The underlying issue seems to be reported much earlier. Under: "Launching OpenOCD" there is "Error: libusb_open() failed with LIBUSB_ERROR_NOT_SUPPORTED". This indicates some problem with USB driver. Since you are using Windows, I would redo all the steps under http://esp-idf.readthedocs.io/en/lates...

Yeah, well.. I can't base my design on the Wroover kits, can I? And I need to be able to debug on the final version of my H/W. ESP-WROVER-KIT has JTAG header exposed, so it can be connected the the final version of H/W Regarding separate adapters: * Olimex ARM-USB-OCD-H, works with "adapter_khz" at...

Have you tried setting 'RTC_CNTL_DG_PAD_FORCE_HOLD' bit in register 'RTC_CNTL_DIG_ISO_REG' to force holding of digital pads?

Hi @loboris,

Thank you for this great component and comprehensive demo.
As usual with your applications I got it up and running in no time.
This should be a great solution for battery powered projects.

I think the most comprehensive summary of places were to buy ESP32 modules is http://esp32.net/#Purchasing

Love this site for wealth of other well organized ESP32 information

This particular example is rather to demonstrate how to trigger interrupts depending on signal change on an input. But it also contains a "simple" check for GPIO level in line: https://github.com/espressif/esp-idf/blob/v2.0-rc2/examples/peripherals/gpio/main/gpio_test.c#L55 The actual check is done ...

It works now, thank you!! It did require connection of VCC to the JTAG for successful connection, and then ready to go! Thank you for update :D I see elsewhere on internet that people connect VCC as well for Segger J-link. This is not needed for Olimex ARM-USB-OCD-H. Both ESP32 DevKitC and ARM-USB-...

I'm using a ESP-WROOM-32. Does the change above mean that I should make any changes to my board... Yes, this change is recommended for ESP-WROOM-32 as well The guidelines says that this change is regarding pin 9, but this is not the same as pin 9 on the ESP-WROOM-32, right? Right, the RC circuit sh...

Flashing over JTAG is now implemented in official openocd-esp32 distribution - https://github.com/espressif/openocd-es ... 878cfa5dfe
