Arm Musca boards (musca-a, musca-b1) — QEMU documentation

# Arm Musca boards (`musca-a`, `musca-b1`)

The Arm Musca development boards are a reference implementation of a system using the SSE-200 Subsystem for Embedded. They are dual Cortex-M33 systems.

QEMU provides models of the A and B1 variants of this board.

Unimplemented devices:

- SPI

- I2C

- I2S

- PWM

- QSPI

- Timer

- SCC

- GPIO

- eFlash

- MHU

- PVT

- SDIO

- CryptoCell

Note that (like the real hardware) the Musca-A machine is asymmetric: CPU 0 does not have the FPU or DSP extensions, but CPU 1 does. Also like the real hardware, the memory maps for the A and B1 variants differ significantly, so guest software must be built for the right variant.
