LPC54608 BACKLIGHT PWM

[enricobe]

Hi all,

I'm working on a custom project based on LPC54608 reference eva board.

I've got a question regarding PWM generation over SCT0_OUT5 (PIO3_31) signals: SDK's demo projects init this channel without starting the timer through SCTIMER_StartTimer(), and the IOMUX for that signal is not configured (FUNC2).

Trying to fix this missing points we lead anyway to a fixed '1' level at that pin.

Do you have any hints?

I've tested another board with IOMUX and SCT timer start and everything is working. I guess the eva board could be damaged at dc/dc converter (to be checked).
