If you have an m5stack, here are instructions to compile micropython firmware that includes all of Trezor's crypto code available as Python objects:
Install these prerequisites: https://github.com/loboris/MicroPython_ESP32_psRAM_LoBo/wiki/build
Build the custom Micropython firmware that includes trezor-crypto bindings:
git clone git@github.com:justinmoon/MicroPython_ESP32_psRAM_LoBo.git
cd MicroPython_ESP32_psRAM_LoBo/MicroPython_BUILD/
./BUILD.sh -v
./BUILD.sh -v flash
In another window run
git clone git@github.com:justinmoon/buidl-wallet.git
python3 -m pip install rshell
make sync
make repl
ctrl-dwill restart the devicectrl-a-dwill exit the repl
Plug wires into the usb-to-uart:
- rx <-> 17
- tx <-> 16
- gnd <-> gnd
(note: rx & tx criss-cross)
On host machine run cli.py <port>
Sync make folder=serial sync
The m5stack should start printing first 256 bytes every second
- I had to toggle the .endswith condition on line 193ish of /home/justin/dev/buidl-wallet/venv/lib/python3.7/site-packages/rshell/pyboard.py
- I was getting b'raw REPL; CTRL-B to exit\r\n>' instead of b'raw REPL; CTRL-B to exit\r\n' (caret at end)
- Copy this code over: https://github.com/justinmoon/micropython/blob/hd/ports/unix/src/main.py

- just now unplugging and plugging back in solved it
- this issue is on github dhylands/rshell#68

Come to think of itt .... I'm not actually using a pyboard ... do they mean "micropython" when they say "pyboard" or is the wrong code being executed?
