Error running openocd-dirtyjtag: syncbb_scan: Assertion `read == 32' failed.

I am using Raspberry Pi Pico W with openocd-dirtyjtag and trying to flash/debug NXP LPC1837. Got the following error when I try to start openocd. Please help me in resolving it.

I am getting this error too trying to use openocd-dirtyjtag with phdussud/pico-dirtyJtag on a Pico debugging an RPi4B.

Does anyone have any ideas what the problem might be?

I have the same issue. I'm using Raspberry Pico and trying to debug STM32F103C8
