# example  ��
# 	count for script command:
#		SLC Nand 128MB, 100K P/E cycles, normaly we test 5K P/E ���� 128MB * 5000
#       src file size 5MB, totle test data 128MB * 5000, testcount = 128MB * 5000 / 5MB * 5(dirnum) = 20600
#   command:
#		sudo flash_stress_test.sh 5 20000
#	available space need:
#		src file size: 5MB
#		des file size: 5MB * dirnum = 25MB
#       log file size: 189B(log item size) * 20000 = 3691KB
#			    total: about 34MB
#   result analyze:
#		success:
#			1. shell progress stop;
#			2. print "-------copy and check success------------"
#		fail:
#			1. shell progress stop;
#			2. any printing with "error" tag
