Dear
The CPU is dm8127. I test the speed of SD card write,I use 'time dd if=/dev/zero of=/dev/mmcblk0p1 bs=10240k count=1', log is as follow
~# time dd if=/dev/zero of=/dev/mmcblk0p1 bs=10240k count=1
1+0 records in
1+0 records out
real 0m 2.88s
user 0m 0.00s
sys 0m 0.23s
~# time dd if=/dev/zero of=/dev/mmcblk0p1 bs=10240k count=1
1+0 records in
1+0 records out
real 0m 5.66s
user 0m 0.00s
sys 0m 0.21s
CPU utilization 5%
MEM utilization 30%
The app don't run, the speed of the second test is slower, how to solve the problem
