Hi there,
will the MicroPython firmware build with the latest Espressif-SDK?
Is the ESP-BrakTooth fix included in the latest MicroPython release?
In the recommendations on readme.md i couldnt found some informations about the esp-idf patchlevel.
On page 4 the security advisory . lists the patched releases of esp-idf
are these patches are compatible with micropython and will be used for the latest downloads?

Re: BrakTooth
MicroPython is Opensource,you can try it on your own system
- First download and install ESP-IDF (in this example I used 4.2,with commit id 3212d62b2bf)
Code: Select all
WORKDIR="$HOME/workspace/micropython" mkdir -p $WORKDIR ## ESP-IDF clone # Clone ESP-IDF from github git clone -b v4.2 --recursive https://github.com/espressif/esp-idf.git cd $WORKDIR/esp-idf # checkout your desired patch git checkout 3212d62b2bf5bbfb7d399762770e872478c7ecdd git submodule update --init --recursive # Install ESP-IDF ./install.sh . ./export.sh
- Of course you also need the MicroPython sources:
Code: Select all
## MicroPython # Clone MicroPython from github cd $WORKDIR git clone https://github.com/micropython/micropython.git # build mpy-cross cd $WORKDIR/micropython/mpy-cross make -j4
- Now you can build your firmware and test it
Then connect to your ESP32 and reboot it.
Code: Select all
# first we need to set some environment variables WORKDIR="$HOME/workspace/micropython" export PATH="$WORKDIR/esp-idf/xtensa-esp32-elf/bin:$PATH" export IDF_PATH="$WORKDIR/esp-idf" cd $IDF_PATH source export.sh #optional customize BOARD-Variable to your hardware #export BOARD=GENERIC_SPIRAM ## Build Firmware #make clean cd $WORKDIR/micropython/ports/esp32 make submodules make -j4 # make deploy esptool.py -p /dev/ttyUSB0 -b 460800 write_flash -z 0x1000 build-GENERIC/firmware.bin
You should see today's builddateCode: Select all
screen /dev/ttyUSB0 # exit with [ctrl]+[a], [shift]+[k], [y] >>> import machine >>> machine.reset()
It looks like my example above worked with the breaktooth-commit.are these patches are compatible with micropython
But I have no idea how to see which ESP-IDF is being used for a specific MicroPython build.Is the ESP-BrakTooth fix included in the latest MicroPython release?
