Can rp2040 run code on a second processor?

The RP2040 contains two ARM Cortex-M0+ CPU cores; in this chapter, we look at how to run code on the second processor. The second processor is in a power-conserving sleep state by default; we’ll see how to wake it up and assign it work to process. Raspberry added two helpful features to the RP2040 for working with both CPU cores:

How does the rp2040 assign an interrupt handler?

Let’s look at how the RP2040 assigns an interrupt handler for each of these. When the RP2040 powers up, the IVT is located at address 0x00000000; however, the SDK’s power-up routines move it to SRAM by setting a number of hardware registers associated with the ARM Cortex-M0+’s interrupt configuration.

What is rp2040 assembly language?

In this chapter, we put that aside and look at a new Assembly Language syntax quite different from ARM’s. The RP2040 contains eight programmable I/O (PIO) processors that are programmed as state machines with their own Assembly Language instructions.
