Embedded development resources
Embedded Software Engineering 101 provides an excellent general introduction to embedded systems, making it particularly useful if you’re transitioning from general-purpose software development.
Bare metal embedded is a YouTube playlist that compiles a series of lectures I found particularly interesting. It walks you through the process of building a bare-metal program for ARM Cortex Mx systems, explaining each step, from writing a linker script to understanding memory layout, the vector table, the role of the startup script, and finally flashing and running the program on a board.
If you’re using Nordic Semiconductors board, or Zephyr RTOS in general, the free courses on Nordic Developer Academy provide an excellent introduction. They also provide courses on communication technologies such as BLE and WiFi, which are definitely worth checking out.
