I bougt a new ESP32 DevkitC V4 from mouser, and I'm unable to connect with openocd to it via J-TAG pin.

J-TAG wiring is OK, everything is the same as in tutorial.
https://docs.espressif.com/projects/esp ... un-openocd

OpenOCD says:
openocd -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp-wroom-32.cfg

Code: Select all

Error: no device found
Error: unable to open ftdi device with vid 0403, pid 6010, description '*', serial '*' at bus location '*'

I found somewhere that I should change those ID's to the one which is in device manager, afterwards connection still doesn't work.

Code: Select all

Error: unsupported FTDI chip type: 0x0100
Error: unable to open ftdi device with vid 10c4, pid ea60, description '*', serial '*' at bus location '*'

What I should do to made it work? Thanks!

What jtag adapter are you using? vid 10c4, pid ea60 is the cp2102 uart adapter, not a jtag adapter.

I'm using J-Link Edu mini.

You are passing the following argument to OpenOCD: -f interface/ftdi/esp32_devkitj_v1.cfg — it tells OpenOCD that the adapter is "esp32 devkit", while in fact it is jlink. There is a jlink.cfg file in OpenOCD, maybe you can try it.

That's helped thanks.

But now OpenOCD says: (with VisualGDB)

Any ideas? I already googled a lot but nothing worked. It's a DevKitC with J-Link EDU.
Wiring is based on this image, is this correct? https://1.bp.blogspot.com/-RL8tkZprmjc/ ... pinout.png
