Not working with OpenOCD - libusb_bulk_write error: LIBUSB_ERROR_TIMEOUT

[jonas-s-s-s]

Tried compiling with pico-sdk 2.0.0 (latest) and pico-sdk 1.4.0 (2022), both result into the same problem.

The version of OpenOCD I'm using is https://review.openocd.org/c/openocd/+/7344
Tried https://github.com/phdussud/openocd as well. However there was no change, if anything it was worse than the one mentioned above.

lsusb output:

I'm debugging an Raspberry pi zero (BCM2835), the openocd conf files I've tried were:
rp-zero.cfg (https://git.nah.nz/pi-zero-jtag/) (https://yeah.nah.nz/embedded/pi-jtag-u-boot/)
raspberry.cfg (https://github.com/sysprogs/openocd/blob/master/tcl/target/raspberry.cfg)
/openocd/scripts/target/bcm2835.cfg (shipped with OpenOCD by default)

Tried setting the adapter speed / adapter_khz to various values, nothing seemed to change the outcome.

The typical output I'm getting is the following:

$ sudo openocd -f /usr/local/share/openocd/scripts/interface/dirtyjtag.cfg -f pi-zero.cfg

Segmentation fault

With rp-zero.cfg and raspberry.cfg it crashes with LIBUSB_ERROR_TIMEOUT immediately as soon as GDB connects. With /openocd/scripts/target/bcm2835.cfg I'm able to connect with GDB, but as soon as I try to execute mon load_image it once again ends up crashing with LIBUSB_ERROR_TIMEOUT.
