Segger J-Link with openocd (XMC Link) fails during connection

[iosixllc]

I'm using ESP32-D2WD on a custom board and have disabled the SPI code/GPIO setup/etc on the JTAG pins (GPIOs 12-15). After switching XMC Link to libusb driver, I am able to get this far from msys2 console:

I'm using the latest firmware. I also tried with VisualGDB, which is supposed to work, and it has the same issue. Am I missing something? Thanks.

Having same problem. Any ideas/help from Espressif?

What's your hardware setup?
