Pixhawk ARM issue

I’m using Pixhawk Flight controller , but I won’t arm , and fleshing yellow light ,
But I don’t know what should I do

I already told you what to do in the other tread

but its not working bro

how I fix it?
what should I do

It’s telling you right on the screen it’s a battery failsafe. Is the battery connected? Did you configure the battery monitor settings?

Don’t post a screen shot. Google “pixhawk power monitor” read the wiki and configure it.
