Cross-Platform development

64-bit ARM machine code install cross compiler

QEMU

In cross-platform development, it’s easier to validate your code on an emulator first. You can use QEMU to test your code first before validating them on a real rpi3.

Deploy to real Rpi3

To prepare a bootable image for rpi3, you have to prepare at least the following stuff.

  • Firmware for GPU.

  • Kernel image.(kernel8.img)

Interact with Rpi3

  • kernel8.img , and put it into your boot partition. It’s identical to the one in the provided bootable image.

  • Plug in the UART to USB converter to your host machine, and open it through a serial console such as screen or putty with the correct baud rate.

  • Connect TX, RX, GND to the corresponding pins on rpi3, and turn on your rpi3.
