Hi, during change from 3.8 kernel to 4.14 I struggled with an issue regarding PWMSS accessed by PRU. On old kernel I load overlay am33xx_pwm to activate the PWMSS. I verified this with: devmem2 0x483000000 (base address of PWMSS0)
With 4.14 kernel I get 'bus error' when I execute same 'devmem2 0x483000000' Also PRU have no access to PWMSS. But loading the am33xx_pwm seems succesful, at least the sysfs folder is populated with pwm folders. How can the PRU gain access to PWMSS?
