Period and duty cycle look fine, so Tested-by: Geert Uytterhoeven <geert+renesas@glider.be> I had hoped to test PWM0, PWM3, and PWM4, too, as they are all available on test points, but I couldn't locate CP238, CP240, and CP241. The silk screen for CP239 points underneath the heatsink, so probably all four of them are obscured by the heatsink and/or switch board... Gr{oetje,eeting}s, Geert
