Hi All,
I compiled helloworld app in dpdk-19.11.1 stable version and tried to run .
The app is crashing with panic message.
Logs:

Below are my configs
1. Compiled app for 32 bit.
2. GCC version is 4.9
Created hugepages as below,
echo 1024 | sudo tee /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
sudo sysctl -w vm.nr_hugepages=1024
mkdir -p /mnt/huge_2mb
sudo mount -t hugetlbfs nodev /mnt/huge_2mb -o pagesize=2MB
Linux(debug)# cat /proc/meminfo | grep Huge
HugePages_Total: 1024
HugePages_Free: 1024
HugePages_Rsvd: 0
HugePages_Surp: 0

Thanks and Regards
