I have followed this guide for Firefly SDK Buildroot and I am unable to get the shell on uart2 or fiq-debugger port.

I have checked multiple blogs, tickets, and forums, and edited .dts and .dtsi to:

Disable fiq-debugger and use uart2 as shell
Disable uart2 and enable fiq-debugger (default file mode)
Route fiq-debugger to uart 0x00 by editing serial ID and other configs to use uart2 (ttyS2)

…but I failed to get shell access.

I am a beginner in this, so I apologize in advance as I feel there might be a small issue I am unable to identify.

Here are the relevant files/content:
