Thank you for your help. pwmchip0 and pwmchip1 2 files are there.
Weird thing is that after echo "pwm-test-P9.." and echo "pwm-test-P8...", though there are pwm-test-P9_14 and pwm-test-P8_13, and contents of the directores are same, only P8_13 does show result in oscilloscope but P9_14 does not show result.
