This is experimental, community-supported port for Cortex-M emulation as

provided by QEMU (http://qemu.org).

The purposes of this port are to enable:
|
|
|
|
|
|
|
|
|
|
1. Continuous integration
|
|
|
|
|
- run tests agains architecture-specific parts of code base
|
|
|
|
|
2. Experimentation
|
|
|
|
|
- simulation & prototyping of anything that has architecture-specific
|
|
|
|
|
code
|
|
|
|
|
- exploring instruction set in terms of optimising some part of
|
|
|
|
|
MicroPython or a module
|
|
|
|
|
3. Streamlined debugging
|
|
|
|
|
- no need for JTAG or even an MCU chip itself
|
|
|
|
|
- no need to use OpenOCD or anything else that might slow down the
|
|
|
|
|
process in terms of plugging things together, pressing buttons, etc.
|
|
|
|
|
|
|
|
|
|
This port will only work with with [GCC ARM Embedded](launchpad.net/gcc-arm-embedded)
|
|
|
|
|
toolchain and not with CodeSourcery toolchain. You will need to modify
|
|
|
|
|
`LDFLAGS` if you want to use CodeSourcery's version of `arm-none-eabi`.
|
|
|
|
|
The difference is that CodeSourcery needs `-T generic-m-hosted.ld` while
|
|
|
|
|
ARM's version requires `--specs=nano.specs --specs=rdimon.specs` to be
|
|
|
|
|
passed to the linker.
