/archives/dev/2014-November/007770.html
http://dpdk.org/ml/archives/users/2015-November/000066.html
echo 512 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
echo 1024 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
Tried setting the hugepage through ./tools/setup.sh (1024,4096...) as well. but facing the same error.
Could somebody help how to resolve this issue?
Thanks,
Raja
