Hello everyone~
If I set printk("hello world"); in my project (main.c), I wanna to know … how to see this serial console through usb TTL?
About TTL , I found this pin map (https://github.com/96boards/documentation/blob/master/IoTEdition/Carbon/AdditionalDocs/Images/HardwareUserManual/Carbon_Pinout.png?raw=true) and use the UART1_TX and the UART1_RX and 1 GND (In the upper left corner) to connect my USB TTL. And input screen /dev/tty.XXXX 115200 on my linux computer. But … it doesn’t seem to work .
