I`m trying to launch debug session in Eclipse with OpenOCD. Error log is the next:

Any ideas?

Error: JTAG scan chain interrogation failed: all ones

This usually indicates a connection problem between the jtag-interface and the ESP32. It can also occur if you reconfigure the GPIOs used for JTAG for something else in your program.

The problem was in .cfg file for OpenOCD module. I`ve added next lines:

Code: Select all

ftdi_layout_init 0x0008 0x000b
reset_config none

And all works now)
