Hi,
my UART terminal is being flooded with USB debug messages as soon as I connect any cable on it:
[ 28.823118] xhci-hcd xhci-hcd.1.auto: irq 165, io mem 0x5b130000

is there anyway to disable it ? the terminal is unusuable while the messages are being printed.
my distro, Yocto - Gatesgarth (from code aurora):
Linux imx8qxpc0mek 5.10.9-1.0.0+g32513c25d8c7 #1 SMP PREEMPT Tue Mar 9 02:17:18 UTC 2021 aarch64 aarch64
aarch64 GNU/Linux
Thanks,

You can use "dmesg -n 1" command to disable all messages from the kernel (and its drivers) except panic messages to be appearing on the terminal.
Thanks for your support,
Regarding the messages, it looks like the usb OTG is not working correctly, I am not able to get any device enumerated. Can you check it ? I already checked 5.4.70 and 5.4.47 bsps. All the same
Regards,
Andre
