unreadable characters on minicom window

[gurpartap]

Sir, I put ubuntu trusty image on Sd card in A20-micro-4gb board. I connected serial cable to uart0 connector which has 4 pins tx,rx,gnd,3.3v. But the log shown is strange.

  Minicom settings are 115200, 8N1.

Please confirm that debug interface is on uart0 or any other pins.

You don't get any input or it's distorted? At u-boot, kernel ...? Can you paste the output?
