Install cross-compiler for Raspberry Pi 400 on Ubuntu VM running on Virtualbox in Windows

Job ID: 33070522

Budget: ₹1,500 – ₹12,500 INR

I have a Raspbeery Pi 400 running Raspian Buster image.

I also have Virtual running on Windows, which runs Ubuntu VM.

I also have a cross-compiler running on Ubuntu for Rapsberry Pi 4. But it can run simple programs like Hello World.

I need to build a platform where I can do real hardware development (that uses GPIOs, I2C, SPI, timers, ISR) on the Pi400. Libraries of Pi400 and cross-compile environment need to sink. Remote debugging.

I have some links and material that details the process, but something is missing. Maybe the proper structure, maybe something else. So, I need a clean environment to run and debug.
