What is the problem?
I try to update the firmware of my SKR 1.4 trought rx/tx connection and usbmount/flash firmware.
serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)
octoprint.log (495.1 KB)
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible)
I can connect OP to my board and control it but I cant mount the sd card to make the firmware update.
OP > Version 1.4.0
Marlin 2.0 settings for a working RX/TX connection Between SKR V1.4 and PI4 with Octoprint.

#define SERIAL_PORT 0
