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. 2019-12-20 05:31:50 +08:00			`# Required for zephyr.DiskAccess block devices`

zephyr: Enable usb mass storage class on mimxrt1050_evk. Enables the zephyr usb device stack and mass storage class on the mimxrt1050_evk board. The mass storage class is backed by the sdhc disk access driver, so it's now possible to browse and modify the contents of the SD card from a USB host (your PC). This is in preparation to support writing a main.py script to the SD card, and then executing it after the next reset. 2019-10-16 09:00:09 +08:00
