RE: HOW TO - Connect the serial console - aivanise - 05-06-2022 I've bought a ch340 uart converter from pine shop, it looks exactly like the one on the picture. But when I put the yellow jumper on 3v3, i get nothing in dmesg, only when I put the jumper on 5V I get USB device recognized in dmesg and the ttyUSB port is there, but then,, of course, I don't get anything on it since it is on 5V This is on 5V # dmesg | tail -f [98293.116166] usb 3-1: new full-speed USB device number 3 using uhci_hcd [98293.304184] usb 3-1: New USB device found, idVendor=1a86, idProduct=7523, bcdDevice= 2.54 [98293.304187] usb 3-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0 [98293.304190] usb 3-1: Product: USB2.0-Serial [98293.307329] ch341 3-1:1.0: ch341-uart converter detected [98293.314267] usb 3-1: ch341-uart converter now attached to ttyUSB0 this is on 3V3 (...) nothing, nada, zilch any ideas? is my ch341 dead? My PC too old? RE: HOW TO - Connect the serial console - a9121431 - 05-08-2022 Hi all, Three weeks ago, the RockPro64 kit and serial connector arrived. I tried to run the Debian installer, I could see the console output and failed to enter anything. I connected the PIN 10 when the installer menu was shown, but the console simply did NOT accept any input. Any idea what went wrong ? Thank you, John RE: HOW TO - Connect the serial console - z3bra - 09-21-2022 (05-06-2022, 06:44 AM)aivanise Wrote: I've bought a ch340 uart converter from pine shop, it looks exactly like the one on the picture.

I bought one from the store last month, and I have the same issue. The converter's LED lights up red when I plug it in 3.3V, but dmesg/lsusb remain silent. Tried with Linux kernel versions 5.15.0 (ubuntu 22.04) and 5.15.8 (manually compiled). So far, I only get messages in dmesg output with 5V mode enabled.

This is what I did to change the baud rate on the Debian Installer:
