Serial console not working with UART3 rock-3c

[ManavAChauhan]

Hi,

I executed the ./rbuild -o rk3568-fiq-debugger-uart3m0,rk3568-uart2-m0 rock-3c bullseye xfce command to enable fiq debugger on uart3 and enable the uart2 as a normal serial port. I can see both overlays are enabled in my rock-3c. but i don't see any ttyFIQ port inder dev/ folder and no logs on uart3 pins.
If i enable only fiq uart3 then it's working and i can see the logs on uart3 pins.
Please let me know how can i enable uart3 for debugging logs and uart2 as a normal serial port.

Can you send the bootlog generated by U-Boot. There might be some issue when applying the overlay.

Hi,

Please find attached the boot logs
dmesg_logs.txt

U-Boot log is not part of dmesg and can only be viewed with the serial port. We will test this issue.

Ok. Let me know once you complete the test for this issue.
