Hello Igor, thanks for the reply. Could you please share "/etc/modules" content and your dts if they're different from the standard build? Do you use any additional overlay file? -

with battery attached. Mine reboots also when I issue poweroff command. Without battery it shuts down regularly. -

Hi, did you try o attach a LiPo Battery to a Lime2 with latest uboot 2020.04 and kernel 5.4 and see if it shuts down correctly or it reboots? -
Hello all, If i detach battery all works ok. With attached battery system reboots instead of shutting down. Anyone experiencing this issue again with 5.4.21 kernel? Is there a workaround to solve it, maybe in u-boot or somewhere else? Armbian 20.05.0-trunk built from source Thank you

Need help in understanding a i2c configuration effect
sgufa replied to Peter Heß's topic in Allwinner A20
its "de" in DT. you can comment/remove &de { status = "okay"; }; in dt so the i2c hdmi adapter will not be initialized or you can use aliases to define i2c buses like aliases { i2c0 = &i2c0; i2c1 = &i2c1; i2c2 = &i2c2; i2c3 = &i2c3; }; so the i2c hdmi adapter will be named i2c-4 -
Hi all, as in title, gpio not work on latest Lime2 5.59 built from source using mainline 4.14.70 kernel and debian stretch. I can export correctly the gpios in sysfs but i cant get the right value. They always remain the same value. I've tried both pulled up and internal pulled up (active low) gpios with the same result. Also gpio buttons defined in dtc do not work. Any idea?
