# SLC Nand 128MB, 100K P/E cycles, normaly we test 5K P/E ¡ª¡ª 128MB * 5000
|
# src file size 5MB, totle test data 128MB * 5000, testcount = 128MB * 5000 / 5MB * 5(dirnum) = 20600

# 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;
