And use it in all ports. The ports are unchanged, except esp8266 which now just returns None from this function instead of the time elapsed (to match other ports), and qemu-arm which gains this function. Signed-off-by: Damien George <damien@micropython.org> |

README.md
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:
- Continuous integration
- run tests against architecture-specific parts of code base
- Experimentation
- simulation & prototyping of anything that has architecture-specific code
- exploring instruction set in terms of optimising some part of MicroPython or a module
- 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 the [GNU ARM Embedded Toolchain](
https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads
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.
To build and run image with builtin testsuite:
make -f Makefile.test test
