Warn : Failed to open device: LIBUSB_ERROR_NOT_FOUND. Warn : Bypassing JTAG setup events due to errorsĪnd if I plug the USB cable into a different hole (as suggested by DavidPowell) I get this Warn : Failed to open device: LIBUSB_ERROR_NOT_SUPPORTED.Įrror: JTAG scan chain interrogation failed: all onesĮrror: Check JTAG interface, timings, target power, etc.Įrror: Trying to use configured scan chain anyway…Įrror: esp32.cpu0: IR capture error saw 0x1f not 0x01 I’m running out of ideas now! Would someone kindly toss me a line please? I think I have done the right thing with Zadiq, though the recipe is a bit ambiguous. I have also seen all of the error reports you obtained. Yourigh, (or anybody else who has demonstrably figured this out)ĭid you ever get a working recipe to debug the ESP32 Feather Huzzah with a SEGGER JLink? I have trodden in your footsteps including even removing the LED, and setting the adapter speed much lower. 'internalConsoleOptions': 'openOnSessionStart' 'toolchainBinDir': 'D:/Cadence/SPB_Data/.platformio/packages/toolchain-xtensa32/bin', 'executable': 'd:/PROJECTS/01_GIT_REPOS/FRA_Sensor_platform/3-FW_SW/1-FW_device/FRA_SP_ESP32/.pioenvs/featheresp32/firmware.elf', I have the latest PlatformIO on Visual Studio Code Home 2.0.2♼ore 3.6.7 Upload simple program to board (pin toogle) - successfully running.connected USB of the ESP32 feather board to PC.ESP32 Feather connected to Jlink by this table:ĮDIT: ESP32 EN connected to pin 3(nTRST) of J-link.latest SEGGER J-link software installed (V6.44h).

I was trying many thing on different computer (including some of custom definitions of debug_tool) on different computer unsuccessfully.Ĭould you please help me to resolve this? I would love to give a unified debugger a chance (just bought a month plan). Unfortunately I did not find the fix for my issue. I am aware there have been posts on this topic and went through them.
