HARDWARE: ESP32 240MHz, 320KB RAM, 4MB FlashĭEBUG: Current (esp-prog) External (esp-prog, iot-bus-jtag, jlink, minimodule, olimex-arm-usb-ocd, olimex-arm-usb-ocd-h, olimex-arm-usb-tiny-h, olimex-jtag-tiny, tumpa) Yep! I tried… > Executing task in folder 201205-104709-esp32dev: pio run -target upload Espressif ESP32 Dev Module Now of course since I’m on Windows I don’t have libusb so that part fails, but the tool also states it only works for Linux. While either adapting the esptool_ftdi_path value or commenting it out and uncommenting the line above.įor me, this leads to a successfull wrap (look at invocation in Verbose Upload) # exchange uploader fot esptool-ftdi.py and move esptool.py and old arguments as new args. # the new tool just takes as argument the complete invocation line of the old tool. # if this tool in your global PATH if not, use direct path variable belowĮsptool_ftdi_path = "C:/Users/Max/Downloads/esptool-ftdi-master/esptool-ftdi.py" "Installing esptool_ftdi's Python dependencies", # in PlatformIO's isolated python environment
FTDI FT230X PDF INSTALL
# check if we need to install pip modules (pyusb) Make the original esptool command a parameter of esptool-ftdi.pyĪnd then in the project’s root folder (same level as platformio.ini), add the wrap_esptool_ftdi.py file Import("env") In ~/.arduino15/packages/esp32/hardware/esp32/1.0.4/platform.txt (last but 1 line) I was hoping for a quick 'n dirty way to do this:
The learning delta is too big to warrant switching. If the above is correct, my familiarity (48hrs) with Platfomio is insufficient to make any further progress on this problem. The route I should follow is to use the advice in the documentation? The extent of which is between the headings Custom Upload Tool and CustomOCDTool?.
FTDI FT230X PDF CODE
This is a snippet from the source code to highlight that Platformio is different to the Arduino environment and NOT intended for me to modify my copy in some way?
If there is an easier route to program ESP32 custom board without physical access to the typical PROG & RESET buttons, I’d love to hear about it.Ĭan I confirm the advice you have kindly offered?
FTDI FT230X PDF SERIAL
This wrapper replaces all of the internal esptool.py serial routines with direct calls into libftdi1 and libusb-1.0 to dynamically switch between normal and bitbang modes as needed to make the typical reset-into-bootloader sequence work. On FTDI chips, CTS can be reconfigured as an output by entering bitbang mode. It only works with FTDI-based USB to serial adapters. This esptool.py wrapper lets you use RTS/CTS for ESP8266/ESP32 chip resets instead of the usual RTS/DTR. I quote directly from Jim Paris’s github: I think the critical word here is “WORK”? Yes, esptool will talk to a FT23x chips but esptool will not correctly control the reset/upload ( EN/IO0) sequence. But I don’t get why that script is needed? Doesn’t the esptool.py already work with all general USB-UART adapters? If there’s something to fix, why not fix it in the main esptool.py repo?
