Hi,

 

I tried to switch on some LED during boot with script.bin. (connected to PH11).

Decompiled script.bin, changed several times PH11 to be an output with value 1 (pin 15 on GPIO3).

It works if I switch it on from Linux.

 

; Was the first I changed

lcd_used=0

lcdd11 = port:PH11<1><1><default><1>

 

; Whats this? Not used, or?

ms_used = 0
ms_d3 = port:PH11<5><default><default><default>

 

; Both changed

gpio_pin_19 = port:PH11<1><1><default><1>

pin_19 = port:PH11<1><1><default><1>

Compiled it again, copied it into /boot/script.bin, rebooted, nothing.

Its the last statement used? I didn't change ms_d3, but all other.

 

Using 3.4.105-lime2 with debian....

 

Any ideas? Is there a way to "debug" script.bin?

 

Thanks,

Jan

Hi Jan,

 

lcd_used=0, so the following code where you switch on the pin will be not executed. I think that this is not the right way. Leave lcd_used=0 and register your LED as LED device:

Try to add to script.fex following section (or modify existing) like this:

[leds_para]
leds_used = 1
leds_num = 1
leds_pin_1 = port:PH11<1><default><default><1>
leds_name_1 = "my:special:led"
leds_default_1 = 1
leds_trigger_1 = "default-on"

Thanks, but its only partial working.

 

On another port I defined a pullup resistor and this worked. But I can't set the direction to output on startup.

 

Is there a device tree configured, which overrides the script.bin?

(This would fit, because I cannot change the pullup/down-feature inside linux)
