Hi, I'm using SAME70-QMTECH board. defconfig file is attached.
In general additionally to standard NSH config I have added: CONFIG_EXAMPLES_PWM=y CONFIG_PWM=y CONFIG_SAMV7_PWM0=y CONFIG_SAMV7_PWM0_CH2=y and added to my board.h: #define GPIO_PWMC0_H2 GPIO_PWMC0_H2_1 /* PD_22 */ The sam_pwm.c is copied from same70-xplained. I have a logic analyzer connected to GND + PIOD PIN22. When I run "pwm -t 1" I observe that the signal goes from low to high then stays high approximately for 1 second and goes back to low.
