ok thanks, at the moment I'm happy with 4 inputs and 2 outputs... I just wanted to understand if I could midify the current system... but now I'm keeping alpinelinux because it works well in NAND

I'm using Alpine Linux installed on Nand Luckyfox Pico Max.. the command is correct but I can only control pins 54 and 55.. I have no idea where the problem is..

I did a lot of tests but the only pins to control a relay are only 55 and 54, only these work correctly.
do you know any other pins ?

hi, I can control two relays via gpio 55 and 54 from bash commands, they work fine. I want to use two more relays for a total of 4 but I can't find them. many pins give me this error: echo 68 > /sys/class/gpio/export -bash: echo: write error: Invalid argument only these two pins work: echo 55 > /sys...

thanks for your answer.
how can I do ?
I'm supposed to have SPI NAND FLASH (256MB pico max) but it seems like I've only taken up half the memory 100.7M?
ubi0:rootfs 100.7M 88.6M 12.1M 88% /

what am I missing?

ok perfect
A thousand thanks

Hi, I'm using Alpine Linux installed on Nand in Luckfox Pico Max.
from the terminal send command 'poweroff ' but the board does not turn off but restarts.
How can I turn off the tab from the command line?
thank you for your help

this leads to confusion... in this case on Luckfox pico pro-max is correct... why don't you do the same for pico plus?

Hi, these data were taken from the official LuckFox website and it appears to be a version with 512 DDR2 and 1GB of SPI Nand Flash.

I contacted Banggood support and they owe me answers to my questions.
