hi~!
I have three boards.
1. EVM imx6q-sabresd. quad core 1GHz, DDR3 1GB 533MHz. kernel 4.9.xxx ga kernel
2. EVM xilinx zynq , dual core 866Mhz, DDR3 1GB 533MHz. kernel 4.4.....
3. custom design board imx6DL dual core 1GHz,DDR3 1GB 400MHz.kernel 4.9.xxx ga kernel
I ran the attached program and measured lap times.
condition. CPU Governor = performance, DVFS = disable, root=/dev/ram0
1. imx6q, avg. 96.. sec (evm sdcard image, )
2. zynq, avg. 75.. sec
3. imx6dl avg. 110.. sec
condition. CPU Governor = performance, DVFS = enable, root=/dev/ram0
1. imx6q, avg. 96.. sec
2. zynq, avg. 75.. sec
3. imx6dl. avg. 110.. sec
I think that Imx6 should have a shorter lap time than ZINQ.
I do not know why this results.
I made a lot of trial and error to reduce the lap time of imx6.
Now, I do not know what to do to reduce imx6's lap time.
I want to be helped on this matter.
Q1. How much is the lap time on your board??
Please run "test_cputest.o" on the attachment from the board and let us know the lab time.
Q2. If your board has a lap time of less than 80~70 sec, Help me with any special way to improve CPU performance.
There are three attachments. Attachments are source, executable and kernel config.
Please help me~~~!
