I need to control the backlight of LCD both with BL_ON (SODIMM 71) and PWM_A (SODIMM 59) pins.
In the bootloader I can use
setconfig ss to set
In this way, pin BL_ON works as expected.
On the other side, I can’t find any way to configure PWM_A and so I supposed the bootloader leaves this pin configured as an input. But it doesn’t seem so, ad it seems that the bootloader drives PWM_A (SODIMM 59) LOW.
Could you confirm this?
If this is the case, is it possible to add a new
ss parameter to setup PWM_A polarity?
This is not ok for me, since I need an “active high” PWM_A.
Is it safe if I overwrite GPIO configuration of this pin through setconfig
enter code here gpio bootloader command.
I’m worried about a conflict while driving this pin.
