      @tudro Please make sure you have a wire connected between G23 and GND and reset the board before trying the erase. You should see a message "Waiting for download" on the serial terminal. Also make sure that all serial terminal programs & Pymakr plugins are disconnected when running esptool or the firmware update tool.

        building from fresh pulled git raises errors. There is a param that shall be specified?

        $ make BOARD=LOPY TARGET=boot
        Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.
        mkdir -p build/LOPY_868/release/bootloader/
        CC bootloader/bootloader.c
        xtensa-esp32-elf-gcc.exe: error: unrecognized command line option '-mfix-esp32-psram-cache-issue'
        make: *** [../py/mkrules.mk:47: build/LOPY_868/release/bootloader/bootloader.o] Error 1

          @colateral Please download the new xtensa compiler for your OS.

          The "esp32" port requires an xtensa gcc compiler, which can be downloaded from the Espressif website:

              @colateral Please use the following within msys2 to update the toolchain:

              # Automatically download precompiled toolchain, unpack at /opt/xtensa-esp32-elf/
              TOOLCHAIN_ZIP=xtensa-esp32-elf-win32-1.22.0-73-ge28a011-5.2.0.zip
              echo "Downloading precompiled toolchain ${TOOLCHAIN_ZIP}..."
              cd ~
              curl -LO --retry 10 http://dl.espressif.com/dl/${TOOLCHAIN_ZIP}
              cd /opt
              rm -rf /opt/xtensa-esp32-elf  # for upgrades
              unzip ~/${TOOLCHAIN_ZIP}
              rm ~/${TOOLCHAIN_ZIP}

                  @xykon Thanks. It was working. The mpy-cross was built and also the binary .. but there are issues on serial writing.
                  COM7 is ON and 'waiting for download'

                  but

                              $ make V=1 BOARD=LOPY LORA_BAND=USE_BAND_868 flash ESPPORT=COM7

                  With pycom firmware update and updater.py (changed according with Daniel above guidelines) ... it is working.

                    @xykon Thank you for the quick answer and sorry for the late reply (2 small kids :) ). You were right, i didn't have G23 and GND connected. I was able to reset the flash and make the lopy work again. Thank you very much

                      @colateral This seems to be due to a new tool we added that puts the ESP32 into firmware update mode if a Pytrack or Pysense is being used. It seems this tool doesn't work on Windows...

                      Please edit application.mk in the esp32 directory, search for flash: and comment the 4 lines as shown below:

                      flash: $(APP_BIN) $(BOOT_BIN)
                      #       $(ECHO) "Entering flash mode"
                      #       $(Q) $(ENTER_FLASHING_MODE)
                              $(ECHO) "Flashing project"
                              $(Q) $(ESPTOOLPY_WRITE_FLASH) $(ESPTOOL_ALL_FLASH_ARGS)
                      #       $(ECHO) "Exiting flash mode"
                      #       $(Q) $(EXIT_FLASHING_MODE)
                      

                      This will prevent the tool from running until we can fix it.

                        @daniel I have a serious problem with the new release. Setup:
                        Plain vanilla pycom image on a LoPy, flash was erased. I have a little script that connects as a STA:

                        import network
                        import time
                        from uos import uname
                        # setup as a station
                        wlan = network.WLAN(mode=network.WLAN.STA)
                        wlan.connect(ssid="my_ap", auth=(network.WLAN.WPA2, "my_passwd"))
                        for _ in range (200):
                            if wlan.isconnected():
                                wlan.ifconfig(config=("10.0.0.141", "255.255.255.0", "10.0.0.240",  "10.0.0.240"))
                                print(wlan.ifconfig())
                                break
                            else:
                                time.sleep_ms(50)
                        else:
                            print("Could not connect")
                        

                        and add the line
                        import connect
                        to main.py. If I boot, then it may connect, after a few reboots, it somehow locks, in that it does not connect to the AP any more. In that state, if I press Ctrl-D a few times, if get a core dump & Reset. The core dump starts with:

                        PYB: soft reboot
                        Guru Meditation Error of type LoadProhibited occurred on core  0. Exception was unhandled.

                        and finally and in a cold boot. Once in this state, the only way to recover and get WiFi again is erase flash and reload the firmware.

                            @xykon I tried already a few variants:
                            a) Pycom image or homebrew image: not difference
                            b) starting from main.py or manually: no difference
                            c) starting from the file system or as frozen bytecode: no change
                            d) with or without manual ip setting: makes a difference

                            If with manual IP setting I add a delay of 2 seconds between the isconnected state and IP setting, it is more stable. So it could be something related to the state machine if the WiFi stack.

                            But I had that manual IP setting before with all versions including 1.10.0b1 w/o problems.

                                  @xykon Thank you. Done. I did also 'make BOARD=LOPY clean' then make BOARD=LOPY TARGET=boot
                                  make BOARD=LOPY LORA_BAND=USE_BAND_868 TARGET=app

                                  and I have same result on flashing.

                                              $ make BOARD=LOPY LORA_BAND=USE_BAND_868  ESPPORT=COM7 flash

                                    @xykon I commented this in application.mk

                                    #PIC_TOOL = $(PYTHON) tools/pypic.py --port $(ESPPORT)
                                    #ENTER_FLASHING_MODE = $(PIC_TOOL) --enter
                                    #EXIT_FLASHING_MODE = $(PIC_TOOL) --exit
                                    

                                    and flashing was working.

                                    I don't know if everything goes fine with those lines commented. Seems that those lines are targeting flashing a pic microcontroller ... do we have this kind of microcontroller on our LopY and L01?

                                      Hello, with this firmware i'm having a problem with the deepsleep lib:
                                      Traceback (most recent call last):
                                      File "/flash/lib/deepsleep.py", line 151, in get_wake_status
                                      File "/flash/lib/deepsleep.py", line 79, in peek
                                      IndexError: bytes index out of range

                                      I downgraded the firmware to 1.9.2.b2 and the deepsleep started working fine again, so i assume it's something with the new firmware. Anybody had this problem?

                                      Thank you

                                        @emmanuel-goudot I had the same problem. After I upgraded xtensa tool to last version everything is working. You need to download and replace xtensa folder with the new software. Be sure the software that you install is inline with your OS: linux / windows and 32/64bit

                                          @colateral The pypic.py tool puts the esp32 into firmware update mode when using a Pytrack or Pysense which is controlled by a PIC microcontroller. This way you no longer need a jumper wire to do firmware upgrades.

                                            @xykon Thanks. We are using LoPy with pycom shield. We have also our own board based on L01. Both cases raise errors on that pypic serial connection . Can you enhance application.mk by adding some conditions in case that the pic is not present.?
