Hello Prashant,

Can you telnet to the target? And issue the following: cat /proc/cmdline

And post it here?

In the meantime, you can verify the issue with:
https://www.raspberrypi.org/documentation/configuration/cmdline-txt.md

Hope this helps,
Zee

Dear Team,

I need to get the stdout data to serial console via uart1(serial1).

I given change in my cmdline.txt as: dwc_otg.lpm_enable=0 console=serial1,115200 consol=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait kgdboc=serial0,115200
and in config.txt as:

dtoverlay=pi3-disable-bt
dtparam=uart1=on
# Enable UART
enable_uart=1
dtoverlay=uart1,txd1_pin=32,rxd1_pin=33
core_freq=250
force_turbo=1

then also I'm not getting the serial output in my serial1.

Please help to resolve this issue.

Thanks & Regards.
