Notes on the Inkplate_ boards.
.. _Inkplate: https://soldered.com/collections/inkplate-e-paper-displays/
MicroPython
===========
Micropython for all of the Inkplate boards can be downloaded by cloning
the repository::
$ git clone https://github.com/SolderedElectronics/Inkplate-micropython.git
$ cd Inkplate-micropython
then the firmware can be flashed directly with esptool::
$ esptool --port /dev/ttyUSB0 erase_flash
$ esptool --port /dev/ttyUSB0 --chip esp32 --baud 115200 write_flash \
--flash_mode keep --flash_size keep --erase-all 0x1000 \
Inkplate-firmware.bin
under Debian, you may need to use ``--no-stub``, because of `#1043168`_::
$ esptool --port /dev/ttyUSB0 --chip esp32 --baud 115200 --no-stub \
write_flash --flash_mode keep --flash_size keep 0x1000 \
Inkplate-firmware.bin
.. _`#1043168`: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1043168
Then the libraries can be copied to the board from the local copy::
$ mpremote fs mkdir lib
$ mpremote fs cp <board>/package.json :lib/
$ mpremote fs cp <board>/<board>/*.py :lib/
$ mpremote fs cp Dependencies/*.py :lib/
e-radionica / crowdfunding models
---------------------------------
The old inkplate6 models from e-radionica / the crowdfunding are `not
supported yet by the current version of the Inkplate module
<https://github.com/SolderedElectronics/Inkplate-micropython/issues/47>`_,
but they can run the old version in the ``legacy`` branch::
$ esptool --port /dev/ttyUSB0 erase_flash
$ esptool --port /dev/ttyUSB0 --chip esp32 --baud 115200 write_flash \
--flash_mode keep --flash_size keep --erase-all 0x1000 \
esp32spiram-20220117-v1.18.bin
$ mpremote fs mkdir lib
$ mpremote fs cp mcp23017.py inkplate6.py image.py shapes.py gfx.py gfx_standard_font_01.py soldered_logo.py :lib/
Recovering from corrupted storage
---------------------------------
Because of `#1043168`_, at the moment Debian is missing the
(json-encoded binary) file
``/usr/lib/python3/dist-packages/esptool/targets/stub_flasher/stub_flasher_32.json``:
the option ``--no-stub`` may be used to perform *most* operations
(possibly at a slower speed), but ``erase-flash`` is not among the
supported ones.
In that case you may need to clone the upstream repository::
$ git clone https://github.com/espressif/esptool.git
and copy or link the correct file in the esptool package files::
# cd /usr/lib/python3/dist-packages/esptool/targets/stub_flasher
# ln -s /<path/to/repo>/esptool/esptool/targets/stub_flasher/1/esp32.json stub_flasher_32.json
and then regular commands, including ``erase_flash`` can be run.
