I get nothing from UART DEBUG. On my MacBook when I plug in the DB9 to USB Serial Adapter I see /dev/tty.usbserial.
screen /dev/tty.usbserial 115200
This works when connected to a different device I have.
When powering up or resetting I should see the bootloader logs, yes?
Also, what is the default (boot from SD) setting for S3?
I switched to my linux box and dmesg indicates
[485401.375378] usb 3-8: new full-speed USB device number 25 using xhci_hcd
[485401.503840] usb 3-8: New USB device found, idVendor=067b, idProduct=2303
[485401.503844] usb 3-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[485401.503846] usb 3-8: Product: USB-Serial Controller D
[485401.503848] usb 3-8: Manufacturer: Prolific Technology Inc.
[485401.504218] pl2303 3-8:1.0: pl2303 converter detected
[485401.504813] usb 3-8: pl2303 converter now attached to ttyUSB0
Still nothing when I use minicom or cutemon. Starting to think I have a bad cable. Will try your "test on PC" suggestion but need to round up the correct DB9 male/female converter..
Hi Rick
please check Linux Guide in Linux documentation
and User Guides on
SABRE|Automotive-Infotainment|i.MX6|NXP
Debug uart communication can be tested on PC with RS232 port.
Best regards
