The nrf52840-mdk-usb-dongle and pca10050 comes with a pre-flashed bootloader (OpenBootloader). This commit updates the boards "mpconfigboard.mk" to use DFU as default flashing method and set the corresponding BOOTLOADER settings such that nrf52840_open_bootloader_1.2.x.ld linker script is used. The default DFU flashing method can be disabled by issuing "DFU=0" when invoking make. This will lead to "segger" being used as default flashing tool. When using "DFU=0", the linker scripts will not compensate for any MBR and Bootloader region being present, and might overwrite them if they were present. The commit also removes the custom linker script specific to nrf52840-mdk-usb-dongle as it now points to a generic. Updated nrf52840-mdk-usb-dongle's README.md to be more clear on how to deploy the built firmware. The port README.md has also been updated. In the list of target boards a new column has been added to indicate which bootloader is present on the target board. And for consistency, changed all examples in the README.md to use "deploy" instead of "flash".
Adding variables that can be set from other linker scripts:
- _bootloader_head_size:
Bootloader flash offset in front of the application.
- _bootloader_tail_size:
Bootloader offset from the tail of the flash.
In case the bootloader is located at the end.
- _bootloader_head_ram_size:
Bootloader RAM usage in front of the application.
Updated calculations of application flash and RAM.
Updating to Black v20.8b1 there are two changes that affect the code in this repository: - If there is a trailing comma in a list (eg [], () or function call) then that list is now written out with one line per element. So remove such trailing commas where the list should stay on one line. - Spaces at the start of """ doc strings are removed. Signed-off-by: Damien George <damien@micropython.org>
Resolves dependencies for MICROPY_PY_TIME_TICKS which requires to link against nrfx_rtc.c functions by setting MICROPY_PY_MACHINE_RTCOUNTER to 1.
Example make command: make BOARD=actinius_icarus
Tested with the Particle Debugger on a Xenon.
Commit 6cea369b89b2223cf07ff8768e50dc39bbb770fe updated the TinyUSB submodule to a version based on nrfx v2.0.0. This commit updates the nrf port to work with the latest TinyUSB and nrfx v2.0.0.
Now that error string compression is supported it's more important to have consistent error string formatting (eg all lowercase English words, consistent contractions). This commit cleans up some of the strings to make them more consistent.
