zephyr: Initial Zephyr RTOS port, MicroPython part.

#
zephyr/Makefile: Update comments to the current state of affairs.
2016-11-04 12:13:49 -04:00
# This is the main Makefile, which uses MicroPython build system,
# but Zephyr arch-specific toolchain and target-specific flags.
# This Makefile builds MicroPython as a library, and then calls
# recursively Makefile.zephyr to build complete application binary
# using Zephyr build system.
zephyr: Initial Zephyr RTOS port, MicroPython part.
2016-07-22 13:18:17 -04:00
#
zephyr: Move "minimal" configuration building to a separate wrapper script. Minimal config can be now build with: ./make-minimal BOARD=... This is required because of Makefile.exports magic, which in its turn depends on PROJ_CONF to be set correctly at the beginning of Makefile parsing at all times. Instead of adding more and more workarounds for that, it's better to just move minimal support to a separate wrapper. Also, remove Zephyr 1.5 era cruft from Makefile, and add support for Zephyr's "run" target which supercedes older "qemu" target in upstream.

# it build for smaller boards, but it won't be enough for larger

zephyr: Enable fatfs. Enables the fatfs filesystem in the zephyr port. Example usage with an SD card on the mimxrt1050_evk board: import zephyr, os bdev = zephyr.DiskAccess('SDHC') os.VfsFat.mkfs(bdev) os.mount(bdev, '/sd') with open('/sd/hello.txt','w') as f: f.write('Hello world') print(open('/sd/hello.txt').read())

zephyr: Enable littlefs. Enables the littlefs (v1 and v2) filesystems in the zephyr port. Example usage with the internal flash on the reel_board or the rv32m1_vega_ri5cy board: import os from zephyr import FlashArea bdev = FlashArea(FlashArea.STORAGE, 4096) os.VfsLfs2.mkfs(bdev) os.mount(bdev, '/flash') with open('/flash/hello.txt','w') as f: f.write('Hello world') print(open('/flash/hello.txt').read()) Things get a little trickier with the frdm_k64f due to the micropython application spilling into the default flash storage partition defined for this board. The zephyr build system doesn't enforce the flash partitioning when mcuboot is not enabled (which it is not for micropython). For now we can demonstrate that the littlefs filesystem works on frdm_k64f by constructing the FlashArea block device on the mcuboot scratch partition instead of the storage partition. Do this by replacing the FlashArea.STORAGE constant above with the value 4.

modzsensor.c \
zephyr: Initial implementation of machine.Pin. The integration with Zephyr is fairly clean but as MicroPython Hardware API requires pin ID to be a single value, but Zephyr operates GPIO in terms of ports and pins, not just pins, a "hierarchical" ID is required, using tuple of (port, pin). Port is a string, effectively a device name of a GPIO port, per Zephyr conventions these are "GPIO_0", "GPIO_1", etc.; pin is integer number of pin with the port (supposed to be in range 0-31). Example of pin initialization: pin = Pin(("GPIO_1", 21), Pin.OUT) (an LED on FRDM-K64F's Port B, Pin 21). There is support for in/out pins and pull up/pull down but currently there is no interrupt support.

modmachine.c \
zephyr/i2c: Add support for hardware i2c. Adds support for hardware i2c to the zephyr port. Similar to other ports such as stm32 and nrf, we only implement the i2c protocol functions (readfrom and writeto) and defer memory operations (readfrom_mem, readfrom_mem_into, and writeto_mem) to the software i2c implementation. This may need to change in the future because zephyr is considering deprecating its i2c_transfer function in favor of i2c_write_read; in this case we would probably want to implement the memory operations directly using i2c_write_read. Tested with the accelerometer on frdm_k64f and bbc_microbit boards.

zephyr: Implement block device protocol via zephyr disk access api. Introduces a new zephyr.DiskAccess class that uses the zephyr disk access api to implement the uos.AbstractBlockDev protocol. This can be used with any type of zephyr disk access driver, which currently includes SDHC, RAM, and FLASH implementations. The SDHC driver is enabled on the mimxrt1050_evk board. Only the standard block device protocol (without the offset parameter) can be supported with the zephyr disk access api, therefore this class cannot be used with file systems like littlefs which require the extended interface. In the future it may be possible to implement the extended interface in a new class using the zephyr flash api.

zephyr: Make sure that generated prj.conf is updated only on content changes. This is a typical problem with make: we want to trigger rebuilds only if file actually changed, not if its timestamp changed. In this case, it's aggravated by the fact that prj.conf depends on the value of BOARD variable, so we need to do some tricks anyway. We still don't try to detect if just BOARD changed, just try to generate new prj.conf.tmp every time (quick), but do actual replacement of prj.conf only if its content changed.
