README

*Why this readme?: Becoz all the time I was getting wrong info about my processor when I used commands like lscpu and cat /proc/cpuinfo.

  • Official Response (Mongodb): Installation on 32bit system: Click here. TLDR: NO, its not at all recommended bcoz newer version are no longer developer for 32-bit architecture.

NOTE: Below output is from the Rasbian OS only (i.e., 32 bit os, and it was showing all informatino wrong about the processor i.e, arvl7 but my actual processor was Cortes-A72 Processor {Device Name: Raspberry-pi-4-model-b})

Check the problem stated here: Click here

NOTE: My raspberry process is 64-bi quad-core Cortex-A72 processor.

armv7l processor can only run 32 bit OS

Source: Click here, Source2: Click here

Is my running Linux kernel 32 bit or 64 bit?
