Hi, I have a ROCK 5B+ with an emmc on board, therefore I cannot remove the emmc module.

The [document](https://docs.radxa.com/en/rock5/lowlevel-development/bootloader_spi_flash?method=external) only shows how to flash for the rock 5B(not for 5B+>)

This guide explains how to flash images using rkdevtools on Windows , and also includes a short terminal-based guide for flashing via SPI .

Flashing via Rockchip Dev Tools
