Boot code

[Emilio]

I've got the PinePhone not the Pro, and haven't looked into the uboot details, but if you post the file or a link to it I'll have a go. I last looked at uboot configs in detail back in the openmoko days, but it looks like the concepts haven't changed much.

Thanks. I inserted de SD card in my laptop and enter de fat partition and copied
The boot to my desktop. I will copy it here in my android smartphone and paste it here.

# After modifying, run "ppp-uboot-mkscr" to re-generate the U-Boot boot script.

# This is the description of the GPIO lines used in this boot script:
#
# GPIO #105 is GPIO3_B1, or RK3399 ball C27, which controls the vibrator motor
# GPIO #154 is GPIO4_D2, or RK3399 ball AH3, which controls the red part of the multicolor LED
# GPIO #157 is GPIO4_D5, or RK3399 ball AJ3, which controls the green part of the multicolor LED
# GPIO #158 is GPIO4_D6, or RK3399 ball AG4, which controls the blue part of the multicolor LED

_-----
The gpios are clear. First you hear the sound of motor and inmedistely there's a red led and then
The sound of motor stops and the led become green. Of course if the "if" statements are ok. And
It is these if statements the I would like to understand. I Imagine that
Are variables containing values given by the ROM boot loader
