Serial console in Linux - Orange Pi 2G-IOT

arturgomes

Hi,

Someone was able to use serial console in any linux distibution ? I already tried with many softwares like minicom, putty, screen, and the exactly baudrate 921600 and i just can't do it, it seems like the baudrate is wrong, but it is not.



Any Help ?

Maybe you need replace your usb to ttl.
I recommend usb to ttl of ch340/341.

So, i tried all this tree, and the problem is exactly the ch340, only CP2102 works!

It might be a defective dongle or you broke the cable.
Once I had a messed up cable on my Prolific dongle and it did the same. It was spitting out a bunch of garbage into terminal while connected to a wireless router I was trying to repair. Accidentally I moved the cable, and gibberish became normal text.
So, don't throw that dongle in the garbage, check the cable first.

I fully agree to you, same problem, same solution - thanks  fo posting this!
After trying USB  → UART adapter based on PL2303 and CH340 chip I only got rubbish in minicom.
Now I bought my 3. adapter based on CP2102 and it works flawless simply by plugging!
